| * **api:** correct model types and network policy docs ([618bb31](https://github.com/openai/openai-python/commit/618bb312e52c2b62f75f56602b7388e6d023aa33)) |

For users who passed the literal "gpt-5.1-mini" through typed Chat or Responses APIs, upgrading to 3.17.0 now causes type-checking failures because 618bb31 removes that value from the public ChatModel literals. That source commit explicitly marks the removal as an intentional breaking change, but this release note reduces it to an ordinary “correct model types” fix, so affected users receive no actionable upgrade warning. Add a breaking-changes entry that names the removed model choice.

The final release no longer removes this model literal. PR 3931 restored gpt-5.1-mini; I verified it is present in both public ChatModel aliases and the sync/async Responses model literals at release commit 8c72a700d900fb2578227df564a54462abfe67f8. Therefore a warning that 3.17.0 removes it would now be incorrect. This preserves typing compatibility and does not promise that the model is available.

This release includes 618bb31, whose fix(api)! commit explicitly declares an intentional breaking change and removes "gpt-5.1-mini" from the public ChatModel literals. Versioning it as 3.17.0 allows constraints such as openai>=3,<4 to install the incompatible API automatically, causing affected typed call sites to fail without opting into a major upgrade. Beyond documenting the removal in the changelog, bump the package, manifest, lockfile, and release heading to 4.0.0, or defer the breaking commit.

The breaking type removal was deferred rather than shipped. PR 3931 restored gpt-5.1-mini before the final 3.17.0 release; it is present in the public model aliases and Responses literals at 8c72a700d900fb2578227df564a54462abfe67f8. The final release head reviewed by the owners was 12011e3caf07085d6a1f0bd06127cf1e6deb2e04. A major bump is not needed for this now-absent removal, and I am not changing the published version or release metadata.

@marcuswood-oai @jbeckwith-oai In response to the release disposition, the earlier change request, and the final review: the objection applied to an earlier head; the final owner-approved head is The release workflow reports success. That is publication-workflow evidence, not a package download/install check performed by me. I am not dismissing any review, repeating an administrative merge, or modifying release metadata. |
