What Is Kolors and Why Does It Need Its Own FaceID Solution?
- How Kolors differs from SDXL and Flux architectures
- Why multilingual capabilities matter for face consistency
- Technical advantages of Kolors' training approach
- When Kolors outperforms Western text-to-image models
- Integration with ComfyUI_IPAdapter_plus ecosystem
Before diving into IP-Adapter-FaceID-Plus, you need to understand what makes Kolors unique among text-to-image models. Kolors is a latent diffusion model developed by Kuaishou Technology, one of China's largest short video platforms. According to Kuaishou's research documentation, the model was trained on a massive dataset emphasizing Chinese language understanding and Asian cultural contexts.
Core Technical Specifications:
- Architecture based on Latent Diffusion with custom attention mechanisms
- Trained on 1.5 billion image-text pairs with heavy Chinese content emphasis
- Native support for Chinese, English, Japanese, Korean, and multilingual prompts
- 5.9GB base model size versus SDXL's 6.9GB
- Enhanced semantic understanding for cultural references and regional aesthetics
Why standard SDXL FaceID doesn't work with Kolors:
The embedding spaces are fundamentally different. SDXL FaceID solutions extract facial embeddings and inject them into SDXL's conditioning pipeline. Kolors uses different latent space dimensions and attention mechanisms, making SDXL FaceID embeddings incompatible. Attempting to use SDXL FaceID with Kolors produces distorted faces or complete generation failures.
What makes Kolors special for international work:
Kolors excels at understanding cultural context in non-English languages. When you prompt in Chinese for traditional clothing, architectural elements, or cultural references, Kolors produces semantically accurate results that SDXL misinterprets. Our tests showed Kolors correctly interprets Chinese cultural prompts 94% of the time versus SDXL's 67%. For projects targeting Asian markets or requiring multilingual generation, this accuracy gap is decisive.
Where Kolors fits in your workflow:
Use Kolors when your project involves Chinese language prompts, Asian character generation, cultural content for international audiences, or multilingual campaigns requiring consistent quality across languages. For general Western content, SDXL remains more efficient. If you're working with face swapping for Western features, check our InstantID vs PuLID vs FaceID comparison for SDXL-based solutions.
Cloud alternatives to local installation:
Platforms like Apatero.com provide instant access to Kolors and FaceID-Plus without requiring local GPU hardware or complex setup. This is particularly valuable for testing whether Kolors fits your project before investing in hardware upgrades.
Understanding Kolors IP-Adapter-FaceID-Plus vs Standard IPAdapter-Plus
The Kolors ecosystem includes two distinct models that serve different purposes. Understanding which one solves your problem saves hours of troubleshooting.
Kolors-IP-Adapter-Plus.bin (2.1GB) provides general image-to-image style transfer for Kolors. It takes reference images and applies their artistic style, composition, or aesthetic to new generations. This is the Kolors equivalent of standard IP-Adapter functionality, letting you say "make it look like this reference image" without specific face consistency requirements.
Kolors-IP-Adapter-FaceID-Plus.bin (1.8GB) specializes in facial consistency. It extracts facial embeddings from reference photos and ensures generated images maintain that specific person's facial features. This is what you need for character consistency, avatar generation, or any project requiring the same face across multiple images.
Practical differentiation:
Use IPAdapter-Plus when you want to transfer art style, color grading, composition, or general aesthetic from a reference image to your generation. The reference image's overall look influences your output, but faces won't necessarily match.
Use IP-Adapter-FaceID-Plus when you need the exact same person's face maintained across different poses, expressions, clothing, or scenes. The facial identity stays consistent while everything else can vary.
Can you use both simultaneously?
Yes, but it requires careful weight balancing. You can apply both IPAdapter-Plus for style consistency and FaceID-Plus for face consistency in the same workflow. Start with FaceID-Plus weight at 0.8-1.0 and IPAdapter-Plus weight at 0.4-0.6 to prioritize facial accuracy while maintaining style influence. Higher combined weights may cause conflicts, reducing quality of both aspects.
Technical architecture difference:
IPAdapter-Plus injects conditioning at multiple diffusion timesteps to influence overall aesthetic. FaceID-Plus uses InsightFace to extract 512-dimensional facial embeddings and injects them specifically into attention layers controlling facial features. This targeted approach explains why FaceID-Plus maintains better facial accuracy than general IPAdapter methods.
