It does not require any setup or authentication and is an instant way to preview and test a model directly in the browser.

Required when modalities includes 'audio'. frequency\_penalty `number | null`Penalizes new tokens based on their existing frequency in the text so far. logit\_bias `object | null`Modify the likelihood of specified tokens appearing in the completion. Maps token IDs to bias values from -100 to 100. logprobs `boolean | null`Whether to return log probabilities of the output tokens. top\_logprobs `integer | null`How many top log probabilities to return at each token position (0-20). Requires logprobs=true. max\_tokens `integer | null`The maximum number of tokens to generate. max\_completion\_tokens `integer | null`An upper bound for the number of tokens that can be generated for a completion. metadata `object | null`Set of key-value pairs that can be attached to the object. modalities `array | null`Output types requested from the model. n `integer | null`How many chat completion choices to generate for each input message. parallel\_tool\_calls `boolean`default: trueWhether to enable parallel function calling during tool use. ▶prediction{} `object` presence\_penalty `number | null`Penalizes new tokens based on whether they appear in the text so far. ▶chat\_template\_kwargs{} `object`Chat-template controls. ▶response\_format `one of`Specifies the format the model must output. seed `integer | null`If specified, the system will make a best effort to sample deterministically. ▶stop `one of` store `boolean | null`Whether to store the output for model distillation or evaluation. stream `boolean | null`If true, partial message deltas will be sent as server-sent events. ▶stream\_options{} `object` temperature `number | null`Sampling temperature between 0 and 2. ▶tool\_choice `one of`Controls which (if any) tool is called by the model. 'none' = no tools, 'auto' = model decides, 'required' = must call a tool. ▶tools\[] `array`A list of tools the model may call. top\_p `number | null`Nucleus sampling: considers the results of the tokens with top\_p probability mass. user `string`A unique identifier representing your end-user, for abuse monitoring. ▶web\_search\_options{} `object`Options for the web search tool (when using built-in web search). ▶function\_call `one of` ▶functions\[] `array`minItems: 1maxItems: 128 prompt `string`requiredminLength: 1The input text prompt for the model to generate a response. ### Output
Synchronous — Send a request and receive a complete response id stringA unique identifier for the chat completion. object string created integerUnix timestamp (seconds) of when the completion was created. model stringThe model used for the chat completion. ▶choices\[] arrayminItems: 1 ▶usage{} object system\_fingerprint string | null
Streaming — Send a request with `stream: true` and receive server-sent events type string contentType text/event-stream format binary
