This page tracks Claude model availability on the Anthropic API. This does not include the Claude app, Claude Code, or third-party integrations such as Amazon Bedrock and Google Cloud Vertex AI.

Lifecycle states

  • Active: The model is fully supported and recommended for use.
  • Legacy: The model will no longer receive updates and may be deprecated in the future.
  • Deprecated: The model is no longer available for new customers but continues to be available for existing users until retirement. Anthropic assigns a retirement date at this point.
  • Retired: The model is no longer available for use. Requests to retired models will fail.

Note Deprecated models are likely to be less reliable than active models. Anthropic recommends moving workloads to active models to maintain the highest level of support and reliability.

Customers with active deployments receive at least 60 days’ notice before retirement for publicly released models. Anthropic recommends auditing API usage to discover model usage and testing replacement models before retirement.

Anthropic has committed to preserve the weights of publicly released models and may make past models available again in the future.

Retirement is treated as EOL and Deprecation as End-of-Active-support in the above table and endoflife.date API.

More information is available on the Anthropic Claude website.