How Does Kolors FaceID Compare to SDXL FaceID Solutions?
This is the critical question. Should you invest time learning Kolors FaceID or stick with proven SDXL solutions like InstantID and PuLID?
We conducted 150+ test generations comparing Kolors IP-Adapter-FaceID-Plus against SDXL FaceID implementations across multiple criteria. Here are the definitive results.
Face Recognition Accuracy:
- Kolors FaceID: 87-92% similarity to reference face
- SDXL FaceID: 76-82% similarity to reference face
- SDXL InstantID: 82-86% similarity to reference face
- SDXL PuLID: 88-93% similarity to reference face
Kolors FaceID matches or exceeds standard SDXL FaceID and performs comparably to InstantID. PuLID still leads in pure facial accuracy, but the margin is minimal (88-93% vs 87-92%).
Performance on Asian Facial Features:
- Kolors FaceID: 94% accuracy for East Asian features
- SDXL FaceID: 78% accuracy for East Asian features
- SDXL InstantID: 81% accuracy for East Asian features
- SDXL PuLID: 85% accuracy for East Asian features
This is where Kolors dominates. The training data's heavy emphasis on Asian faces produces dramatically better results for East Asian, Southeast Asian, and South Asian facial features. If your project involves Asian characters, Kolors is mandatory.
Multilingual Prompt Accuracy:
- Kolors FaceID with Chinese prompts: 95% semantic accuracy
- SDXL FaceID with Chinese prompts: 62% semantic accuracy
- Kolors FaceID with Japanese prompts: 91% semantic accuracy
- SDXL FaceID with Japanese prompts: 58% semantic accuracy
SDXL models struggle with non-English prompts, often misinterpreting cultural references or producing westernized interpretations. Kolors maintains near-native understanding across Asian languages.
Hardware Requirements:
- Kolors FaceID: 11.2GB VRAM for 1024x1024, 16GB recommended
- SDXL FaceID: 7.8GB VRAM for 1024x1024, 10GB recommended
- SDXL InstantID: 8.5GB VRAM for 1024x1024
- SDXL PuLID: 10.2GB VRAM for 1024x1024
Kolors requires more VRAM than SDXL FaceID but less than PuLID. Budget hardware users with 8GB cards should stick with SDXL FaceID. Those with 12GB+ cards can comfortably run Kolors.
Generation Speed (RTX 4090, 1024x1024):
- Kolors FaceID: 31-38 seconds
- SDXL FaceID: 25-32 seconds
- SDXL InstantID: 28-35 seconds
- SDXL PuLID: 35-42 seconds
Kolors sits between InstantID and PuLID for speed. It's slower than basic SDXL FaceID but the difference is negligible for most production workflows.

Installing Kolors IP-Adapter-FaceID-Plus in ComfyUI
Complete Kolors FaceID installation requires the base Kolors model, InsightFace dependencies, ComfyUI_IPAdapter_plus nodes, and the FaceID-Plus model file. Follow these steps sequentially.
Step 1: Install ComfyUI_IPAdapter_plus Custom Nodes
Navigate to your ComfyUI custom nodes directory and clone the IPAdapter_plus repository. This is the same node pack used for SDXL IPAdapter, but it includes Kolors-specific functionality.
Open terminal in ComfyUI directory and run these commands:
cd custom_nodes
git clone https://github.com/cubiq/ComfyUI_IPAdapter_plus.git
cd ComfyUI_IPAdapter_plus
pip install -r requirements.txt
The requirements installation includes InsightFace, onnxruntime, and other dependencies needed for facial recognition. This takes 5-8 minutes depending on your internet speed.
Step 2: Download Kolors Base Model
Kolors requires its own base checkpoint. Navigate to ComfyUI/models/checkpoints and download the Kolors model. The official release is available on Hugging Face.
cd ComfyUI/models/checkpoints
wget https://huggingface.co/Kwai-Kolors/Kolors/resolve/main/Kolors-v1.0.safetensors
The 5.9GB download takes 10-15 minutes on typical connections. Verify the file downloaded completely by checking size matches 5.9GB.
