# Reflection’s Beam trails top open models on coding tests but claims lower inference compute > Source: > Published: 2026-10-06 05:22:28+00:00 Reflection AI has built Beam, a 501-billion-parameter open-weight model for coding and agent tasks, and plans to publish the weights under an Apache 2.0 license later this month. Open-weight means developers can download the trained model and run it on their own hardware. Beam uses a mixture-of-experts design, so 23 billion of its parameters fire for any given token, which keeps the cost of each answer down. Beam does not lead the open field on … [More](https://www.helpnetsecurity.com/2026/10/06/reflections-beam-trails-top-open-models-on-coding-tests-but-claims-lower-inference-compute/) The post [Reflection’s Beam trails top open models on coding tests but claims lower inference compute](https://www.helpnetsecurity.com/2026/10/06/reflections-beam-trails-top-open-models-on-coding-tests-but-claims-lower-inference-compute/) appeared first on [Help Net Security](https://www.helpnetsecurity.com).
