The U.S. has a new horse in the race to build the best open-source AI model, a competition China is currently dominating, with popular models such as Kimi K3 from Moonshot and DeepSeek’s V4.
Reflection, a New York City-based AI company, today unveiled its first model, called Beam. It “advances the frontier for the Western open ecosystem,” the company told Fortune. The company said that in benchmark tests it conducted Beam achieved scores similar to GLM-5.2, an open model from Beijing-based Z.ai that was released back in July. That model was succeeded by GLM-5.3, which Z.ai debuted in August.