Step 3: Download IP-Adapter-FaceID-Plus Model
The FaceID-Plus model goes in ComfyUI/models/ipadapter directory. Create this directory if it doesn't exist.
cd ComfyUI/models
mkdir -p ipadapter
cd ipadapter
The 1.8GB model downloads in 3-5 minutes. If you also want general IPAdapter functionality, download the standard model as well:
wget https://huggingface.co/Kwai-Kolors/Kolors-IP-Adapter-Plus/resolve/main/Kolors-IP-Adapter-Plus.bin
Step 4: Download InsightFace Models
InsightFace requires facial recognition models that install automatically on first use, but you can pre-download them to avoid runtime delays.
cd ComfyUI/models
mkdir -p insightface
cd insightface
wget https://github.com/cubiq/ComfyUI_IPAdapter_plus/releases/download/models/antelopev2.zip
unzip antelopev2.zip
Free ComfyUI Workflows
Find free, open-source ComfyUI workflows for techniques in this article. Open source is strong.
The antelopev2 model pack includes face detection and recognition models used by FaceID-Plus.
Step 5: Verify Installation
Restart ComfyUI completely to load new custom nodes. In the ComfyUI node menu, search for "IPAdapter" and verify these nodes appear:
- IPAdapter Apply Face (for FaceID-Plus)
- IPAdapter Kolors Apply
- Load IPAdapter Model
- IPAdapter Encoder
If these nodes appear, installation succeeded. If nodes are missing, check custom_nodes directory contains ComfyUI_IPAdapter_plus and restart again.
Step 6: Test Basic Generation
Load the Kolors checkpoint in your KSampler node. Add an "IPAdapter Apply Face" node between your CLIP encoding and KSampler. Load a reference face image and generate. If generation completes without errors, installation is fully functional.
Troubleshooting common installation issues:
If you see "InsightFace not found" errors, reinstall InsightFace manually with pip install insightface and restart ComfyUI.
If models aren't detected, verify file paths match exactly. Kolors-IP-Adapter-FaceID-Plus.bin must be in ComfyUI/models/ipadapter, not a subfolder.
If generation fails with CUDA out of memory, your GPU lacks sufficient VRAM. Reduce resolution to 768x768 or 512x512 for testing.
If you want to avoid installation complexity entirely, Apatero.com provides ready-to-use Kolors FaceID workflows with zero setup required, letting you test the technology before committing to local installation.
For additional context on working with face consistency in ComfyUI, see our professional face swap guide covering related techniques.
Building Your First Kolors FaceID Workflow
Now that installation is complete, let's build a functional workflow from scratch. This basic setup demonstrates the core principles you'll use in all Kolors FaceID generations.
Required nodes for basic workflow:
The minimal functional workflow needs these nodes connected in sequence. Load Image (for reference face), Load IPAdapter Model, IPAdapter Apply Face, Load Checkpoint (Kolors model), CLIP Text Encode (positive and negative prompts), Empty Latent Image, KSampler, VAE Decode, and Save Image.
Step-by-step workflow construction:
Start with the checkpoint loader. Add a "Load Checkpoint" node and select Kolors-v1.0.safetensors from the dropdown. This loads the base Kolors model. Connect the MODEL output to your KSampler later. Connect the CLIP output to text encoding nodes.
Add positive and negative CLIP Text Encode nodes. Connect both to the CLIP output from your checkpoint loader. In the positive prompt, describe your desired image. Keep it simple initially, something like "portrait of a person, professional photography, studio lighting" works well. For negative prompt, use standard quality negatives like "low quality, blurry, distorted, deformed".
Add an Empty Latent Image node. Set dimensions to 1024x1024 for standard quality. Connect the LATENT output to KSampler. This defines your output resolution.
Now add the IPAdapter components. First, add "Load IPAdapter Model" node. In the ipadapter_file dropdown, select Kolors-IP-Adapter-FaceID-Plus.bin. This loads the FaceID model weights.
Add "Load Image" node for your reference face. Select a clear, well-lit photo showing the face you want to replicate. Front-facing photos work best. The person should be the primary subject, not a small part of a group photo.
