Zhipu AI's GLM-5.2 — a 744B MoE model with 40B active parameters and 1M-token context — had its MIT-licensed weights released on HuggingFace around June 17, with Axios publishing on June 25 that security researchers found the model matches US frontier models on cybersecurity benchmarks. GLM-5.2 scores 62.1 on SWE-bench Pro, ranks second on Code Arena, and is priced at roughly $1.40/million input tokens versus GPT-5.5 at $5.

Why it matters

The combination of frontier-level coding capability, MIT licensing allowing unrestricted commercial use, and cost roughly one-sixth of GPT-5.5 makes GLM-5.2 the most cost-disruptive open-weight coding model currently available; the security community is evaluating its dual-use potential.

Importance: 4/5

MIT-licensed frontier-level coding at 1/6 the price of GPT-5.5 — most cost-disruptive open-weight coding model yet, with active security implications
