Cloudflare Launches First Stealth Model Union Alpha, Blending Multiple LLMs Per Request
ritakozlov · x · 2026-09-17
Cloudflare put its first-ever 'stealth' model, Union Alpha, on the Cloudflare AI Gateway. It's a blended model that calls multiple LLMs in parallel per request, synthesizes one answer, and supports text and vision inputs through a single API.
Cloudflare touts it as the sweet spot for price/performance and invites users to try it. Docs show standard chat-completions-style usage via Workers AI or curl with model name stealth/union-alpha.
