This is historical material. Use the current Managed Research, Research Factory, and GEPA/GELO pages for product decisions.

TL;DR

  • LocalAPI definitions are simpler and more readable, with less boilerplate.
  • Rollouts are trace-first (v3 trace + rewards), retiring canonical step/trajectory payloads.
  • Docs, validators, and examples now align on LocalAPI naming and trace correlation IDs.

LocalAPI Definition Simplified

LocalAPI apps now center on a smaller core: a clear spec, explicit dataset/task info, and a trace-only rollout response. The result is fewer moving parts and a much more straightforward path to adding new LocalAPI services.

Trace-First Rollouts

Rollout responses now prioritize v3 traces and rewards. Training and evaluation pipelines read trace event history directly, removing the need to build and maintain canonical step/trajectory payloads.

Cleaner Examples & Validation

Updated examples and docs reflect the new LocalAPI shape, while validators enforce trace correlation IDs and required secrets so issues are caught early.
