Please hold this release while the accidental major bump is corrected. The unsupported model-slug correction should remain on the 4.x line under the documented versioning exception. Regenerate this release as 4.66.0 and verify the version files, changelog, and CI before approval.

| * **api:** correct model types and network policy docs ([f8cce9a](https://github.com/openai/openai-java/commit/f8cce9a5e1376e793aedbaf6f94d2a0789d858bf)) |

For consumers referencing ChatModel.GPT_5_1_MINI or the analogous generated model members, upgrading to 4.66.0 causes compilation failures or NoSuchFieldError because f8cce9a removes those public fields and enum cases, yet this entry presents the change only as a generic bug fix. Add an explicit breaking-changes note naming the removed symbols and directing users to select an available model so affected consumers do not discover the incompatibility only during an upgrade.

| ### ⚠ BREAKING CHANGES | ||
|
|
||
| * **api:** Removed the unsupported `gpt-5.1-mini` model's `GPT_5_1_MINI` constants and corresponding `Known`/`Value` enum cases from `ChatModel` and both beta and stable `ResponseCompactParams.Model` types. Code referencing these members must select an available model and be recompiled. This removal is covered by the SDK's minor-version compatibility exception. |

The newly added breaking-change note still omits public members removed by f8cce9a: BetaResponse.Model.GPT_5_1_MINI, BetaResponsesClientEvent.ResponseCreate.Model.GPT_5_1_MINI, and beta ResponseCreateParams.Model.GPT_5_1_MINI (plus their Known/Value cases). Consumers referencing any of these symbols will get the same compilation failure or NoSuchFieldError, but the note currently claims the removal is limited to ChatModel and the two compact-parameter types; enumerate the remaining affected types so those users receive accurate migration guidance.

The updated changelog now explicitly confirms that this release removes public constants and enum members from stable types such as ChatModel and ResponseCompactParams and requires consumers to recompile, but the build still publishes it as 4.66.0. Consumers accepting compatible 4.x updates can therefore receive a binary-incompatible JAR and fail with NoSuchFieldError (or compilation errors); update all release markers to a new major version instead.

The requested version correction is present at @markstuart-oai, please re-review the corrected release and clear the changes-requested hold if it now meets your requirements. This release includes the merged credential-header correction in #1036. Further separately reviewed Java fixes are being prepared; this request does not claim those have merged or that Maven delivery has completed. |

Re-reviewed the release correction at ef48fb37d7aac152386f0c3f9173ca5eb3781384. The manifest, Gradle project version, README/CONTRIBUTING examples and Bedrock examples consistently specify 4.66.0. The changelog now identifies the removed model constants and enum cases, the recompilation/migration requirement, and the documented minor-version exception. These changes address my earlier version-correction review; no further actionable findings in this release diff.
Current-commit hosted CI passes, including API/Jackson compatibility, tests, build/lint, version support and Java 8/25 runtime checks. Review used pinned source and hosted results; tests were not independently rerun.
The current commit still contains the documented model-member removal. The planned restoration and corresponding changelog refresh remain prerequisites before release; this approval does not establish that regeneration or package publication has completed.
