Alternatives

If Jeff is not the right fit, consider these alternatives:

  • Jev: TypeSafe's hosted System One model when you want the original API and larger reasoning capacity.
  • LangGraph: Better when the missing piece is orchestration around several decision calls rather than the classifier itself.
  • MiroFish: A different local-first approach, aimed at multi-agent simulation rather than classification.
  • Buzz: When the missing piece is a workspace for agents, not a decision model.
