Introducing Beam: Reflection’s 501B open-weight model

We build open models for everyone to access, use, and build on

We’re making intelligence open and accessible to all

We build open models for everyone to access, use, and build on

Solutions

We are building a full AI stack around our open models

Open-weight models

We develop models you can inspect, fine-tune, and deploy on your terms. Rigorously tested for safety and built for efficient performance

Open source software

We develop open-source software for building an AI stack you can control and audit, including easily deployable containers, customization recipes, and agentic harnesses

Infrastructure

We serve open models through our API platform or allow you to deploy them in your own environment, from private cloud to on-prem, air-gapped, and edge infrastructure

Solutions

Our forward-deployed team works alongside your teams from ideation through application design, development, and deployment to deliver measurable business outcomes

Open intelligence

Build with Beam

Our first open-weight model is a 501B MoE model, built for coding, reasoning, and agentic workloads.

The most important technology in history has been built in the open

Our convictions

The most important technology in history has been built in the open

The platforms that shaped the modern world were built through shared discovery, broad participation, and contributions from people who could see, improve, and build on each other's work. Reflection was built on the same belief.

  • Open science powers progress

    Open systems drive faster innovation, better outcomes, and broader participation in the future of AI. When intelligence is shared, progress moves faster and benefits more people.

  • Safety demands scrutiny

    When models are closed, safety research is bottlenecked by a few labs. When models are open, researchers can probe for risks and make these systems safer.

  • Power to the builders

    Researchers, developers, and organizations should be able to deploy, govern, and evolve AI systems on their own terms. AI is a powerful technology and, rather than concentrating it in the hands of a few, it should be diffused.

Build the future of open intelligence

Builders advancing intelligence that belongs to everyone. Working at Reflection means building from the ground up alongside some of the best researchers, engineers, and operators in AI.
