Description
[!CAUTION] Breaking Changes
- Unknown content blocks now return the scope as
model_nameandprovider_nameinstead of the fully-qualifiedmodel_provider_name.
[!WARNING] Planned Deprecations
- The TensorZero UI now reads the configuration from the gateway (instead of reading directly from the filesystem). The environment variables
TENSORZERO_UI_CONFIG_PATHandTENSORZERO_UI_DEFAULT_CONFIGare deprecated and ignored. You no longer need to mount the configuration onto the UI container.- Use
model_nameandprovider_nameto scope provider tools (e.g. OpenAI Responses API web search) instead ofmodel_provider_name. The deprecated name is still accepted in the API.
Bug Fixes
- Fix a regression in the "Try with..." modal in the UI that disregarded some parameters (e.g.
allowed_tools). - Fix a regression in
allowed_toolswhen using custom display names for tools. - Fix an edge case when using both
allowed_toolsandtool_choiceparameters with GCP Vertex AI Gemini.
New Features
- Support free-form search and filtering (e.g. by tags, metrics) the inference and datapoint tables in the UI.
- Support creating datapoints from scratch in the UI.
- Support editing TensorZero API key descriptions in the UI (thanks @nicoestrada!).
- Support editing any kind of datapoint input and output in the UI.
- Support peeking at inferences in the episode detail page in the UI (thanks @BrianLi23!).
- Support cloning datapoints in the UI.
- Optimize the rendering performance of the code editor in the UI.
- Make
mime_typeoptional for base64 file inputs (now inferred from magic bytes when not provided).
& multiple under-the-hood and UI improvements
