+
+        - `Optional<String> description`
+
+          A description of what the function does, used by the model to choose when and how to call the function.
+
+        - `Optional<FunctionParameters> parameters`
+

+
+          Omitting `parameters` defines a function with an empty parameter list.
+
+        - `Optional<Boolean> strict`
+
+          Whether to enable strict schema adherence when generating the function call. If set to true, the model will follow the exact schema defined in the `parameters` field. Only a subset of JSON Schema is supported when `strict` is `true`. Learn more about Structured Outputs in the [function calling guide](https://platform.openai.com/docs/guides/function-calling).
+
+      - `JsonValue; type "function"constant`

+
+    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 JSON mode, which ensures the message the model generates is valid JSON.
+
+    **Important:** when using JSON mode, you **must** also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length.
+
+    - `JsonValue;`
+
+      - `AUTO("auto")`

+      to do so.
+
+      - `JsonValue; type "json_object"constant`
+
+        The type of response format being defined. Always `json_object`.
+
+        - `JSON_OBJECT("json_object")`

+
+        - `Optional<Boolean> strict`
+
+          Whether to enable strict schema adherence when generating the output.
+          If set to true, the model will always follow the exact schema defined
+          in the `schema` field. Only a subset of JSON Schema is supported when
+          `strict` is `true`. To learn more, read the [Structured Outputs
+          guide](https://platform.openai.com/docs/guides/structured-outputs).
+
+      - `JsonValue; type "json_schema"constant`
+
+        The type of response format being defined. Always `json_schema`.
+
+        - `JSON_SCHEMA("json_schema")`
+
+  - `Optional<Double> temperature`
+
+    What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.

+
+      - `Optional<List<String>> fileIds`
+
+        A list of [file](https://platform.openai.com/docs/api-reference/files) IDs made available to the `code_interpreter`` tool. There can be a maximum of 20 files associated with the tool.
+
+    - `Optional<FileSearch> fileSearch`

+      - `Optional<List<String>> vectorStoreIds`
+
+        The ID of the [vector store](https://platform.openai.com/docs/api-reference/vector-stores/object) attached to this assistant. There can be a maximum of 1 vector store attached to the assistant.
+
+  - `Optional<Double> topP`
+
+    An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.
+
+    We generally recommend altering this or temperature but not both.

+
+        Structured Outputs configuration options, including a JSON Schema.
+
+        - `String name`
+
+          The name of the response format. Must be a-z, A-Z, 0-9, or contain

+
+        - `Optional<Schema> schema`
+
+          The schema for the response format, described as a JSON Schema object.
+          Learn how to build JSON schemas [here](https://json-schema.org/).
+
+        - `Optional<Boolean> strict`
+
+          Whether to enable strict schema adherence when generating the output.
+          If set to true, the model will always follow the exact schema defined
+          in the `schema` field. Only a subset of JSON Schema is supported when
+          `strict` is `true`. To learn more, read the [Structured Outputs
+          guide](https://platform.openai.com/docs/guides/structured-outputs).
+
+      - `JsonValue; type "json_schema"constant`

+        - `JSON_SCHEMA("json_schema")`
+
+  - `Optional<Double> temperature`
+
+    What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.
+
+  - `Optional<ToolResources> toolResources`
+
+    A set of resources that are used by the assistant's tools. The resources are specific to the type of tool. For example, the `code_interpreter` tool requires a list of file IDs, while the `file_search` tool requires a list of vector store IDs.
+
+    - `Optional<CodeInterpreter> codeInterpreter`
+
+      - `Optional<List<String>> fileIds`
+
+        A list of [file](https://platform.openai.com/docs/api-reference/files) IDs made available to the `code_interpreter`` tool. There can be a maximum of 20 files associated with the tool.
+
+    - `Optional<FileSearch> fileSearch`
+
+      - `Optional<List<String>> vectorStoreIds`
+
+        The ID of the [vector store](https://platform.openai.com/docs/api-reference/vector-stores/object) attached to this assistant. There can be a maximum of 1 vector store attached to the assistant.
+
+  - `Optional<Double> topP`
+
+    An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.
+
+    We generally recommend altering this or temperature but not both.

+    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`.