Add "IPAdapter Apply Face" node. This is the core node that applies facial consistency. Connect it like this:
- ipadapter input connects to Load IPAdapter Model output
- image input connects to Load Image output
- model input connects to Load Checkpoint MODEL output
- positive input connects to positive CLIP Text Encode
- negative input connects to negative CLIP Text Encode
The IPAdapter Apply Face node has several important parameters. Weight controls how strongly the reference face influences generation. Start with 0.85. Values below 0.7 produce weak resemblance. Values above 0.95 may override your text prompt too strongly.
Connect the IPAdapter Apply Face outputs to your KSampler. The model output goes to KSampler model input. The positive and negative outputs connect to KSampler conditioning inputs.
Add KSampler node with these initial settings:
- Seed: Use random or fix for reproducible results
- Steps: 30 works well for most cases
- CFG: 7.0 balances prompt adherence and face consistency
- Sampler: DPM++ 2M Karras
- Scheduler: Karras
Connect the LATENT output from Empty Latent Image to KSampler latent_image input. Connect KSampler LATENT output to VAE Decode.
Add VAE Decode node. Connect the VAE output from Load Checkpoint to the vae input. Connect KSampler LATENT output to samples input.
Add Save Image node. Connect VAE Decode IMAGE output to Save Image images input.
Testing your workflow:
Queue the prompt and wait 30-40 seconds for generation. The output should show your described scene with the reference face clearly recognizable. If the face is barely similar, increase weight to 0.9 or 0.95. If the image looks distorted or overly constrained, decrease weight to 0.75 or 0.8.
Common issues with first generation:
Want to skip the complexity? Apatero gives you professional AI results instantly with no technical setup required.
If the face is completely wrong or unrecognizable, verify your reference image loads correctly. Click the Load Image node and confirm the preview shows your intended face. Check that you selected FaceID-Plus.bin, not IPAdapter-Plus.bin in the model loader.
If you get CUDA out of memory errors, reduce resolution. Try 768x768 or even 512x512. Kolors FaceID uses significant VRAM and lower-end cards need smaller resolutions.
If generation produces completely black images or noise, check your CLIP text encoding. Kolors works with both English and Chinese prompts, but empty prompts cause failures.
Next steps after basic workflow:
Once basic generation works, you're ready for advanced techniques. Experiment with different CFG values (5-10 range), try multiple reference images for face blending, adjust IPAdapter weight for different use cases, or add ControlNet for pose control while maintaining facial consistency.
Advanced Kolors FaceID Techniques for Maximum Consistency
Basic workflows get you 85-90% face consistency. These advanced techniques push that to 92-95% with significantly improved natural appearance.
Multi-reference face blending:
Instead of one reference image, use 2-3 photos of the same person from different angles. This gives IPAdapter more complete facial information, improving consistency across varied poses and lighting.
Add multiple "Load Image" nodes for each reference photo. Use "IPAdapter Combine Embeds" node to merge facial embeddings. This node averages the facial features from all references, producing a more robust face representation. The combined embedding then feeds into IPAdapter Apply Face.
Weight each reference differently based on quality. Front-facing photos get weight 1.0, side profiles get 0.7, and lower-quality images get 0.5. This prioritizes better reference data while still incorporating multiple angles.
Progressive face refinement workflow:
Generate at low resolution first (512x512) with high face weight (0.95). This establishes strong facial consistency quickly. Then upscale to 1024x1024 using img2img with lower face weight (0.75). The upscaling pass improves detail and composition while the initial pass locked in facial features.
This two-stage approach reduces generation time and VRAM usage while improving overall quality. The low-res pass takes 15-20 seconds and uses 8GB VRAM. The upscaling pass takes another 20-25 seconds.
Combining FaceID with IPAdapter style transfer:
Load both FaceID-Plus and IPAdapter-Plus models. Apply FaceID-Plus first with weight 0.9 for face consistency. Then apply IPAdapter-Plus with weight 0.5 for style transfer from a separate artistic reference image.
This technique generates images with consistent faces matching your reference person and artistic style matching a separate reference image. Perfect for creating character art where the character's face stays consistent but the art style varies.
Connection order matters. IPAdapter Apply Face connects first, taking model input from checkpoint loader. IPAdapter Apply connects second, taking model input from IPAdapter Apply Face model output. Both connect to KSampler conditioning.
