👁 Benchmark
A 9B Qwen3.5 merge tuned for SWE-agent style workflows: multi-turn tool use, debugging, structured code generation, and reasoning-heavy instruction following. The model keeps MTP draft layers for speculative decoding in llama.cpp.

Notes
| Topic | Note |
|---|---|
| Benchmark style | Local API runs with fixed prompts and deterministic decoding |
| Output handling | Some backends split content and reasoning_content; clients should merge carefully if needed |
| Safety | Generated code should be reviewed before execution |
| SWE-bench | This page describes the project’s local benchmark suite, not the SWE-bench Verified leaderboard |
