The Complete ComfyUI Low-VRAM Survival Guide - Run FLUX & Video Models on 4-8GB GPUs 2025
Master running FLUX, video models, and advanced workflows on 4-8GB GPUs using GGUF quantization, two-stage generation, and Ultimate SD Upscale techniques in ComfyUI.

You've got a budget GPU with 4-8GB of VRAM, and everyone's talking about FLUX models and AI video generation like they require a data center. The truth? You absolutely can run these advanced models on limited hardware - you just need to know the right techniques.
This isn't about compromising quality or settling for inferior results. With GGUF quantization, two-stage generation workflows, and smart optimization strategies, you'll generate stunning 1024px images on 4GB GPUs and custom character videos on 8GB cards.
The secret weapon is understanding how model quantization works and leveraging ComfyUI's flexible workflow system to work around VRAM limitations without sacrificing creative capability.
Understanding VRAM Limits - Why Most Guides Get It Wrong
Most ComfyUI tutorials assume you have 12GB+ of VRAM and tell budget GPU owners they're out of luck. That's fundamentally wrong and ignores the massive optimization potential available through modern quantization techniques.
The Real VRAM Requirements: Traditional model loading assumes fp16 precision and full model weights in VRAM. A FLUX Dev model at fp16 requires roughly 23GB just for the model weights, completely impossible on consumer hardware.
But models don't need to run at full precision to produce quality results. Quantization techniques reduce memory requirements by 50-80% with minimal quality impact.
What Actually Uses Your VRAM:
Component | Typical Usage | Optimization Potential |
---|---|---|
Model weights | 60-80% | Very high (quantization) |
Activation tensors | 10-20% | Medium (resolution control) |
Intermediate results | 5-10% | High (sequential processing) |
System overhead | 5-10% | Low (minimal impact) |
The GGUF Revolution: GGUF (GPT-Generated Unified Format) quantization allows models to run at dramatically reduced precision levels. A Q5 quantized model uses roughly 1/4 the memory of the fp16 version while maintaining 95%+ quality.
This technology transforms ComfyUI from a high-end GPU exclusive tool into something accessible on budget hardware.
Why Cloud Platforms Don't Tell You This: Services like Apatero.com provide instant access to enterprise GPUs, which is fantastic for professional work. But understanding low-VRAM optimization gives you creative freedom without ongoing cloud costs.
The choice between optimization and cloud access depends on your specific workflow needs and budget constraints. For beginners still learning ComfyUI basics, check out our ComfyUI basics guide and essential custom nodes guide to understand the workflow foundation. For cloud alternatives, see our Comfy Cloud launch article.
GGUF Quantization Explained - Your Low-VRAM Superpower
GGUF quantization is the single most important technique for running modern AI models on limited VRAM. Understanding how it works helps you choose the right quantization level for your hardware.
Quantization Levels Breakdown:
Quantization | VRAM Usage | Quality | Speed | Best For |
---|---|---|---|---|
Q2 | Minimal | 70% | Very fast | 4GB extreme cases |
Q3 | Very low | 80% | Fast | 4GB standard |
Q4 | Low | 90% | Moderate | 6GB optimal balance |
Q5 | Moderate | 95% | Normal | 8GB quality focus |
Q6 | High | 98% | Slower | 10GB+ minimal compromise |
Q8 | Very high | 99% | Slow | 12GB+ perfectionist |
How Quantization Works: Neural network weights are normally stored as 16-bit floating point numbers. Quantization converts these to lower precision representations like 4-bit or 5-bit integers, reducing memory requirements proportionally.
The model file size directly indicates VRAM requirements. A 3.1GB GGUF model needs roughly 3.1GB of VRAM for the weights, plus overhead for processing.
Quality vs VRAM Trade-offs: Lower quantization levels introduce subtle quality degradation. Q5 is generally considered the sweet spot - noticeable VRAM savings with minimal quality impact that most users can't detect in blind comparisons.
Q2 and Q3 models show visible quality reduction in fine details and text rendering, but remain perfectly usable for many creative applications.
Installing GGUF Support: You need the ComfyUI-GGUF custom node to use quantized models. Install it through ComfyUI Manager by searching for "GGUF" and clicking install. If you encounter installation issues, see our red box troubleshooting guide.
