Reflection AI unveiled Beam, a 501-billion-parameter open-weight model designed to compete with Chinese AI systems while requiring lower computational resources for inference. The mixture-of-experts model activates 23 billion parameters and targets coding and agentic workloads. While early testing showed Beam trailing top open-source models on coding benchmarks, Reflection positioned it as the most capable open-weight model developed outside China, marking a strategic play in the intensifying U.S.-China AI competition.
