Description
[!CAUTION] Breaking Changes
- Moving forward, explicit
tensorzero::paramswill take precedence over conflicting native parameters when using the OpenAI-compatible inference endpoint.
[!WARNING] Planned Deprecations
- Rename
json_mode="implicit_tool"tojson_mode="tool".- Set
model_nameand optionallyprovider_nameinstead ofmodel_provider_nameinextra_bodyandextra_headersobjects supplied at inference time. Alternatively, don't include a scope filter at all.
New Features
- Support Anthropic's Beta Structured Outputs feature natively (
beta_structured_outputs).extra_headersis no longer necessary. - Support
json_mode="tool"in chat inferences that don't otherwise include tools. - Support
extra_bodyandextra_headerssupplied at inference time without scope filters. - Support
extra_bodyandextra_headerssupplied at inference time withmodel_nameand optionalprovider_namescope filters. - Support thought signatures for the GCP Vertex model providers.
- Support custom tools for the OpenAI model provider.
- Add
descriptionfields to evaluation and evaluator configuration.
