the take

The strongest open-weights model on the independent index, MIT-licensed, and a genuine problem for the closed labs. Off the board here only because Z.ai skipped SWE-bench Verified, MMLU-Pro and LiveCodeBench, so I cannot place it fairly against the rest.

Not ranked: Z.ai (Zhipu AI) doesn't publish enough comparable public benchmarks to place it fairly. How ranking works.
