Reflection’s Beam trails top open models on coding tests but claims lower inference compute

Reflection artificial intelligence (AI) has released Beam, an open-weight model with 501 billion parameters designed for coding and agent applications. The model uses a mixture-of-experts approach to reduce inference costs while maintaining competitive performance on coding benchmarks, with weights to be published under an Apache 2.0 license.

Why it matters: Developers deploying open-source coding models can evaluate whether Beam's lower inference costs justify adoption despite trailing performance on some benchmarks compared to proprietary alternatives.
