GLM 5.2 Spotted in Google Antigravity Binary

A model reference for GLM 5.2 has been found inside Google's Antigravity developer tool. The find hints that Zhipu AI's next flagship could land in Antigravity before it officially launches.

What Happened

An audit of the antigravity-cli 1.1.24 binary uncovered a new model reference labeled glm-5.2-fp8. GLM 5.2 has not been publicly announced yet, so its presence in the binary suggests an early partner integration. Google's Antigravity already gives developers access to Anthropic models like Sonnet and Opus. Adding GLM 5.2 would make it a multi-model hub. The FP8 tag points to high inference throughput, optimized for speed and a lower memory footprint.

Why It Matters

If this leak holds, developers could test GLM 5.2 inside Antigravity without waiting for Zhipu AI's own release. The integration would put a third major model family inside one developer stack.
