New

  • Gateway: added a native OpenRouter chat completions endpoint, with reasoning and provider preferences passed through correctly.
  • Agent search: Respan Agent can now use full-text search to find relevant information.

Improved

  • Behaviors: added LLM judging to improve behavior classification and analysis.
  • Experiments: experiment details now present grader names, outcomes, scores, latency, cost, tokens, and errors more clearly while hiding unnecessary metadata.
  • Experiment performance: added early row previews, lighter list responses, and compression for large experiment APIs so results appear sooner and transfer less data.
  • Model discovery: improved recommended-model ordering, BYOK availability filtering, and model-detail layouts to make suitable models easier to find and compare.
  • Model catalog: compressed model catalog responses to reduce loading time.
  • Workflows: optimized workflow execution paths for substantially faster processing.
  • Monitors: simplified monitor rendering for clearer, more consistent notifications.

Fixed

  • Log exports: large exports now use stable ordering, recover from storage interruptions, and avoid silently dropping rows. Failed or incomplete exports also report accurate progress and no longer provide untrustworthy downloads.
  • Reliability: brief cache interruptions no longer restart otherwise healthy web servers or turn into avoidable request failures.
  • Models: plain and provider-prefixed model names now resolve to the same catalog entry and behave consistently.
  • Spans: model icons remain readable when the Model column is narrow.
  • Lists: invalid sorting options now fall back safely instead of causing server errors.
  • Dashboard metrics: fixed organization-filtered quantile requests that could return server errors.
