It seem this news is "outdated" as it's from Jul 8 and might picked up confusing this model with yesterday Qwen 3 coder 405B release that is different in specs.
I initially thought this was about the Qwen release from two days ago, Qwen3-235B-A22B-Instruct-2507 - https://simonwillison.net/2025/Jul/22/qwen3-235b-a22b-instru... - but that's a no-reasoning model and the Cerebras announcement talks about reasoning, which tipped me off that this was Qwen's Qwen3-235B-A22B from April.
