Z.ai releases GLM-5.2 open weights with a 1M-token context under MIT
Z.ai released GLM-5.2, a roughly 753B-parameter successor to GLM-5.1 with a 1M-token context window and multiple thinking-effort levels, under an MIT license without regional restrictions. A new IndexShare sparse-attention design reduces per-token compute at long context. For practitioners, it gave a permissive, self-hostable model built for long-horizon coding tasks; Hugging Face later reported using it during its July incident response.