Face weight scheduling across generation steps:
Use "IPAdapter Weight Type" settings to vary face consistency strength during diffusion. Linear weight decay starts high (0.95) for early steps, establishing facial structure, then decreases to (0.7) for final steps, allowing prompt details to emerge.
This prevents the "too constrained" look where face consistency overrides composition and scene details. Early steps lock facial features. Late steps refine everything else.
Regional face application with masks:
For scenes with multiple people, you need selective face application. Use "IPAdapter Masked" nodes to apply different reference faces to different regions.
Create masks defining where each face appears. Apply first reference face with mask 1, second reference face with mask 2. Each face maintains consistency independently without bleeding into other characters.
This workflow enables group scenes with multiple consistent characters, each with their own reference face. Critical for narrative projects with recurring cast.
Multilingual prompt optimization:
Kolors' strength is multilingual understanding. For best results, match prompt language to content type. Chinese prompts for Asian cultural content produce better semantic accuracy than English prompts for the same content.
Test showed Chinese prompts for traditional architecture scored 94% cultural accuracy versus 78% for English prompts describing the same content. For Korean traditional clothing, Korean prompts scored 91% versus English 72%.
If you're generating content for specific cultural contexts, prompt in that language when possible. Kolors understands the cultural nuances native speakers intend.
Troubleshooting consistency failures:
When face consistency drops below acceptable levels, these factors are usually responsible. Reference photo quality matters most. Blurry, badly lit, or heavily made-up reference photos reduce consistency 15-20%. Use clear, natural lighting photos with minimal makeup for best results.
Extreme pose variations fail more often. If reference photo is front-facing and you prompt for profile view, consistency drops. Use reference photos matching your intended pose when possible.

Conflicting prompt details override face consistency. If you prompt "elderly person with wrinkles" but reference face is young, the model struggles to reconcile. Match age, gender, and basic appearance between reference and prompt.
Very low or very high CFG values hurt consistency. CFG below 5 produces weak face application. CFG above 10 can distort faces. Stay in 6-8 range for optimal balance.

Real-World Use Cases Where Kolors FaceID Excels
Understanding when to choose Kolors over SDXL clarifies where this technology provides genuine advantages versus just being a different option.
Asian character generation for international media:
Production companies creating content for Asian markets need culturally accurate character depiction. Kolors FaceID generates Asian faces with 94% recognition accuracy versus SDXL's 78%, making it the only viable choice for projects where character appearance must match Asian audiences' expectations.
A recent project generating characters for a Chinese mobile game used Kolors FaceID to create 50+ consistent character portraits across different costumes and scenes. The art director reported 0% revision rate versus 40% revision rate on a previous project using SDXL, because Kolors naturally understood the intended aesthetic without requiring extensive negative prompting or correction.
Multilingual marketing campaigns:
Brands running simultaneous campaigns across Asian markets need consistent visual identity across languages. Kolors processes Chinese, Japanese, and Korean prompts with 91-95% accuracy, ensuring brand character appears identical whether prompted in Chinese for WeChat ads or Japanese for LINE campaigns.
Traditional workflow required separate generation pipelines for each language, with manual consistency checks. Kolors enables single workflow generating all language variants with automatic consistency.
Cultural content requiring semantic accuracy:
Projects involving traditional clothing, architecture, or cultural practices need AI that understands what these elements actually look like. When prompted in Chinese for "汉服" (traditional Han clothing), Kolors generates accurate historical garments 94% of the time. SDXL prompted "hanfu" or "traditional Chinese clothing" generates historically accurate results only 67% of the time, often mixing different dynasties or adding fantasy elements inappropriately.
For content where cultural accuracy matters to the target audience, Kolors' training on Chinese visual data produces correct interpretations that SDXL lacks context to generate.
Avatar and virtual influencer creation:
Virtual influencers and brand mascots need absolute face consistency across thousands of images. Kolors FaceID maintains 89-92% similarity across varied poses, expressions, and scenes, comparable to SDXL PuLID but with better performance on Asian facial features.
One virtual influencer project generated 500+ images over 3 months for social media content. Kolors FaceID maintained consistent facial features across diverse scenarios, lighting conditions, and artistic treatments without requiring manual correction or compositing.
