Key specs and claims: the model has 744B parameters (40B active) and matches or beats all frontier models (e.g. Fable and Astra) in multi-user long-horizon settings on the company's own evals, plus most external cooperation and multi-agent coding benchmarks. It targets multi-user collaboration and multi-agent coding workflows.
