Mystery Model 'OxAlpha' Sparks Tech Fingerprint Hunt: Suspected Zhipu or Google
量子位 · wechat · 2026-08-23
The anonymous model "OxAlpha" has gone viral for its 1M context window and free tier, triggering a community-wide investigation into its origin.
Evidence Points to Zhipu: Tests reveal OxAlpha's token counts align with GLM-5.3 (with a fixed offset) and its video token budget matches GLM-5V-Turbo. Traces of "trained by Z.ai" were also allegedly found. History supports this: OpenRouter's previous anonymous model, PonyAlpha, was revealed to be an early GLM-5.
Google Suspicions Rise: OxAlpha's specs (1M context, native multimodal, long-horizon agents) mirror the delayed Gemini 3.5 Pro. Ambiguous social media posts from DeepMind employees have fueled rumors linking it to Google.
Mixed Benchmark Results: In a small 10-task coding test, OxAlpha achieved an 80% success rate, beating GPT-4o. However, other tests by Abacus.AI and Wharton professors suggest it performs only on par with older generation models.