After installation, restart ComfyUI to load the new node types that support GGUF model loading.

For users who want to avoid model management complexity entirely, platforms like Apatero.com provide curated, optimized models without manual downloads or configuration.
The Ultimate Low-VRAM Workflow - 1024px on 4GB
This workflow technique generates high-resolution images on GPUs with only 4GB of VRAM by combining GGUF quantization with two-stage generation and Ultimate SD Upscale.
Workflow Architecture Overview: Stage 1 generates a 512x512 base image using a Q3 or Q5 GGUF model. Stage 2 upscales the result to 1024px or higher using Ultimate SD Upscale with tiled processing.
This approach keeps VRAM usage under 4GB while producing results comparable to native high-resolution generation on high-end hardware.
Stage 1 - Base Generation Setup:
Component | Configuration | Reason |
---|---|---|
Model | FLUX Dev Q3 GGUF | Minimal VRAM footprint |
Resolution | 512x512 | Low activation memory |
Steps | 20-25 | Balance speed/quality |
Sampler | Euler or DPM++ 2M | Efficiency |
Batch Size | 1 | Prevent VRAM overflow |
Node Setup for GGUF Loading: Replace the standard Load Checkpoint node with the GGUF Model Loader node. Point it to your downloaded GGUF model file location.
Connect the GGUF loader output to your KSampler exactly as you would a normal checkpoint loader - the node interfaces are compatible.
Stage 2 - Ultimate SD Upscale: Install the Ultimate SD Upscale extension through ComfyUI Manager if you don't have it. This extension provides tiled upscaling that processes images in small chunks, keeping VRAM usage constant regardless of output size.
Configure the upscaler with 512x512 tile size, 64px overlap for seamless blending, and your choice of upscale model - Ultrasharp or 4x_NMKD_Superscale work well.
Complete Workflow Structure:
- GGUF Model Loader (FLUX Dev Q3)
- CLIP Text Encode for positive prompt
- CLIP Text Encode for negative prompt
- Empty Latent Image (512x512)
- KSampler (20 steps, Euler, CFG 7)
- VAE Decode
- Ultimate SD Upscale (2x, 512 tiles, 64 overlap)
- Save Image
Expected Performance:
Hardware | Generation Time | Quality | Notes |
---|---|---|---|
4GB GPU | 2-4 minutes | Excellent | Q3 model recommended |
6GB GPU | 1.5-3 minutes | Excellent | Q4 or Q5 possible |
8GB GPU | 1-2 minutes | Exceptional | Q5 recommended |
Troubleshooting VRAM Overflows: If you still hit VRAM limits, reduce the base resolution to 448x448 or enable the --lowvram launch flag when starting ComfyUI. This forces sequential model component loading for maximum memory efficiency.
Close all other applications using GPU resources including browsers with hardware acceleration enabled.
Running FLUX Models on Budget Hardware
FLUX models represent the cutting edge of open-source image generation, but their size makes them challenging on limited VRAM. Here's how to run them effectively on 4-8GB GPUs.
FLUX Model Variants:
Model | Original Size | Q3 Size | Q5 Size | Quality | Best Use |
---|---|---|---|---|---|
FLUX Dev | 23GB | 5.8GB | 9.5GB | Highest | General purpose |
FLUX Schnell | 23GB | 5.8GB | 9.5GB | High speed | Iteration |
FLUX LoRA | +2GB | +0.5GB | +0.8GB | Variable | Style control |
Optimal Settings by VRAM Tier:
4GB Configuration: Use FLUX Dev Q2 or Q3 GGUF with 512x512 base resolution. Enable --lowvram flag and unload models when not in use. Generate single images sequentially. Upscale in a separate workflow step.
6GB Configuration: Use FLUX Dev Q3 or Q4 GGUF with 640x640 base resolution. Standard ComfyUI launch flags work. Can handle simple LoRAs with careful memory management. Two-stage upscaling still recommended for 1024px+.
8GB Configuration: Use FLUX Dev Q5 GGUF with 768x768 base resolution. Full LoRA support including multiple LoRAs. Can generate 1024px directly with careful workflow design. Two-stage approach still faster for >1024px.
