Beam open model lets teams own and customize AI
Hugging Face: Welcome Beam: a 501B open model you can own, customize, and scale
Open-source alternatives to proprietary AI systems could shift control over large language models from commercial labs to individual organizations and researchers.
Get smart on it
Beam is an open-source artificial intelligence model with 501 billion parameters that can process text and maintain context across very long conversations. It is designed for coding and agentic tasks, and is released under a license that allows teams to own, customize, and run it on their own hardware. The model uses a mixture-of-experts architecture, meaning only a portion of its network activates per token, allowing it to run at the speed of a smaller model while retaining the capacity of a larger one. Support for running and customizing Beam is available through established machine learning libraries, with the model released alongside recipes for fine-tuning and reinforcement learning applications.

OpenAI will reportedly ship at least one model this year but its flagship still needs alignment work
OpenAI is racing to finish its next flagship model, which uses the same looped transformer technique as Astra to boost math and coding performance. The tradeoff is that looping makes safety monitoring harder. Microsoft accidentally revealed details about how the technique works on a public page. Whether or not the flagship is ready in time, employees say one or two new models will likely ship by year's end. The article OpenAI will reportedly ship at least one model this year but its fla
