ParametersExpand Collapse

AssistantListParams params

Optional<String> after

A cursor for use in pagination. after is an object ID that defines your place in the list. For instance, if you make a list request and receive 100 objects, ending with obj_foo, your subsequent call can include after=obj_foo in order to fetch the next page of the list.

Optional<String> before

A cursor for use in pagination. before is an object ID that defines your place in the list. For instance, if you make a list request and receive 100 objects, starting with obj_foo, your subsequent call can include before=obj_foo in order to fetch the previous page of the list.

Optional<Long> limit

A limit on the number of objects to be returned. Limit can range between 1 and 100, and the default is 20.

Optional<Order> order

Sort order by the created_at timestamp of the objects. asc for ascending order and desc for descending order.

ASC("asc")

DESC("desc")

class Assistant:

Represents an assistant that can call the model and use tools.

String id

The identifier, which can be referenced in API endpoints.

long createdAt

The Unix timestamp (in seconds) for when the assistant was created.

Optional<String> description

The description of the assistant. The maximum length is 512 characters.

maxLength512

Optional<String> instructions

The system instructions that the assistant uses. The maximum length is 256,000 characters.

maxLength256000

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.

String model

ID of the model to use. You can use the List models API to see all of your available models, or see our Model overview for descriptions of them.

Optional<String> name

The name of the assistant. The maximum length is 256 characters.

maxLength256

JsonValue; object_

The object type, which is always assistant.

List<AssistantTool> tools

A list of tool enabled on the assistant. There can be a maximum of 128 tools per assistant. Tools can be of types code_interpreter, file_search, or function.

Accepts one of the following:

class CodeInterpreterTool:

JsonValue; type

The type of tool being defined: code_interpreter

class FileSearchTool:

JsonValue; type

The type of tool being defined: 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 for more information.

minimum1

maximum50

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 for more information.

double scoreThreshold

The score threshold for the file search. All values must be a floating point number between 0 and 1.

minimum0

maximum1

Optional<Ranker> ranker

The ranker to use for the file search. If not specified will use the auto ranker.

Accepts one of the following:

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 for examples, and the JSON Schema reference 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.

JsonValue; type

The type of tool being defined: function

Optional<AssistantResponseFormatOption> responseFormat

Specifies the format that the model must output. Compatible with GPT-4o, GPT-4 Turbo, 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.

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.

Accepts one of the following:

JsonValue;

class ResponseFormatText:

Default response format. Used to generate text responses.

JsonValue; type

The type of response format being defined. Always text.

class ResponseFormatJsonObject:

JSON object response format. An older method of generating JSON responses. Using json_schema is recommended for models that support it. Note that the model will not generate JSON without a system or user message instructing it to do so.

JsonValue; type

The type of response format being defined. Always json_object.

class ResponseFormatJsonSchema:

JSON Schema response format. Used to generate structured JSON responses. Learn more about Structured Outputs.

JsonSchema jsonSchema

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 underscores and dashes, with a maximum length of 64.

Optional<String> description

A description of what the response format is for, used by the model to determine how to respond in the format.

Optional<Schema> schema

The schema for the response format, described as a JSON Schema object. Learn how to build JSON schemas here.

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.

JsonValue; type

The type of response format being defined. Always 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.

minimum0

maximum2

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 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 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.
