Quality check

Verified via vLLM (greedy): factual recall, multi-step reasoning (correct algebra on classic trap questions), and code generation with Tess-4's characteristic verification-style thinking all intact — including weight-scaled reasoning (empty think block on trivial questions).

Usage (vLLM)

bash
vllm serve migtissera/Tess-4-27B-NVFP4 --trust-remote-code

On hybrid-arch builds you may need --max-num-seqs 64 (mamba cache blocks). For agentic/tool use add: --enable-auto-tool-choice --tool-call-parser hermes --reasoning-parser qwen3.

Pro tip: pair with the EAGLE-3 draft for compound speedup — quantization and speculative decoding stack.
