    DeepSeek V4 Pro (0813) Model Serving Foundation Model APIs

    DeepSeek V4 Pro (0813) is retired from Foundation Model APIs on 30 October 2026. Databricks names DeepSeek V4.1 Flash as the replacement.

    Move workloads to DeepSeek V4.1 Flash, and follow the deprecated and retired models guidance for anything pinned to the 0813 version.

Here because older tutorials still recommend them, and because an incident on one of these starts with an upgrade.

    Llama 3.1 405B Model Serving

    Retired from pay-per-token in February 2026 and from provisioned throughput in May.

    GPT-5.1 Codex Max, Codex Mini and GPT-5.2 Codex Model Serving

    Gemini 2.5 Flash and 2.5 Pro Model Serving

    Both retire on the same day, Flash from pay-per-token and Pro from provisioned throughput.

    Databricks points at Gemini 3.1 Pro or 3.5 Flash. Budget time for re-evaluating, not just renaming the endpoint.

    Claude Sonnet 4 on Foundation Model APIs Model Serving

    Retired from pay-per-token serving. Requests to it will stop working.

    Move to Claude Sonnet 4.6 and re-run your evaluations: a newer model is not a drop-in for prompt behaviour.

Dates come from the Databricks documentation and are re-checked by the agent. A runtime version is supported for roughly six months, and a long-term support version for three years from its general availability. Model retirements get at least three months of notice after the deprecation is announced.

End-of-support dates are announced months ahead and then forgotten. Tick “Deprecations and end of support” and the ones that touch what you use arrive in your inbox while there is still time to move.
