Beam 1.0 501B A23B
NewStandardReflection's open-weight reasoning model for coding and long-horizon agentic workflows.
501B-parameter sparse mixture-of-experts activating 23B per token, with a 1M-token context built for sustained tool use across large codebases.
▼
Beam 1.0 501B A23B is somewhat expensive at $1.00/M tokens input and $3.00/M tokens output. Cached input reads are priced at $0.10/M tokens, making repeated context cheaper. The model supports extended reasoning, a 1M context window.
