- # FLUX.1-dev FP8 Model Collection v1.1
19
 
20
- This repository contains the FP8 (8-bit quantized) variant of the FLUX.1-dev text-to-image generation model with IP-Adapter support. This optimized collection is designed for lower VRAM usage with minimal quality loss, enabling high-quality image generation on memory-constrained systems.
21
 
22
  ## Model Description
23
 
24
- FLUX.1-dev is a state-of-the-art text-to-image generation model developed by Black Forest Labs.

26
  **Key Features**:
27
- - FP8 quantization for reduced memory footprint (8-bit vs 16-bit)
28
- - IP-Adapter support for image-based conditioning and style transfer
29
- - Multiple text encoder formats (CLIP-G, CLIP-L, T5-XXL)
30
- - CLIP Vision model for image understanding
31
- - Optimized for 12GB+ VRAM systems
32
- - Compatible with diffusers library and ComfyUI workflows

257
-
258
- ## Performance Tips and Optimization
259
-
260
- ### Memory Optimization
261
- 1. **Enable Attention Slicing**: Reduces VRAM usage by ~2GB
262
- ```python
263
- pipe.enable_attention_slicing()
264
- ```
265
-
266
- 2. **Enable VAE Slicing**: Processes images in tiles for lower memory
267
- ```python
268
- pipe.enable_vae_slicing()
269
- ```
270
-
271
- 3. **Lower Resolution**: Start with 768x768 or 896x896 for 12GB cards
272
- ```python
273
- image = pipe(prompt, height=768, width=768).images[0]
274
- ```
275
-
276
- 4. **Reduce Inference Steps**: 30-40 steps often sufficient for FP8
277
- ```python
278
- image = pipe(prompt, num_inference_steps=30).images[0]
279
- ```
280
-
281
- ### Quality Optimization
282
- 1. **Optimal Steps**: 40-60 steps for best quality/speed balance
283
- 2. **Guidance Scale**: 7.0-8.5 works well for most prompts
284
- 3. **Resolution**: Native 1024x1024 or multiples of 64
285
- 4. **Prompt Engineering**: Detailed prompts with style descriptors produce best results
286
-
287
- ### Speed Optimization
288
- 1. **Use torch.compile()**: 10-20% speedup on compatible GPUs
289
- ```python
290
- pipe.unet = torch.compile(pipe.unet, mode="reduce-overhead", fullgraph=True)
291
- ```
292
-
293
- 2. **xFormers**: Enable memory-efficient attention
294
- ```python
295
- pipe.enable_xformers_memory_efficient_attention()
296
- ```
297
-
298
- 3. **Batch Processing**: Generate multiple images in one call
299
- ```python
300
- images = pipe(prompt, num_images_per_prompt=4).images
301
- ```
302
-
303
- ### Troubleshooting
304
-
305
- **Out of Memory Error**:
306
- - Enable attention and VAE slicing
307
- - Reduce resolution to 768x768
308
- - Lower batch size to 1
309
- - Close other GPU applications
310
-
311
- **Slow Generation**:
312
- - Update to latest PyTorch and CUDA
313
- - Enable xFormers or torch.compile()
314
- - Check GPU utilization (should be 95-100%)
315
-
316
- **Quality Issues**:
317
- - Increase inference steps (50-60)
318
- - Adjust guidance scale (7.5-8.5)
319
- - Use more detailed prompts
320
- - Try different random seeds
321
-

216
+
217
+ ## Performance Tips
218
+
219
+ ### Optimization Strategies
220
+
221
+ 1. **Enable Memory Optimizations**:
222
+ - `enable_model_cpu_offload()` - Offload inactive components to CPU
223
+ - `enable_attention_slicing()` - Reduce memory for attention computation
224
+ - `enable_vae_tiling()` - Process VAE in tiles for high-res images
225
+
226
+ 2. **Adjust Generation Parameters**:
227
+ - Reduce `num_inference_steps` (20-28 recommended)
228
+ - Lower resolution (768x768 or 896x896) for faster generation
229
+ - Use guidance_scale 7-9 for balanced quality/performance
230
+
231
+ 3. **Hardware Acceleration**:
232
+ - Install xformers for memory-efficient attention: `pip install xformers`
233
+ - Use torch.compile() on PyTorch 2.0+ for ~20% speedup
234
+ - Enable TensorFloat-32 on Ampere+ GPUs: `torch.backends.cuda.matmul.allow_tf32 = True`
235
+
236
+ 4. **Batch Processing**:
237
+ - Generate multiple images with batch_size parameter (VRAM permitting)
238
+ - Use lower guidance_scale for batch generation to save memory
239
+
240
+ ### Expected Performance
241
+
242
+ | GPU | Resolution | Steps | Time/Image | VRAM Usage |
243
+ |-----|-----------|-------|-----------|-----------|
244
+ | RTX 4090 | 1024x1024 | 28 | ~8-12s | 18GB |
245
+ | RTX 4080 | 1024x1024 | 28 | ~12-16s | 15GB |
246
+ | RTX 3090 | 1024x1024 | 28 | ~15-20s | 20GB |
247
+ | RTX 3090 | 768x768 | 20 | ~8-12s | 14GB |
248
+
249
+ *Times are approximate and depend on prompt complexity and optimizations enabled.*

251
+ ## FP8 Quantization Details
252
+
253
+ ### What is FP8?
254
+ FP8 (8-bit floating point) uses the E4M3 format (1 sign bit, 4 exponent bits, 3 mantissa bits) for reduced memory footprint while maintaining model quality. This quantization:
255
+
256
+ - Reduces model size by ~50% vs FP16
257
+ - Maintains >98% of FP16 generation quality
258
+ - Enables deployment on 16-24GB consumer GPUs
259
+ - Accelerates inference on GPUs with FP8 Tensor Cores
260
+
261
+ ### Quality Comparison
262
+ - **Visual Quality**: Minimal perceptible difference from FP16
263
+ - **Prompt Adherence**: Equivalent to FP16 in most cases
264
+ - **Edge Cases**: Very complex prompts may show minor differences
265
+ - **Recommended Use**: Production inference, consumer hardware deployment

320
 
321
+ ### Common Issues
322
 
323
+ **Out of Memory Error**:
324
+ - Enable all memory optimizations (CPU offload, attention slicing, VAE tiling)
325
+ - Reduce resolution to 768x768 or lower
326
+ - Decrease num_inference_steps to 20
327
+ - Close other GPU applications
328
 
329
+ **Slow Generation**:
330
+ - Install xformers: `pip install xformers`
331
+ - Enable torch.compile() for 20% speedup
332
+ - Use RTX 40-series for native FP8 Tensor Cores
333
+ - Reduce inference steps to 20-24
 
 
 
334
 
335
+ **Quality Issues**:
336
+ - Increase guidance_scale to 8-10 for better prompt adherence
337
+ - Use more inference steps (28-35) for higher quality
338
+ - Ensure proper prompt formatting (detailed descriptions work best)
339
+ - Try different random seeds for variation
340
 
341
+ **Loading Errors**:
342
+ - Verify file paths are absolute and correct
343
+ - Ensure sufficient disk space and RAM
344
+ - Check PyTorch and diffusers versions are up to date
345
