Expand description

The Options struct holds configuration options for the OpenAI client. It includes optional fields for specifying the embedding and prompt models.

Fields§

§embed_model: Option<String>

The default embedding model to use, if specified.

§prompt_model: Option<String>

The default prompt model to use, if specified.

§parallel_tool_calls: Option<bool>

Option to enable or disable parallel tool calls for completions.

At this moment, o1 and o3-mini do not support it and should be set to None.

§max_completion_tokens: Option<u32>

Maximum number of tokens to generate in the completion.

By default, the limit is disabled

§temperature: Option<f32>

Temperature setting for the model.

§reasoning_effort: Option<ReasoningEffort>

Reasoning effor for reasoning models.

§reasoning_features: Option<bool>

Enable reasoning summary/encrypted content handling for the Responses API.

This is enabled by default, but only takes effect when reasoning_effort is set. Disable it with reasoning_features(false) if you do not want summaries or encrypted reasoning stored and replayed.

Note: reasoning summaries/encrypted content require an OpenAI organization that is verified for reasoning access; unverified orgs may receive no summaries.

§seed: Option<i64>

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.

§presence_penalty: Option<f32>

Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model’s likelihood to talk about new topics.

§metadata: Option<Value>

Developer-defined tags and values used for filtering completions in the dashboard.

§user: Option<String>

A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse.

§dimensions: Option<u32>

The number of dimensions the resulting output embeddings should have. Only supported in text-embedding-3 and later models.
