[!WARNING] Completed Deprecations

  • Removed the deprecated model_provider_name filter for extra_body and extra_headers. Please use model_name and provider_name instead.
  • Removed the legacy experimental list_inferences endpoint and method. Please use the new endpoint instead. [docs]
  • Removed several long-deprecated types and methods from the TensorZero Python SDK.

[!WARNING] Planned Deprecations

  • The embedded gateway in the TensorZero Python SDK will be removed in a future release (2026.6+). patch_openai_client and build_embedded are deprecated. Please deploy a standalone TensorZero Gateway instead (usage: base_url for OpenAI SDK; build_http for TensorZero SDK).
  • The variant configuration field weight will be removed in a future release (2026.6+). Please use the new experimentation configuration semantics. [docs]

Bug Fixes

  • Fixed a compatibility bug with Valkey-based caching that only affected Redis.

New Features

  • Added support for launching optimization workflows with dataset_name (instead of an inference query) in launch_optimization_workflow.

& multiple under-the-hood and UI improvements!
