-**Starting a new project?** We recommend trying [Responses](https://platform.openai.com/docs/api-reference/responses)
-to take advantage of the latest OpenAI platform features. Compare
-[Chat Completions with Responses](https://platform.openai.com/docs/guides/responses-vs-chat-completions?api-mode=responses).

-
-Creates a model response for the given chat conversation. Learn more in the
-[text generation](https://platform.openai.com/docs/guides/text-generation), [vision](https://platform.openai.com/docs/guides/vision),
-and [audio](https://platform.openai.com/docs/guides/audio) guides.
-
-Parameter support can differ depending on the model used to generate the
-response, particularly for newer reasoning models. Parameters that are only
-supported for reasoning models are noted below. For the current state of
-unsupported parameters in reasoning models,
-[refer to the reasoning guide](https://platform.openai.com/docs/guides/reasoning).
-
-Returns a chat completion object, or a streamed sequence of chat completion
-chunk objects if the request is streamed.
-
-### Parameters

-
-    `none` is the default when no functions are present. `auto` is the default
-    if functions are present.

-    Modify the likelihood of specified tokens appearing in the completion.
-
-    Accepts a JSON object that maps tokens (specified by their token ID in the
-    tokenizer) to an associated bias value from -100 to 100. Mathematically,
-    the bias is added to the logits generated by the model prior to sampling.
-    The exact effect will vary per model, but values between -1 and 1 should

-    should result in a ban or exclusive selection of the relevant token.
-

-
-    The maximum number of [tokens](/tokenizer) that can be generated in the
-    chat completion. This value can be used to control
-    [costs](https://openai.com/api/pricing/) for text generated via API.
-
-    This value is now deprecated in favor of `max_completion_tokens`, and is
-    not compatible with [o-series models](https://platform.openai.com/docs/guides/reasoning).
-
-  - `Optional<Metadata> metadata`
-
-    Set of 16 key-value pairs that can be attached to an object. This can be
-    useful for storing additional information about the object in a structured

-
-    Keys are strings with a maximum length of 64 characters. Values are strings
-    with a maximum length of 512 characters.
-
-  - `Optional<List<Modality>> modalities`
-
-    Output types that you would like the model to generate.
-    Most models are capable of generating text, which is the default:
-
-    `["text"]`
-
-    The `gpt-4o-audio-preview` model can also be used to
-    [generate audio](https://platform.openai.com/docs/guides/audio). To request that this model generate
-    both text and audio responses, you can use:
-
-    `["text", "audio"]`
-
-    - `TEXT("text")`
-
-    - `AUDIO("audio")`
-
-  - `Optional<Long> n`

-    being regenerated.
-
-  - `Optional<Double> presencePenalty`

-    whether they appear in the text so far, increasing the model's likelihood
-    to talk about new topics.
-
-  - `Optional<String> promptCacheKey`

-    reasoning effort can result in faster responses and fewer tokens used
-    on reasoning in a response.
-
-    - `gpt-5.1` defaults to `none`, which does not perform reasoning. The supported reasoning values for `gpt-5.1` are `none`, `low`, `medium`, and `high`. Tool calls are supported for all reasoning values in gpt-5.1.
-    - All models before `gpt-5.1` default to `medium` reasoning effort, and do not support `none`.
-    - The `gpt-5-pro` model defaults to (and only supports) `high` reasoning effort.
-    - `xhigh` is supported for all models after `gpt-5.1-codex-max`.
-
-  - `Optional<ResponseFormat> responseFormat`
-
-    An object specifying the format that the model must output.
-
-    Setting to `{ "type": "json_schema", "json_schema": {...} }` enables
-    Structured Outputs which ensures the model will match your supplied JSON
-    schema. Learn more in the [Structured Outputs
-    guide](https://platform.openai.com/docs/guides/structured-outputs).
-
-    Setting to `{ "type": "json_object" }` enables the older JSON mode, which
-    ensures the message the model generates is valid JSON. Using `json_schema`
-    is preferred for models that support it.

[Learn more](https://platform.openai.com/docs/guides/safety-best-practices#safety-identifiers).
-
-  - `Optional<Long> seed`
-
-    This feature is in Beta.
-    If specified, our system will make a best effort to sample deterministically, such that repeated requests with the same `seed` and parameters should return the same result.
-    Determinism is not guaranteed, and you should refer to the `system_fingerprint` response parameter to monitor changes in the backend.
-
-  - `Optional<ServiceTier> serviceTier`
-
-    Specifies the processing type used for serving the request.
-
-    - If set to 'auto', then the request will be processed with the service tier configured in the Project settings. Unless otherwise configured, the Project will use 'default'.

-    - If set to '[flex](https://platform.openai.com/docs/guides/flex-processing)' or '[priority](https://openai.com/api-priority-processing/)', then the request will be processed with the corresponding service tier.
-    - When not set, the default behavior is 'auto'.
-
-    When the `service_tier` parameter is set, the response body will include the `service_tier` value based on the processing mode actually used to serve the request. This response value may be different from the value set in the parameter.

-
-**post** `/chat/completions/{completion_id}`
