Ox Alpha Free on OpenRouter Sparks Mystery Over Its Builders

Anonymous providers began offering free access to a frontier coding model named Ox Alpha on OpenRouter, with OpenCode promoting a zero-retention, free-use route. The model handles text, images and video with a huge context window, but its origin remains opaque. Early benchmarks placed Ox Alpha around mid-range compared with GPT-5.6-sol, and there’s no public leaderboard. Independent fingerprinting hints at shared infrastructure with GLM-5.3, but identities are unconfirmed. Theories link Z.ai and other labs, though none are proven. OpenRouter says it merely routes requests and may retain prompts, while OpenCode claims zero retention, highlighting ongoing concerns about provenance and governance of anonymous AI models.
