The ID of the model to use. For details on which models are compatible with the chat API, see the model endpoint compatibility table.

Messages in chat format used to generate chat completions.

Sampling temperature to use, between 0 and 2. Higher values (such as 0.8) make the output more random, while lower values (such as 0.2) make it more focused and deterministic. We generally recommend adjusting this or top_p but not both.

An alternative to temperature sampling, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only tokens that make up the top 10% probability mass are considered. We generally recommend adjusting this or temperature but not both.

How many chat completion choices to generate for each input message.

If set, partial message deltas will be sent, similar to ChatGPT. Tokens will be sent as plain data [server-sent events](: [DONE]`, and the stream is terminated by the message. For example code, please refer to the OpenAI Cookbook.

Up to 4 sequences where the API will stop generating further tokens.

The maximum number of tokens to generate in the chat completion. The total length of input tokens and generated tokens is limited by the model’s context length.

Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they have appeared in the text so far, increasing the likelihood that the model talks about new topics. See more about frequency and presence penalties.

Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text, reducing the likelihood that the model repeats the same line verbatim. See more about frequency and presence penalties.

Modify the likelihood of specified tokens appearing in the completion. Accepts a JSON object that maps tokens (specified by 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 before sampling. The exact effect varies by model, but values between -1 and 1 should decrease or increase the likelihood of selection; values like -100 or 100 should result in the relevant tokens being effectively banned or selected exclusively.

Positive prompt words for generating content (required).

The aspect ratio of the generated media (optional).

The format of the output image (optional).

Enable synchronous mode (optional). If set to true, the function will wait for the result to be generated and uploaded before returning the response. It allows directly obtaining the result in the response, and is only available through the API.

Enable BASE64 output (optional). If enabled, the output will be encoded as a BASE64 string instead of a URL, and is only available via the API.

Callback interface address (optional). After the generation task is completed, the system will send a result request to this link. A return status code of 200 indicates successful reception.
