Use openai/gpt-audio-mini with the OpenRouter API:
OpenRouter provides an OpenAI-compatible completion API to 400+ models & providers that you can call directly, or using the OpenAI SDK. Additionally, some third-party SDKs are available.
In the examples below, the OpenRouter-specific headers are optional. Setting them allows your app to appear on the OpenRouter leaderboards.
For information about using third-party SDKs and frameworks with OpenRouter, please see our frameworks documentation.
Add "stream": true to your request body to receive responses as server-sent events:

|---|---|---|---|
seed | integer | — | If specified, the inferencing will sample deterministically, such that repeated requests with the same seed and parameters should return the same result. |
max_tokens | integer | — | This sets the upper limit for the number of tokens the model can generate in response. |
response_format | map | — | Forces the model to produce specific output format. |
temperature | float | 1 | This setting influences the variety in the model's responses. |
top_p | float | 1 | This setting limits the model's choices to a percentage of likely tokens: only the top tokens whose probabilities add up to P. |
stop | array | — | Stop generation immediately if the model encounter any token specified in the stop array. |
frequency_penalty | float | 0 | This setting aims to control the repetition of tokens based on how often they appear in the input. |
presence_penalty | float | 0 | Adjusts how often the model repeats specific tokens already used in the input. |
logit_bias | map | — | Accepts a JSON object that maps tokens (specified by their token ID in the tokenizer) to an associated bias value from -100 to 100. |
logprobs | boolean | — | Whether to return log probabilities of the output tokens or not. |
top_logprobs | integer | — | An integer between 0 and 20 specifying the number of most likely tokens to return at each token position, each with an associated log probability. |
tool_choice | string or object | — | Controls which (if any) tool is called by the model. |
tools | array | — | Tool calling parameter, following OpenAI's tool calling request shape. |
