Reflection AI unveils Beam model with 501B parameters this month

Misha Laskin: Misha Laskin is the co-founder and CEO of Reflection AI. He leads efforts to build frontier open AI models through investments in pretraining and reinforcement learning. Laskin and his team are credited in the announcement for the development and upcoming full weights release of the Beam model. Reflection AI: Reflection AI is an artificial intelligence startup founded by former Google DeepMind researchers with a focus on developing open-weight models to make advanced intelligence open and accessible. The company positions its work as advancing Western capabilities in AI, particularly through efficient models for business and developer use. It is directly responsible for the introduction of Beam, its first open model emphasizing frontier reasoning efficiency, coding, and agentic tasks. Model Release: Full weights for the Beam model are scheduled for release later this month along with a model card and technical report. AI Competition: Beam is positioned to compete with leading open models from Chinese labs on reasoning efficiency and performance for business applications. Open AI Development: Reflection AI trained Beam end-to-end from scratch with a focus on advancing the Western open frontier in coding and agentic tasks.