FLUX-Specific Optimization Techniques: FLUX benefits particularly from the Euler sampler which requires fewer steps than DPM++ variants. Use 15-20 steps instead of 25-30 for equivalent quality.
The model's architecture allows aggressive CFG scale reduction - values of 3.5-5.0 produce excellent results compared to SD's typical 7-12 range.
LoRA Integration on Limited VRAM: LoRAs add VRAM overhead proportional to their size and complexity. Budget 500MB-1GB per LoRA on top of base model requirements.
Load LoRAs sequentially if using multiple - don't try to load all simultaneously on 6GB hardware. Apply one LoRA, generate, unload, apply the next.
Performance Comparison:
Setup | VRAM Used | Gen Time | Quality | Practical? |
---|---|---|---|---|
FLUX fp16 local | 23GB+ | N/A | - | Impossible on consumer GPUs |
FLUX Q2 4GB | 3.5GB | 180s | Good | Usable compromise |
FLUX Q5 8GB | 7.2GB | 90s | Excellent | Highly recommended |
Cloud (Apatero) | 0GB local | 10s | Perfect | Best for production |
For professional workflows requiring consistent FLUX generation at maximum quality, cloud platforms like Apatero.com eliminate VRAM management entirely while providing faster generation times.

Video Generation on 8GB - Wan2.2 with LoRA Support
AI video generation has traditionally required 16GB+ VRAM, but Wan2.2 GGUF models bring this capability to 8GB GPUs with full LoRA support for custom character videos. For a complete comparison of video models, see our video generation showdown.
Wan2.2 Video Model Overview: Wan2.2 (also called Wan2.1 in some sources) is Alibaba's open-source video generation model that produces smooth, high-quality video clips from text or image prompts.
The GGUF quantized versions make this previously inaccessible technology work on consumer hardware.
VRAM Requirements by Configuration:
Setup | VRAM Usage | Video Quality | Frame Rate | Duration |
---|---|---|---|---|
Wan2.2 Q2 | 4.5GB | Acceptable | 24fps | 2-3s |
Wan2.2 Q3 | 6.0GB | Good | 24fps | 3-4s |
Wan2.2 Q5 | 8.5GB | Excellent | 30fps | 4-5s |
With LoRA +1GB | Add 1GB | Variable | Same | Same |
Installing Wan2.2 for ComfyUI: Download the Wan2.2 GGUF model files from HuggingFace or CivitAI - you need both the base model and the GGUF variant appropriate for your VRAM.
Install the ComfyUI-Wan2 custom node through ComfyUI Manager. This adds video generation nodes specifically designed for the Wan model architecture.
Basic Video Generation Workflow:
- Load Wan2.2 GGUF model
- Text encoder for video prompt
- Image input (optional - for image-to-video)
- Wan2 sampler node
- Video decode node
- Save video
LoRA Integration for Character Consistency: Training a character LoRA allows you to generate videos featuring consistent characters - a major advancement for storytelling and content creation. For complete LoRA training strategies, see our LoRA training guide.
On 8GB hardware, you can use one character LoRA reliably. The workflow loads the base Wan2.2 Q5 model plus your trained character LoRA, staying just under 8GB total VRAM usage.
Training Character LoRAs:
Training Images | VRAM Required | Training Time | Result Quality |
---|---|---|---|
50-100 frames | 8GB | 2-4 hours | Good consistency |
100-200 frames | 10GB+ | 4-8 hours | Excellent consistency |
Custom scenes | Variable | Variable | Scene-dependent |
Optimization Tips for Video: Video generation produces multiple frames, multiplying VRAM requirements. Generate shorter clips on limited hardware - 2-3 seconds at 24fps rather than 5-second clips.
Reduce frame resolution to 512x512 or 480x480 for lower VRAM usage, then upscale the final video using traditional video upscaling tools.
Practical Video Workflow: Start with text-to-video generation to verify your setup works. Move to image-to-video for better control over composition. Finally, integrate LoRAs once you're comfortable with basic generation.
Process video projects in segments, generating multiple short clips rather than one long sequence. This prevents VRAM exhaustion and allows easier editing.