+
+    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 JSON mode, which ensures the message the model generates is valid JSON.
+
+    **Important:** when using JSON mode, you **must** also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length.
+

+
+        - `Optional<String> description`
+
+          A description of what the function does, used by the model to choose when and how to call the function.
+
+        - `Optional<FunctionParameters> parameters`
+
+          The parameters the functions accepts, described as a JSON Schema object. See the [guide](https://platform.openai.com/docs/guides/function-calling) for examples, and the [JSON Schema reference](https://json-schema.org/understanding-json-schema/) for documentation about the format.
+
+          Omitting `parameters` defines a function with an empty parameter list.
+
+        - `Optional<Boolean> strict`
+
+          Whether to enable strict schema adherence when generating the function call. If set to true, the model will follow the exact schema defined in the `parameters` field. Only a subset of JSON Schema is supported when `strict` is `true`. Learn more about Structured Outputs in the [function calling guide](https://platform.openai.com/docs/guides/function-calling).
+
+      - `JsonValue; type "function"constant`
+
+        The type of tool being defined: `function`
+
+        - `FUNCTION("function")`
+
+  - `Optional<AssistantResponseFormatOption> responseFormat`
+
+    Specifies the format that the model must output. Compatible with [GPT-4o](https://platform.openai.com/docs/models#gpt-4o), [GPT-4 Turbo](https://platform.openai.com/docs/models#gpt-4-turbo-and-gpt-4), and all GPT-3.5 Turbo models since `gpt-3.5-turbo-1106`.
+
+    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 JSON mode, which ensures the message the model generates is valid JSON.
+
+    **Important:** when using JSON mode, you **must** also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length.

+
+        - `JSON_SCHEMA("json_schema")`
+
+  - `Optional<Double> temperature`

+
+  - `Optional<Double> topP`
+
+    An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.

+
+  ```
+  event: thread.created
+  data: {"id": "thread_123", "object": "thread", ...}
+  ```
+
+  We emit events whenever a new object is created, transitions to a new state, or is being
+  streamed in parts (deltas). For example, we emit `thread.run.created` when a new run
+  is created, `thread.run.completed` when a run completes, and so on. When an Assistant chooses
+  to create a message during a run, we emit a `thread.message.created event`, a
+  `thread.message.in_progress` event, many `thread.message.delta` events, and finally a
+  `thread.message.completed` event.
+
+  We may add additional events over time, so we recommend handling unknown events gracefully
+  in your code. See the [Assistants API quickstart](https://platform.openai.com/docs/assistants/overview) to learn how to
+  integrate the Assistants API with streaming.

+
+        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 JSON mode, which ensures the message the model generates is valid JSON.
+
+        **Important:** when using JSON mode, you **must** also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length.

+
+        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 JSON mode, which ensures the message the model generates is valid JSON.
+
+        **Important:** when using JSON mode, you **must** also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length.

+              If set to true, the model will always follow the exact schema defined
+              in the `schema` field. Only a subset of JSON Schema is supported when

+
+### Parameters
+
+- `ThreadCreateAndRunParams params`
+
+  - `String assistantId`
+
+    The ID of the [assistant](https://platform.openai.com/docs/api-reference/assistants) to use to execute this run.
+
+  - `Optional<String> instructions`
+
+    Override the default system message of the assistant. This is useful for modifying the behavior on a per-run basis.
+
+  - `Optional<Long> maxCompletionTokens`
+
+    The maximum number of completion tokens that may be used over the course of the run. The run will make a best effort to use only the number of completion tokens specified, across multiple turns of the run. If the run exceeds the number of completion tokens specified, the run will end with status `incomplete`. See `incomplete_details` for more info.
+
+  - `Optional<Long> maxPromptTokens`
+
+    The maximum number of prompt tokens that may be used over the course of the run. The run will make a best effort to use only the number of prompt tokens specified, across multiple turns of the run. If the run exceeds the number of prompt tokens specified, the run will end with status `incomplete`. See `incomplete_details` for more info.
+
+  - `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
+    format, and querying for objects via API or the dashboard.
+
+    Keys are strings with a maximum length of 64 characters. Values are strings
+    with a maximum length of 512 characters.
+
+  - `Optional<ChatModel> model`
+
+    The ID of the [Model](https://platform.openai.com/docs/api-reference/models) to be used to execute this run. If a value is provided here, it will override the model associated with the assistant. If not, the model associated with the assistant will be used.
+
+  - `Optional<Boolean> parallelToolCalls`
+
+    Whether to enable [parallel function calling](https://platform.openai.com/docs/guides/function-calling#configuring-parallel-function-calling) during tool use.
+
+  - `Optional<AssistantResponseFormatOption> responseFormat`
+
+    Specifies the format that the model must output. Compatible with [GPT-4o](https://platform.openai.com/docs/models#gpt-4o), [GPT-4 Turbo](https://platform.openai.com/docs/models#gpt-4-turbo-and-gpt-4), and all GPT-3.5 Turbo models since `gpt-3.5-turbo-1106`.
+
+    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 JSON mode, which ensures the message the model generates is valid JSON.
+
+    **Important:** when using JSON mode, you **must** also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length.
+
+  - `Optional<Double> temperature`
+
+    What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.

