Reflection Debuts Beam, an Open-Weight AI Model to Rival Chinese Models at Lower Compute Cost
Reflection AI’s first model, Beam, is a 501-billion-parameter mixture-of-experts model with 23 billion active parameters and Apache 2.0 weights due this month. We count its wins and losses against seven open rivals in Reflection’s own table, unpack the 3-4x compute claim, and work out what it takes to run.
