Qwen3.8 Max, free for everyone this week
Alibaba's 1M-token-context flagship joins the model menu — and now through July 27 it costs nothing, on every account.
Qwen3.8 Max is Alibaba's new flagship: a one-million-token context window and deep reasoning that is always on, at full depth, before every step it takes. Like Kimi K3 before it, the model refuses to answer without thinking first — there is no dial to turn it down.
That fits what a Clusy session is. When the agent plans an experiment, writes the cells, runs them, and reads the results, the transcript grows fast — data schemas, training logs, tracebacks, the three branches you tried before the one that worked. A model that can hold all of that at once, and reasons about it before each action, spends less of a long run re-deriving what it already knew.
Free for launch week
Through launch week, Qwen3.8 Max is free for everyone on Clusy — every account, including free ones — and Qwen turns don't draw down your usage allowance. Open the model selector, pick Qwen3.8 Max, and give it a real problem: a fine-tune, a messy dataset, a paper you want reproduced.
Update (July 25): the free window has been extended through the weekend. It now ends on July 27 at 00:00 UTC (previously July 26). After that, Qwen3.8 Max stays in the lineup on paid plans, alongside Kimi K3 and the other open models.
The model is days old and in demand at the source; if a turn fails at peak, Clusy retries and tells you.
