Today, Reflection released Beam , its first open-weight model built to give developers, researchers, and enterprises open control and customization for frontier software engineering and long-horizon agentic tasks. Released under a permissive Apache 2.0 license with BF16 , FP8 , and NVFP4 checkpoints available at launch, Beam sets a new standard for inference efficiency in the 500B-parameter class by solving complex reasoning and coding problems with 3x to 4x higher reasoning compute efficiency than comparable open models. Alongside today’s release, Google Cloud is announcing day 0 support and
