Reflection Launches Beam: an Efficient AI Model to Compete Globally

WHO:

TechCrunch - Reflection AI, a startup backed by Nvidia, has unveiled its first open-weight model called Beam.

Techmeme - Reflection AI is described as America's answer to open-source Chinese AI.

WHAT:

MarkTechPost - Beam is a 501B sparse Mixture-of-Experts model with 23B active parameters, specifically designed for coding and agentic workloads.

MarkTechPost - Reflection AI claims that Beam matches GLM-5.2 on reasoning while using 3 to 4 times less inference compute.

TechCrunch - Beam is said to rival GLM-5.2 in reasoning capabilities while requiring significantly less inference compute.

Techmeme - Beam excels at coding and agentic tasks and uses 3x-4x less compute than comparable models.

Techmeme - Beam is reported to be nearing the performance of Qwen 3.8-Max.

WHEN:

MarkTechPost - The Apache 2.0 weights for the Beam model are due to be released later in October 2026.

TechCrunch - The weights for the Beam model are due to be released this month.

WHY:

Techmeme - Reflection AI aims to compete with top Chinese open-weight models in the AI market.

HOW:

Techmeme - The model is designed to operate with lower compute requirements compared to its competitors.