Live AI Art with ComfyUI + OBS Studio
Creating live AI art performances or streaming your generation process requires special optimization to handle both ComfyUI processing and streaming software simultaneously on limited VRAM.
Hardware Requirements for Streaming:
Component | Minimum | Recommended | Notes |
---|---|---|---|
GPU VRAM | 6GB | 8GB | Shared between ComfyUI and encoding |
System RAM | 16GB | 32GB | OBS buffering |
CPU | 6 cores | 8+ cores | Encoding assistance |
Storage | SSD | NVMe SSD | Fast model loading |
VRAM Budget Allocation: When running ComfyUI and OBS simultaneously, you need to allocate VRAM efficiently. Reserve 1-2GB for OBS encoding and system overhead, leaving 4-6GB for ComfyUI on an 8GB card.
Use NVENC hardware encoding in OBS rather than x264 software encoding - this shifts encoding work from VRAM to dedicated hardware encoders on the GPU.
ComfyUI Settings for Live Performance: Enable the --lowvram or --normalvram flag depending on your GPU. This forces more aggressive memory management at the cost of slightly slower generation.
Want to skip the complexity? Apatero gives you professional AI results instantly with no technical setup required.
Use Q3 or Q4 GGUF models exclusively when streaming - Q5 works on 8GB if you're careful, but Q4 provides better stability margins.
OBS Configuration for AI Art Streaming:
Setting | Value | Reason |
---|---|---|
Encoder | NVENC H.264 | Hardware encoding saves VRAM |
Preset | Quality | Balanced output/performance |
Rate Control | CBR | Stable streaming bandwidth |
Bitrate | 4500-6000 | HD quality without excess |
Resolution | 1920x1080 | Standard streaming |
FPS | 30 | Smooth video |
Window Capture Setup: Add ComfyUI as a window capture source in OBS. Enable hardware acceleration in your browser if using the web interface version of ComfyUI.
Create scenes that show your workflow construction alongside the generation output - viewers find the process as interesting as the results.
Performance Optimization: Close unnecessary background applications before starting your stream. Discord, browsers, and other GPU-accelerated apps steal precious VRAM.
Generate images at 512x512 during live streams, upscaling offline later for final versions. This keeps generation times reasonable for live audiences.
Interaction Strategies: Use ComfyUI's queue system to batch several prompts during talking segments, then display results during quieter generation moments.
Prepare workflows in advance so live streams focus on prompt engineering and parameter adjustment rather than building node graphs from scratch.
Backup Plans: Have pre-generated content ready in case VRAM limits crash your generation mid-stream. Switch to image review or discussion while restarting ComfyUI.
Consider running ComfyUI on a secondary computer if possible, with OBS on a dedicated streaming machine. This eliminates VRAM sharing entirely.
For professional streaming setups requiring rock-solid reliability, platforms like Apatero.com can handle generation on cloud infrastructure while you stream the interface, eliminating local VRAM constraints completely.
Advanced Low-VRAM Techniques and Workflows
Beyond basic GGUF optimization, several advanced techniques squeeze even more capability from limited VRAM.
Sequential Model Loading: Instead of loading multiple models simultaneously, create workflows that load, use, and unload models sequentially. This trades generation speed for VRAM efficiency.
The workflow loads checkpoint A, generates, saves to temporary storage, unloads A, loads checkpoint B, processes the temporary image, and generates the final output.
Tiled Processing Everywhere: Ultimate SD Upscale isn't the only node that benefits from tiling. ControlNet can process images in tiles. VAE encoding/decoding can use tiled approaches. Video generation can process frame segments.
Smart Caching Strategies:
Cache Type | VRAM Impact | Speed Impact | When to Use |
---|---|---|---|
Model caching | High VRAM | Faster | Multiple generations same model |
No caching | Low VRAM | Slower | Different models each generation |
Selective caching | Balanced | Moderate | Frequently used components only |
Precision Reduction: Beyond GGUF quantization, you can run entire workflows at fp16 or even fp8 precision using the --force-fp16 launch flag.
This affects all processing, not just model weights, providing another 20-30% VRAM reduction at minimal quality cost.
RAM Offloading: The --cpu flag forces some processing to system RAM instead of VRAM. This dramatically slows generation but allows running models that otherwise wouldn't fit.

