Reflection positions itself as a US open weights AI lab, as an alternative to both Chinese labs and the proprietary models of leading US labs. Reflection reportedly plans to use revenue sharing licenses with its large language models (LLMs). In October, Reflection announced its first LLM, Beam, with 501 billion parameters.
Reflection's work combines large language model training, reinforcement learning, agentic AI, and software engineering automation. The company says it is developing open foundation models and advancing both pre-training and post-training systems, with an emphasis on reinforcement learning at scale.
In October 2025, Reflection said it had built a large-scale large language model and reinforcement learning platform capable of training mixture of experts models at frontier scale, first applying the approach to autonomous coding and later expanding it toward general agentic reasoning.
Reflection's first product was Asimov, a code-comprehension agent for engineering teams. Wired reported in July 2025 that Asimov reads source code, emails, Slack messages, project updates and documentation to answer questions about how software systems are built.
On 5 October 2026 Reflection announced its first model, Beam, with 501 billion parameters, 23 billion active. It was positioned as a “workhorse” that performs better than other Western open models at a much lower cost of inferencecompute. Beam performed similarly in benchmarks to GLM 5.2, a previous-generation open model by Chinese firm Z.ai. As of 10 October, the model remains in early access.
Funding and partnerships
In March 2025, Reflection emerged from stealth with $130 million in financing, including a $25 million seed round and a $105 million Series A round. The financing valued the company at about $545 million.
In June 2026, Axios reported that Reflection had signed a compute agreement with SpaceXAI for access to chips and hardware from the SpaceXColossus data center. Under the agreement, Reflection would pay $150 million per month starting July 1, 2026, through 2029, after an initial ramp period.
Following talks with investor JPMorgan Chase, Reflection was valued at $25 billion as of June 2026.
In July 2026, Reflection and Nebius signed an agreement for over $1 billion in computing power, allowing Reflection access to Nvidia's GB300 chips through 2029.