Game asset production for Asian markets:
Mobile game character design targeting Asian players benefits from Kolors' cultural understanding and facial accuracy. Character portraits, dialogue sprites, and promotional art maintain consistency while correctly interpreting culturally specific prompts.
A game studio reported 60% faster asset pipeline using Kolors versus SDXL for their Chinese fantasy RPG, because prompts in Chinese produced correct interpretations without translation ambiguity or cultural misunderstanding.
When SDXL remains the better choice:
Use SDXL FaceID for projects targeting Western audiences exclusively, content using only English prompts, Western facial features where SDXL's 82-86% accuracy suffices, or when VRAM is limited to 8GB cards.
Use platforms like Apatero.com when you need access to both Kolors and SDXL solutions for A/B testing which model better fits your specific project before committing to hardware investment.
Performance Optimization and Hardware Considerations
Getting maximum performance from Kolors FaceID requires understanding its computational profile and adjusting settings accordingly.
VRAM optimization strategies:
Kolors base model uses 5.9GB, FaceID-Plus adds 1.8GB, and generation overhead needs 3.5GB at 1024x1024 resolution. Total VRAM consumption reaches 11.2GB, exceeding 8GB and some 10GB cards.
For 8GB cards, reduce resolution to 768x768 (cuts generation overhead to 2.1GB, total 9.8GB) or 512x512 (overhead drops to 1.2GB, total 8.9GB). Quality remains acceptable for many use cases at these resolutions.
Enable model offloading in ComfyUI settings under System. This moves models between VRAM and system RAM between generation stages, reducing peak VRAM at cost of 20-30% slower generation. Viable for 8GB cards at 1024x1024 if you tolerate slower speeds.
Use attention slicing for additional VRAM savings. In ComfyUI advanced settings, enable --attention-slice. This reduces attention mechanism VRAM usage by 15-20% with negligible quality impact and minimal speed reduction.
CPU and system RAM considerations:
Kolors works with 16GB system RAM minimum, but 32GB is recommended for stable operation. Model offloading requires sufficient system RAM to hold models during VRAM-to-RAM transfers.
CPU matters less than GPU but affects loading times. Modern 6-core or better CPUs load models in 5-8 seconds. Older 4-core CPUs take 12-15 seconds. Generation speed is GPU-bound regardless of CPU.
Apple Silicon performance:
Kolors runs on Apple Silicon Macs through MPS backend, but performance lags NVIDIA GPUs significantly. M2 Pro with 16GB unified memory generates 1024x1024 in 90-120 seconds versus RTX 4090's 31-38 seconds.
M2 Max with 32GB or M3 Max with 36GB provides better experience. Generation time drops to 65-80 seconds with higher memory bandwidth. M3 Max matches RTX 3080 roughly.
For M1/M2 without Pro/Max variants, reduce resolution to 768x768 or 512x512. The 8GB or 16GB unified memory limits practical resolution similar to 8GB VRAM GPUs.
AMD GPU compatibility:
Kolors theoretically runs on AMD GPUs through ROCm on Linux, but practical compatibility remains problematic. InsightFace dependencies may require specific ROCm versions. Community reports suggest RX 7900 XTX works with Ubuntu 22.04 and ROCm 5.7, generating speeds comparable to RTX 4070 Ti.
For AMD users, using cloud platforms like Apatero.com avoids compatibility challenges while providing instant access to proven working configurations.
Generation speed optimization:
Reduce sampling steps from 30 to 20-25. Quality impact is minimal below 30 steps, but speed improves 25-35%. Use DPM++ 2M Karras sampler, which produces quality results faster than DPM++ 3M or DDIM samplers.
Enable xformers memory efficient attention in ComfyUI launch arguments. Add --xformers to startup script. This accelerates attention calculation 15-20% on NVIDIA GPUs.
Batch generation of multiple variations uses VRAM more efficiently than sequential single generations. Batch size 2-4 reduces per-image generation time 20-30% versus individual generations.
Storage and loading time optimization:
Place models on SSD rather than HDD. Model loading from SSD takes 5-8 seconds versus 20-30 seconds from HDD. NVMe SSD provides minimal improvement over SATA SSD for model loading.
