Anthropic Python SDK v0.109.2 Removes Retired Models
Anthropic released version 0.109.2 of its Python SDK on June 15, 2026, removing retired models from the API and SDK. The release represents a cleanup effort to remove deprecated model endpoints.
What Changed
The update includes a single change: the removal of retired models from both the API and SDK codebase. The specific models removed were not detailed in the release notes.
The release includes no new features, bug fixes, or performance improvements beyond this cleanup task.
Version Details
The release jumps from v0.109.1 to v0.109.2, indicating a patch-level update. The commit hash for this release is ebb1715.
Developers using the Anthropic Python SDK should update to ensure their code references only currently supported models. Applications attempting to access removed model endpoints may encounter errors after updating.
What This Means
This is a routine maintenance release that removes deprecated functionality from Anthropic's Python SDK. The removal of retired models suggests Anthropic is actively managing its model lifecycle and cleaning up legacy endpoints. Developers should review their code for references to older models and migrate to current model versions if necessary. The lack of a migration guide in the release notes indicates these were likely models already announced as deprecated in previous communications.