Modern systems with 32GB+ of fast DDR5 RAM can use this technique surprisingly effectively for occasional high-memory workflows.
Batch Size Manipulation: Never use batch sizes greater than 1 on low-VRAM systems. While batching is more efficient on high-end hardware, it multiplies VRAM requirements proportionally on budget GPUs.
Workflow Segmentation:
Approach | VRAM Efficiency | Complexity | Best For |
---|---|---|---|
Monolithic workflow | Low | Simple | Abundant VRAM |
Two-stage workflow | Medium | Moderate | 6-8GB GPUs |
Multi-stage workflow | High | Complex | 4GB extreme optimization |
Microservices | Very high | Very complex | Distributed systems |
Resolution Ladder Technique: Generate at 256x256, upscale to 512x512, upscale to 1024x1024, optionally upscale to 2048x2048. Each stage uses minimal VRAM with cumulative quality improvements.
This approach produces better results than direct 4x upscaling while keeping memory usage constant.
Hardware-Specific Optimization Guides
Different GPUs have different optimization priorities. Here's targeted advice for common budget GPUs.
GTX 1650 / 1650 Super (4GB): Your primary limitation is VRAM capacity. Use Q2-Q3 GGUF models exclusively. Enable --lowvram always. Generate at 512x512 maximum base resolution.
Two-stage workflows are mandatory for anything above 512px. Video generation isn't practical - stick to image workflows.
GTX 1660 / 1660 Ti (6GB): Sweet spot for low-VRAM optimization. Q3-Q4 GGUF models work excellently. Standard ComfyUI flags sufficient. Generate at 640x768 comfortably.
Basic video generation possible with Wan2.2 Q3. Single LoRA support viable. Consider this the minimum for comprehensive ComfyUI usage.
RTX 3060 (12GB) / 3060 Ti (8GB):
Model | 3060 (12GB) | 3060 Ti (8GB) |
---|---|---|
FLUX Q5 | Comfortable | Tight fit |
FLUX Q8 | Possible | Not recommended |
Video Q5 | Yes + LoRA | Yes, single LoRA |
Multiple LoRAs | 2-3 simultaneously | 1-2 carefully |
Native resolution | 1024px+ | 768px comfortably |
AMD GPUs (6700 XT, 7600, etc.): ROCm support for AMD GPUs continues improving but requires additional setup. DirectML provides an alternative on Windows with easier installation but slower performance.
Budget 20-30% more VRAM headroom on AMD due to driver efficiency differences compared to NVIDIA CUDA.
Apple Silicon M1/M2 (Unified Memory): Unified memory architecture shares RAM and VRAM, allowing flexible allocation. An M1 Max with 32GB unified memory effectively has ~24GB available for AI workloads.
ComfyUI on Apple Silicon uses PyTorch MPS backend which continues improving but may not match CUDA optimization levels.
Laptop GPUs: Mobile GPUs often have reduced VRAM despite similar model numbers. A laptop RTX 3060 typically has 6GB vs desktop's 12GB.
Thermal throttling becomes a bigger concern than VRAM on laptops - ensure adequate cooling during generation sessions.
Troubleshooting Low-VRAM Workflows
Even with optimization, you'll occasionally hit VRAM limits. Here's how to diagnose and fix issues.
Common Error Messages:
Error | Cause | Solution |
---|---|---|
"CUDA out of memory" | VRAM exhausted | Reduce resolution, use lower quantization |
"RuntimeError: CUDA error" | VRAM fragmentation | Restart ComfyUI, clear cache |
"Model loading failed" | Insufficient VRAM | Use GGUF version, enable --lowvram |
Slow/hanging generation | Swapping to RAM | Close other apps, reduce batch size |
Diagnostic Process: Monitor VRAM usage with GPU-Z or Task Manager during generation. Identify exactly which workflow step exhausts memory.
Reduce that specific component - lower resolution, different model quantization, or split into sequential processing.
VRAM Leak Detection: If memory usage grows over time even after generations complete, you have a VRAM leak. Restart ComfyUI to clear accumulated memory.
Update custom nodes - leaks often originate from poorly written extensions that don't properly release GPU memory.
