Qwen3-235B users hunt sharper model

The hot take: this looks less like a raw-capability problem and more like a consistency problem. A model can be excellent on paper and still wobble when you ask it to stay on brief across chapters, style constraints, and repeated corrections.

• –Qwen3-235B-A22B-Instruct-2507 is still a heavyweight: 235B total parameters, 22B active, 262K native context, and strong public claims on instruction following, reasoning, and WritingBench.
• –The thread's visible reply jumps to Qwen3.5-397B-A17B, which lines up with Qwen's newer copy saying Qwen3.5 text capability beats Qwen3-235B-2507.
• –If free is the hard requirement, OpenRouter's current Qwen options make the tradeoff pretty clear: Qwen3 Next 80B A3B Instruct (free) is the steadier writing fit, while Qwen3.6 Plus Preview (free) is the newer, more ambitious preview with prompt/completion logging caveats.
• –OpenRouter's `openrouter/free` router is genuinely zero-cost, but it randomly selects among available free models, so it is useful for experimentation and not ideal for a repeatable book-writing workflow.
• –For book generation, long-horizon obedience matters more than benchmark spikes, so the "best" model is the one that keeps chapter tone and constraints intact.
