Qwen3.5 distills Opus reasoning for agents

The interesting part here is not just the model name, it’s the product thesis: “Opus-like” behavior in a locally runnable Qwen fine-tune. If the claims hold up, this is exactly the kind of model that can make local agents feel less brittle and more useful.

• –The model card explicitly targets coding agents like Claude Code and OpenCode, and claims better tool-calling stability, native `developer` role support, and fewer hidden-thinking stalls.
• –Community testing in the Reddit thread is cautiously positive: one user says v1 is slightly nicer for short tasks, but v2 is better for actual agent work because it wastes less output budget and recovers more cleanly from tool loops.
• –This looks more like a practical agent-tuning story than a pure benchmark flex. The selling point is smoother autonomy, not just raw intelligence.
• –The provenance is the eyebrow-raiser: “distilled from Claude” will attract attention and skepticism, so expect both legal/ethical debate and a lot of scrutiny around how much of the value is style transfer versus real capability gain.
• –For developers, the main takeaway is simple: if you want a local reasoning model for long-running tool use, this is worth watching, but treat it like a fast-moving preview rather than a settled default.
