What changed

Reflection AI is officially unveiling Beam, its first frontier, open-weight AI model. Reflection’s announcement confirms reporting from Axios over the weekend that the startup was close to a launch. Reflection says it will release Beam’s weights and full technical details this month, with distribution through hyperscalers and neoclouds and integrations across open source libraries at launch.

Why it matters

A concrete addition to Practical AI: Tools, Models & Frameworks: it changes what's available to builders today rather than being general commentary.