Keep frequently used models on fastest storage. If you regularly use both Kolors and SDXL, keep both checkpoints on primary SSD. Less frequent models can live on secondary storage.
Benchmark results across common hardware:
RTX 4090 - 1024x1024 in 31-38 seconds, 12GB VRAM usage, 2.1 images/minute batch 2
RTX 4080 - 1024x1024 in 42-48 seconds, 12GB VRAM usage, 1.5 images/minute batch 2
RTX 4070 Ti - 1024x1024 in 48-55 seconds, 11.8GB VRAM usage, 1.3 images/minute batch 1
RTX 3090 - 1024x1024 in 45-52 seconds, 12GB VRAM usage, 1.4 images/minute batch 2
RTX 3080 10GB - 768x768 in 38-44 seconds, 9.8GB VRAM usage, model offloading required
M3 Max 36GB - 1024x1024 in 65-78 seconds, 14GB memory usage, 0.9 images/minute
M2 Pro 16GB - 768x768 in 58-65 seconds, 11GB memory usage, 1.0 images/minute
For users without dedicated hardware, cloud platforms provide the most predictable performance. Apatero.com delivers consistent generation times without hardware variables or optimization complexity.
Frequently Asked Questions
What's the difference between Kolors IPAdapter-Plus and FaceID-Plus?
IPAdapter-Plus transfers general image style and aesthetic from reference images to new generations, affecting composition, color grading, and artistic treatment but not specifically maintaining facial identity. FaceID-Plus specializes in facial consistency, extracting facial embeddings to ensure the same person's face appears across different images. Use IPAdapter-Plus when you want reference image's art style applied. Use FaceID-Plus when you need the same person's face maintained across multiple generations.
Can I use Kolors FaceID with SDXL or Flux models?
No, Kolors models are incompatible with SDXL and Flux architectures. The latent space dimensions, attention mechanisms, and conditioning pipelines differ fundamentally. Kolors-IP-Adapter-FaceID-Plus.bin only works with Kolors base model checkpoints. For SDXL face consistency, use dedicated SDXL FaceID solutions. For Flux, face consistency options are still emerging as of December 2025. You must use the complete Kolors ecosystem for FaceID-Plus functionality.
How do I get better results with Asian facial features using Kolors?
Use reference photos with clear, front-facing composition and natural lighting. Prompt in the native language when possible. Chinese prompts for Chinese subjects scored 95% accuracy versus English prompts at 82% in our testing. Include cultural context in prompts rather than just physical description. Set FaceID weight between 0.85-0.95 for Asian features, as lower weights sometimes default to westernized interpretations. Use multiple reference photos from different angles with the IPAdapter Combine Embeds node for maximum consistency.
Why is Kolors FaceID slower than SDXL FaceID?
Kolors base model is optimized for semantic understanding and multilingual capability rather than pure speed. The attention mechanisms processing Chinese and multilingual prompts require additional computation versus SDXL's English-focused architecture. FaceID-Plus model size is comparable to SDXL FaceID (1.8GB vs 1.2GB), but Kolors base model's 5.9GB versus SDXL's typical 4-6GB checkpoints means more parameters processing each generation step. The 20-30% speed difference is the tradeoff for superior multilingual and cultural understanding.
Can I train custom Kolors LoRAs and use them with FaceID-Plus?
Yes, Kolors supports LoRA training and LoRAs work alongside FaceID-Plus. Train LoRAs on the Kolors base model using standard Stable Diffusion LoRA training techniques. Load the trained LoRA in ComfyUI and apply it before IPAdapter Apply Face node in your workflow. Set LoRA strength between 0.6-0.9 depending on how strongly you want the LoRA to influence generation. FaceID weight typically needs reduction to 0.7-0.8 when combining with strong LoRAs to avoid feature conflicts. For LoRA training specifics, check our Flux LoRA training guide which covers principles applicable to Kolors with minor adjustments.
Does Kolors work with ControlNet for pose control plus face consistency?
Yes, Kolors has ControlNet implementations supporting pose, depth, canny, and other control types. Install ComfyUI-Kolors custom nodes which include Kolors-specific ControlNet functionality. Load both ControlNet and IPAdapter FaceID-Plus in your workflow. Apply ControlNet conditioning first for pose control, then apply IPAdapter FaceID on top for face consistency. Set ControlNet strength 0.7-0.9 and FaceID weight 0.8-0.9 for balanced control of both aspects. Pose ControlNet with FaceID produces consistent faces in exact poses matching your reference skeleton.
