# Deprecations

> A list of all deprecations, with the most recent announcements appearing first.

<Update label="2026-04-22">
  **Deprecating `llama3.1-8b` and `qwen-3-235b-a22b-instruct-2507`**

  Both models will be fully deprecated on **May 27, 2026**.
</Update>

<Update label="2026-03-24">
  **Deprecating `disable_reasoning` parameter for `zai-glm-4.7`**

  The `disable_reasoning` parameter will no longer be supported after **July 21, 2026**. Migrate to `reasoning_effort="none"` to disable reasoning on `zai-glm-4.7`.

  See the [Reasoning guide](/capabilities/reasoning) and [Chat Completions API reference](/api-reference/chat-completions) for details.
</Update>

<Update label="2026-02-16">
  **Deprecated `qwen-3-32b` and `llama-3.3-70b`**

  We recommend migrating to [GPT OSS 120B](/models/openai-oss).

  <Note>
    **Migration Notes**:

    * Qwen 3 32B had reasoning enabled by default. GPT OSS supports configurable reasoning via the `reasoning_effort` parameter. Review the [Reasoning](/capabilities/reasoning) documentation before migrating.
    * Legacy strict mode (constrained decoding) behavior on `llama-3.3-70b` differs slightly from current Production and Preview models. Review the [Structured Outputs](/capabilities/structured-outputs) and [Tool Use](/capabilities/tool-use) documentation before migrating requests using `tools` and/or `response_format` in strict mode.
  </Note>
