Benchmark Performance

Performance Tips and Optimization

Inference Optimization

Flash Attention 2 (Recommended):

model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
    "E:/huggingface/qwen2.5-vl-32b-instruct",
    torch_dtype=torch.bfloat16,
    attn_implementation="flash_attention_2",  # 2-3x faster
    device_map="auto"
)

Quantization for Memory Efficiency:

# INT8 quantization (requires bitsandbytes)
from transformers import BitsAndBytesConfig

quantization_config = BitsAndBytesConfig(
    load_in_8bit=True,
    llm_int8_threshold=6.0
)

model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
    "E:/huggingface/qwen2.5-vl-32b-instruct",
    quantization_config=quantization_config,
    device_map="auto"
)

Extended Context (YaRN):

# For sequences > 32K tokens
model.config.rope_scaling = {
    "type": "yarn",
    "factor": 4.0,  # Extend to 128K tokens
    "original_max_position_embeddings": 32768
}

Best Practices

1. Image Resolution: Use 512-1024px for standard images, up to 2048px for detailed document parsing
2. Video Processing: Adjust FPS based on content (1-2 fps for static scenes, 5-10 fps for action)
3. Batch Size: Start with batch_size=1-2 for 80GB VRAM, scale based on sequence length
4. Temperature: Use 0.1-0.3 for factual tasks, 0.7-0.9 for creative generation
5. Max Tokens: Allocate 512 tokens for descriptions, 2048+ for detailed analysis or math

Memory Management

# Clear CUDA cache between runs
import torch
torch.cuda.empty_cache()

# Gradient checkpointing for fine-tuning
model.gradient_checkpointing_enable()

# CPU offloading for large batches
model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
    "E:/huggingface/qwen2.5-vl-32b-instruct",
    torch_dtype=torch.bfloat16,
    device_map="auto",
    offload_folder="offload",
    offload_state_dict=True
)

    --dtype bfloat16 \
    --max-model-len 32768 \
    --gpu-memory-utilization 0.9