+    Specifies the format that the model must output. Compatible with [GPT-4o](https://platform.openai.com/docs/models#gpt-4o), [GPT-4 Turbo](https://platform.openai.com/docs/models#gpt-4-turbo-and-gpt-4), and all GPT-3.5 Turbo models since `gpt-3.5-turbo-1106`.
+
+    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 JSON mode, which ensures the message the model generates is valid JSON.
+
+    **Important:** when using JSON mode, you **must** also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length.

+### Assistant Response Format Option
+
+- `class AssistantResponseFormatOption: A class that can be one of several variants.union`
+
+  Specifies the format that the model must output. Compatible with [GPT-4o](https://platform.openai.com/docs/models#gpt-4o), [GPT-4 Turbo](https://platform.openai.com/docs/models#gpt-4-turbo-and-gpt-4), and all GPT-3.5 Turbo models since `gpt-3.5-turbo-1106`.
+
+  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).

+
+    - `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
+      format, and querying for objects via API or the dashboard.

+
+    The maximum number of completion tokens that may be used over the course of the run. The run will make a best effort to use only the number of completion tokens specified, across multiple turns of the run. If the run exceeds the number of completion tokens specified, the run will end with status `incomplete`. See `incomplete_details` for more info.
+
+  - `Optional<Long> maxPromptTokens`
+
+    The maximum number of prompt tokens that may be used over the course of the run. The run will make a best effort to use only the number of prompt tokens specified, across multiple turns of the run. If the run exceeds the number of prompt tokens specified, the run will end with status `incomplete`. See `incomplete_details` for more info.
+
+  - `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
+    format, and querying for objects via API or the dashboard.
+
+    Keys are strings with a maximum length of 64 characters. Values are strings
+    with a maximum length of 512 characters.
+
+  - `Optional<ChatModel> model`
+
+    The ID of the [Model](https://platform.openai.com/docs/api-reference/models) to be used to execute this run. If a value is provided here, it will override the model associated with the assistant. If not, the model associated with the assistant will be used.
+
+  - `Optional<Boolean> parallelToolCalls`
+
+    Whether to enable [parallel function calling](https://platform.openai.com/docs/guides/function-calling#configuring-parallel-function-calling) during tool use.
+
+  - `Optional<ReasoningEffort> reasoningEffort`
+
+    Constrains effort on reasoning for
+    [reasoning models](https://platform.openai.com/docs/guides/reasoning).
+    Currently supported values are `none`, `minimal`, `low`, `medium`, `high`, and `xhigh`. Reducing
+    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<AssistantResponseFormatOption> responseFormat`
+
+    Specifies the format that the model must output. Compatible with [GPT-4o](https://platform.openai.com/docs/models#gpt-4o), [GPT-4 Turbo](https://platform.openai.com/docs/models#gpt-4-turbo-and-gpt-4), and all GPT-3.5 Turbo models since `gpt-3.5-turbo-1106`.
+
+    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 JSON mode, which ensures the message the model generates is valid JSON.
+
+    **Important:** when using JSON mode, you **must** also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length.
+
+  - `Optional<Double> temperature`
+
+    What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.
+
+  - `Optional<AssistantToolChoiceOption> toolChoice`
+
+    Controls which (if any) tool is called by the model.
+    `none` means the model will not call any tools and instead generates a message.
+    `auto` is the default value and means the model can pick between generating a message or calling one or more tools.
+    `required` means the model must call one or more tools before responding to the user.
+    Specifying a particular tool like `{"type": "file_search"}` or `{"type": "function", "function": {"name": "my_function"}}` forces the model to call that tool.
+
+  - `Optional<List<AssistantTool>> tools`
+
+    Override the tools the assistant can use for this run. This is useful for modifying the behavior on a per-run basis.
+
+    - `class CodeInterpreterTool:`
+
+    - `class FileSearchTool:`
+
+      - `JsonValue; type "file_search"constant`
+
+        The type of tool being defined: `file_search`
+
+        - `FILE_SEARCH("file_search")`