Performance Profiling:
Tool | Information | Use Case |
---|---|---|
GPU-Z | Real-time VRAM monitoring | Identifying usage spikes |
ComfyUI logs | Error details | Debugging crashes |
Windows Task Manager | Overall GPU usage | Detecting background interference |
nvidia-smi | Detailed NVIDIA stats | Advanced diagnostics |
When Optimization Isn't Enough: Some workflows genuinely require more VRAM than budget hardware provides. Complex video generation, multiple model compositing, and ultra-high resolution work have hard VRAM floors.
At that point, consider cloud platforms like Apatero.com that provide enterprise GPU access for specific projects without requiring hardware upgrades.
The Quality Question - Does Low-VRAM Compromise Results?
Let's address the elephant in the room: do these optimization techniques produce inferior results compared to high-end hardware?
Quantization Quality Impact:
Quantization | Visual Quality | Text Rendering | Fine Details | Overall Rating |
---|---|---|---|---|
Q2 | Noticeably reduced | Poor | Lost | 6/10 |
Q3 | Slightly reduced | Acceptable | Softened | 7.5/10 |
Q4 | Minimal reduction | Good | Mostly preserved | 8.5/10 |
Q5 | Nearly identical | Excellent | Preserved | 9.5/10 |
Q8 | Indistinguishable | Perfect | Perfect | 9.9/10 |
FP16 (baseline) | Reference | Perfect | Perfect | 10/10 |
Blind Test Results: In community blind tests, most users can't distinguish between Q5 GGUF outputs and fp16 outputs when viewed normally. Pixel-peeping reveals subtle differences in very fine details.
Q4 outputs remain extremely high quality with differences only visible in specific scenarios like small text or intricate patterns.
Two-Stage Generation Quality: Upscaling from 512px to 1024px using Ultimate SD Upscale produces results that match or exceed native 1024px generation in many cases.
The two-stage approach sometimes adds beneficial details during upscaling that native generation misses.
Video Generation Comparisons: Wan2.2 Q5 video quality is virtually indistinguishable from the fp16 version for most content. Motion smoothness and character consistency remain excellent.
Q3 video shows more noticeable quality reduction than Q3 image generation, making Q4-Q5 more important for video work.
Real-World Usage:
Use Case | Minimum Acceptable | Recommended | Professional |
---|---|---|---|
Personal projects | Q3 | Q4 | Q5 |
Social media | Q3 | Q4 | Q5 |
Print (small) | Q4 | Q5 | Q8/FP16 |
Print (large) | Q5 | Q8 | FP16 |
Client work | Q4 | Q5 | Q8/FP16 |
Commercial | Q5 | Q8 | FP16 |
When Quality Demands Trump VRAM: For critical professional work where absolute maximum quality is non-negotiable, cloud platforms with 24GB+ GPUs running fp16 models provide the uncompromised solution.
This doesn't mean low-VRAM approaches are unsuitable for professional work - it means understanding when the 95% quality of Q5 suffices versus when 100% is mandatory.
Conclusion - Low VRAM Isn't a Limitation Anymore
The techniques in this guide transform low-VRAM GPUs from frustrating limitations into capable creative tools. GGUF quantization, intelligent workflow design, and strategic optimization allow budget hardware to run workflows that seemed impossible just months ago.
Key Takeaways: GGUF Q5 models provide 95%+ quality at 25% VRAM usage. Two-stage generation with Ultimate SD Upscale produces high-resolution outputs on 4GB GPUs. Wan2.2 video generation with LoRAs works on 8GB hardware. Strategic workflow design matters more than raw VRAM capacity.
Choosing Your Path: If you have budget hardware and want to learn ComfyUI thoroughly, these optimization techniques unlock the full platform for you.
If you want immediate maximum-quality results without technical complexity, cloud platforms like Apatero.com provide enterprise GPUs and simplified workflows.
Many creators use both approaches - optimized local installation for learning and experimentation, cloud platform for production work and client projects.
What's Next: Start with basic GGUF optimization on simple workflows before attempting advanced techniques. Master two-stage generation before tackling video work. Join the ComfyUI community to share optimization discoveries and learn from other budget hardware users. Avoid common beginner mistakes that waste VRAM unnecessarily.
