Timeline of updates

  1. identified

    We have temporarily disabled custom code preprocessors across Braintrust Cloud while we work on fixing an ongoing issue with it. This may affect how conversations render in the Thread view, and the output of Topics facets and any scorers that rely on a custom preprocessor. Saved preprocessor code is unchanged and nothing has been deleted.

    Logging, querying, experiments, and all other functionality are unaffected, and no other regions are impacted. A fix is in progress and we expect to re-enable custom code preprocessors shortly.
