Qwen 2.5 3B — fraQtl KV Cache Optimized
KV cache optimized with fraQtl — 3.5x less KV cache memory during inference.
Note: The model file size is the same as the original (~6.2GB). The optimization modifies V projection weights so that at inference time, the KV cache uses 3.5x less GPU memory. The savings happen at runtime, not at download.
| Metric | Value |
|---|---|
| Original | Qwen/Qwen2.5-3B |
| File size | Same as original (~6.2GB) |
| KV cache memory | 3.5x less at runtime |
| PPL before | 14.4222 |
| PPL after | 14.7302 |
| Delta | +0.308 (weight-level) |
| Config | k=32, INT3 |
Usage
from transformers import AutoModelForCausalLM, AutoTokenizer
model = AutoModelForCausalLM.from_pretrained("fraQtl/Qwen-2.5-3B-compressed")
tokenizer = AutoTokenizer.from_pretrained("fraQtl/Qwen-2.5-3B-compressed")
# KV cache uses 3.5x less memory during inference.
Runtime Compression
Our runtime compression achieves +0.01 PPL — 30x better than this weight-level demo. Contact us for integration.
