Beam: The Great American Open Model with ReflectionAI Co-Founder and CEO Misha Laskin

Open-weight AI models, exemplified by ReflectionAI's new 500B-parameter Beam, are on track to capture the majority of global token demand.

• Beam specs: Reflection AI's new open-weight model has 500B total parameters (23B active), trained on 6,000 GB300s for pre-training and 10,000+ GB300s for four weeks of RL.
• Reasoning efficiency: Beam is 3-4x more compute-efficient than same-capability-class models and up to 10x versus larger models, driven by large-scale RL atop a strong pre-trained base.
