How to read these notices

Selected models on the OpenAI, Claude and Gemini direct APIs. This registry is not exhaustive and does not cover Azure, Amazon Bedrock or Vertex AI.

Sources checked . Updates scheduled Sundays at 09:00 Los Angeles time.

Deprecation announces a change; shutdown ends access to the listed model. Lifecycle labels reflect the provider notice when we verified it. A past planned date alone does not confirm that a model has retired.

“Not before” gives the earliest published date. “During” gives a month, without a confirmed day. An unannounced date is unknown and does not guarantee continued availability. Dates without a stated timezone do not specify an exact cutoff time.

Aliases and dated model snapshots can follow different schedules. Azure, Amazon Bedrock and Vertex AI deployments may differ from these direct API notices. Check the provider, platform and exact model ID.

Provider suggestions are recorded from the linked notice. Evaluate their behavior, API compatibility and operating conditions on your own workflow before switching.

Evaluate the change on your workflow.

Compare the replacement with your current configuration using cases from your product, agreed outcome criteria and documented differences.
