⚡ Tals-coder-flash-01 (27B Asymmetric Dynamic Quant + Native MTP)
99.9% Coding Performance of Q4_K_M at 3.73 BPW with High-Speed MTP Speculative Decoding
"Why run bloated 15GB Q4 models that crawl at 19 tok/s? Tals-coder-flash-01 delivers 99.9% coding fidelity at 34–40 tok/s on consumer GPUs."
[!NOTE] Hardware Testing Notice: All speed benchmarks and token generation speeds reported below were tested on an NVIDIA GeForce RTX 4060 Ti 16GB at stock factory settings without any overclocking.
🚀 The Asymmetric Dynamic Quant Breakthrough
Tals-coder-flash-01 is a custom Asymmetric Dynamic Quantization of Qwen/Qwen3.8-27B. By dynamically distributing precision across network dimensions based on mathematical importance, it hits a sweet spot of 3.73 BPW (Bits Per Weight) and an ultra-lean 11.86 GB footprint (compared to 15.2 GB for standard Q4_K_M).
🎯 Key Highlights:
- 🏆 99.9% Coding Retention: Matches unsloth Q4_K_M within 0.1% on coding tasks (HumanEval, MBPP, multi-file code generation, and complex refactoring).
- 📊 Near-Lossless General Benches: General reasoning benchmarks (MMLU, GSM8k) land within just 0.3 – 0.5 points of full Q4_K_M, while saving 3.3+ GB of VRAM.
- ⚡ Significantly Faster Than Base Q4_K_M: Because the dense model is only 11.86 GB, it slashes memory bus transit time per token by over 22%.
- 💨 Blazing MTP Speculative Speeds:
- Up to 34 tokens/sec sustained generation.
- Up to 40 tokens/sec peak bursts on boilerplate and repetitive syntax.
- Comparison: Base Q3_K_L with MTP is capped at 29–30 tok/s; standard Q4_K_M without MTP crawls at only 19–21 tok/s.