+
+      - `Optional<FileSearch> fileSearch`
+
+        Overrides for the file search tool.
+
+        - `Optional<Long> maxNumResults`
+
+          The maximum number of results the file search tool should output. The default is 20 for `gpt-4*` models and 5 for `gpt-3.5-turbo`. This number should be between 1 and 50 inclusive.
+
+          Note that the file search tool may output fewer than `max_num_results` results. See the [file search tool documentation](https://platform.openai.com/docs/assistants/tools/file-search#customizing-file-search-settings) for more information.
+
+        - `Optional<RankingOptions> rankingOptions`
+
+          The ranking options for the file search. If not specified, the file search tool will use the `auto` ranker and a score_threshold of 0.
+
+          See the [file search tool documentation](https://platform.openai.com/docs/assistants/tools/file-search#customizing-file-search-settings) for more information.
+
+          - `double scoreThreshold`
+
+            The score threshold for the file search. All values must be a floating point number between 0 and 1.
+
+          - `Optional<Ranker> ranker`
+
+            The ranker to use for the file search. If not specified will use the `auto` ranker.
+
+            - `AUTO("auto")`
+
+            - `DEFAULT_2024_08_21("default_2024_08_21")`
+
+    - `class FunctionTool:`
+
+      - `FunctionDefinition function`
+
+        - `String name`
+
+          The name of the function to be called. Must be a-z, A-Z, 0-9, or contain underscores and dashes, with a maximum length of 64.
+
+        - `Optional<String> description`
+
+          A description of what the function does, used by the model to choose when and how to call the function.
+
+        - `Optional<FunctionParameters> parameters`
+
+          The parameters the functions accepts, described as a JSON Schema object. See the [guide](https://platform.openai.com/docs/guides/function-calling) for examples, and the [JSON Schema reference](https://json-schema.org/understanding-json-schema/) for documentation about the format.
+
+          Omitting `parameters` defines a function with an empty parameter list.
+
+        - `Optional<Boolean> strict`
+
+          Whether to enable strict schema adherence when generating the function call. If set to true, the model will follow the exact schema defined in the `parameters` field. Only a subset of JSON Schema is supported when `strict` is `true`. Learn more about Structured Outputs in the [function calling guide](https://platform.openai.com/docs/guides/function-calling).
+
+      - `JsonValue; type "function"constant`
+
+        The type of tool being defined: `function`
+
+        - `FUNCTION("function")`
+
+  - `Optional<Double> topP`
+
+    An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.
+
+    We generally recommend altering this or temperature but not both.
+
+  - `Optional<TruncationStrategy> truncationStrategy`
+
+    Controls for how a thread will be truncated prior to the run. Use this to control the initial context window of the run.
+
+    - `Type type`
+
+      The truncation strategy to use for the thread. The default is `auto`. If set to `last_messages`, the thread will be truncated to the n most recent messages in the thread. When set to `auto`, messages in the middle of the thread will be dropped to fit the context length of the model, `max_prompt_tokens`.
+
+      - `AUTO("auto")`
+
+      - `LAST_MESSAGES("last_messages")`
+
+    - `Optional<Long> lastMessages`
+
+      The number of most recent messages from the thread when constructing the context for the run.

+
+    Setting to `{ "type": "json_object" }` enables JSON mode, which ensures the message the model generates is valid JSON.
+
+    **Important:** when using JSON mode, you **must** also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length.

+
+    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 JSON mode, which ensures the message the model generates is valid JSON.
+
+    **Important:** when using JSON mode, you **must** also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length.

+
+          The type of tool call the output is required for. For now, this is always `function`.
+
+          - `FUNCTION("function")`
+
+    - `JsonValue; type "submit_tool_outputs"constant`

+
+    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 JSON mode, which ensures the message the model generates is valid JSON.
+
+    **Important:** when using JSON mode, you **must** also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length.
