Bot Information¶

Creator: @togetherai

Description: Beam is Reflection's first open model: a Mixture-of-Experts, decoder-only transformer with roughly 501B total parameters and 23B active per token, built for the two workloads that lead frontier enterprise use, writing and maintaining code and executing long-horizon, multi-step tasks with tools. Beam is text-in, text-out by design: these workloads run on code, tool calls, logs, documents, and structured outputs, and every training decision targets depth in those domains. Reflection reports particularly strong reasoning efficiency, reaching solutions with fewer reasoning tokens and translating into higher throughput per GPU-hour. The model supports a context window of approximately 1M tokens, works out of the box with the runtimes, frameworks, and coding harnesses developers already use, and ships under the Apache 2.0 license. Beam is the first in a family, establishing the training recipe and developer surface that subsequent, larger Reflection models will build on. Available on Together AI.
