Qwen3.8-27b-Terse-Coder-GGUF

GGUF builds of Shockem/Qwen3.8-27b-Terse-Coder (round 8, final) — a fine-tune of Qwen/Qwen3.8-27B with ~1/10 the chain-of-thought reasoning tokens on coding tasks and correctness preserved.

Quant spread (Q4_K_M smoke-tested on llama.cpp — correct code generation, reasoning parsing, ~22 tok/s on 2× RTX 5060 Ti):

File Size Notes
Qwen3.8-27b-Terse-Coder.Q4_K_M.gguf ~16.8G Balanced quality/speed — the default pick
Qwen3.8-27b-Terse-Coder.Q5_K_M.gguf ~19.5G
Qwen3.8-27b-Terse-Coder.Q6_K.gguf ~22.4G
Qwen3.8-27b-Terse-Coder.Q8_0.gguf ~29.0G Near-lossless
Qwen3.8-27b-Terse-Coder.mmproj-f16.gguf ~0.9G Vision projector (required for images)
Qwen3.8-27b-Terse-Coder.mmproj-Q8_0.gguf ~0.6G Vision projector, quantized

Usage (llama.cpp server): Chat template: use Shockem/froggeric-terse-coder (based on froggeric/Qwen-Fixed-Chat-Templates) (also bundled here as chat_template.jinja) — it carries the anti-rumination tool rules the model was evaluated with; serving without it changes agentic behavior.

llama-server -m Qwen3.8-27b-Terse-Coder.Q4_K_M.gguf \
  --mmproj Qwen3.8-27b-Terse-Coder.mmproj-f16.gguf \

The MTP draft layer is included in the GGUF but unused by llama.cpp (harmless warnings about unused blk.N.nextn.* tensors are expected); speculative decoding is a vLLM-side feature. Behavior/quality reference: HE+ 91.5 / MBPP+ 79.4 / GSM8K 98.5 / GPQA 79.8 on the source repo (vLLM measurements; GGUF Q4_K_M verified by smoke test only — validate quality on your own hardware before relying on it).
