Anthropic Python SDK v0.106.0 marks Claude Opus 4.1 as deprecated
Anthropic released version 0.106.0 of its Python SDK on June 5, 2026, marking Claude Opus 4.1 as deprecated. The update also includes bug fixes for Foundry client methods and schema transformation handling.
Claude Opus 4.1 Marked Deprecated in Python SDK
Anthropic released version 0.106.0 of its Python SDK on June 5, 2026, with the primary change being the deprecation of Claude Opus 4.1. The SDK update signals the model is no longer recommended for new implementations.
Technical Changes
The release includes two bug fixes:
Foundry Client Fix: The copy() and with_options() methods now function correctly on the Foundry client, resolving issues developers encountered when attempting to clone or modify client configurations.
Schema Transformation: The SDK now properly preserves $defs (schema definitions) when the schema root is a $ref (reference). This fix addresses a data structure handling issue that could affect developers using complex JSON schemas with their API calls.
Documentation Updates
Anthropic updated its security reporting documentation to direct vulnerability reports to the company's HackerOne program, standardizing the security disclosure process.
Internal changes included artifact URL corrections and branch name updates in the repository structure.
What This Means
The deprecation of Claude Opus 4.1 indicates Anthropic is phasing out this model version, likely in favor of newer iterations. Developers using Opus 4.1 in production should plan migration to supported model versions. The model remains accessible in the SDK but will likely be removed in a future release.
The Foundry client fixes are particularly relevant for enterprise users working with Anthropic's Foundry platform, enabling proper client configuration management that was previously broken. The schema transformation fix prevents data loss in complex API interactions, particularly important for applications using structured outputs or tool calling features.
This is a maintenance release focused on deprecation signaling and bug fixes rather than new features.
