Cloudflare's Workers AI docs revealed its first stealth model, Union Alpha, described as a multimodal model for research, coding, and agentic workflows with frontier-level general performance.
- Already callable via the API (stealth/union-alpha), with full usage examples in the docs.
- The community is fingerprinting its true identity; guesses point to GLM 4.5, though others argue it's a single model rather than a router — the official account replied "keep digging!", suggesting the guess hasn't hit yet.