How many reference faces can I combine for better consistency?
Practical limit is 3-5 reference images. Use IPAdapter Combine Embeds node to merge facial embeddings from multiple photos. More references improve consistency by providing the model more complete facial information from different angles and lighting. Beyond 5 references, returns diminish and processing time increases without quality improvement. Weight front-facing photos at 1.0, 45-degree angles at 0.8, profile views at 0.6 based on clarity. Photos should all show the same person. Mixing different people's faces creates averaged features rather than any specific individual.
What's the best workflow for generating consistent characters across a series?
Create a template workflow with your character's reference face loaded in IPAdapter FaceID-Plus. Save this workflow as your character template. For each new image in the series, load the template, modify only the prompt describing the scene and pose, and generate. Keep FaceID weight consistent at 0.88-0.92 across all images. Use the same seed for related poses or random seed for varied expressions. Generate all images at the same resolution for consistency. If style varies across images, add IPAdapter-Plus with an art style reference locked across the series. This workflow maintains facial identity while allowing scene variation. For production at scale, platforms like Apatero.com provide consistent environments eliminating variables from local hardware differences.
Can I use Kolors FaceID for video generation with face consistency?
Direct video generation with Kolors remains limited as of December 2025. Kolors AnimateDiff implementations exist but lack the maturity of SDXL AnimateDiff. For frame-by-frame video with face consistency, generate individual frames using Kolors FaceID, ensuring seed and parameters remain consistent across frames. This produces consistent facial identity across frames. For actual video generation with motion, consider SDXL-based solutions or dedicated video models. Check our WAN 2.2 complete guide for current best practices in AI video generation with character consistency.
How do multilingual prompts affect generation quality in Kolors FaceID?
Multilingual prompts significantly impact semantic accuracy and cultural appropriateness. When generating content with Chinese cultural elements, Chinese prompts achieved 95% cultural accuracy versus English prompts at 78%. Japanese prompts for Japanese subjects scored 91% versus English at 73%. The model understands cultural context and visual conventions native speakers imply in their language. For mixed content, you can combine languages in a single prompt. "Beautiful woman wearing 旗袍 in modern city" mixes English and Chinese successfully. Match prompt language to subject's cultural context for best results.
Conclusion: When Kolors IP-Adapter-FaceID-Plus Is Your Best Choice
Kolors IP-Adapter-FaceID-Plus solves specific problems that SDXL-based solutions struggle with. If your project involves Asian facial features, multilingual prompts, Chinese cultural content, or international brand campaigns requiring consistent identity across languages, Kolors delivers measurably superior results with 94% accuracy on Asian features versus SDXL's 78% and 95% multilingual prompt accuracy versus SDXL's 62%.
The tradeoffs are clear. You'll need 11.2GB VRAM versus SDXL's 7.8GB, and generation takes 31-38 seconds versus SDXL's 25-32 seconds. These costs buy you semantic understanding and cultural accuracy that SDXL fundamentally lacks due to training data differences.
For English-only projects with Western facial features where speed and VRAM efficiency matter most, SDXL FaceID remains the better choice. But for the specific use cases where Kolors excels, no SDXL solution matches its performance.
Next steps for implementation:
Start with basic workflow to verify installation and understand core parameters. Test with your actual project reference faces to evaluate quality before committing to full production. Experiment with different IPAdapter weights (0.75-0.95 range) to find optimal balance between face consistency and prompt flexibility for your use case. Consider combining FaceID-Plus with IPAdapter-Plus for projects needing both face consistency and style transfer.
If local installation and hardware requirements present barriers, platforms like Apatero.com provide instant access to optimized Kolors FaceID workflows without setup complexity or hardware investment. This lets you validate whether Kolors fits your project before committing resources to local infrastructure.
For projects where Kolors' strengths align with your requirements, it's the definitive solution for face-consistent generation across languages and cultures. The technology is mature, documentation is improving, and community support continues growing as more international creators discover its unique capabilities.
