Reflection AI Unveils Beam to Challenge Closed US and Open Chinese Models
Reflection AI has launched Beam, a 501-billion-parameter open-weight model designed to compete with Chinese open systems and closed US giants like Anthropic and OpenAI. Backed by Nvidia, the startup aims to offer enterprises a cheaper, customizable alternative that avoids the security risks of Chinese models and the high costs of closed APIs. While Beam is currently in safety testing, its release signals a shift toward open-weight AI in the West, potentially disrupting the revenue models of major closed labs. Concurrently, Mistral is preparing to release its own massive open-weight model, indicating a broader Western effort to narrow the gap with Chinese open AI.
