The 302 platform has added tool invocation capabilities (commonly known as Function Call) to all models. The principle is that if the model itself does not support tool invocation, you only need to pass in the tools parameter. The 302 backend will automatically parse the parameters, convert them into prompts for the model, and transform the model output into the tool_call format.Price: No change in the cost of existing models
Request
Header Params
Content-Type
string
required

application/json
Accept
string
required
Example:
application/json
Authorization
string
required
Fill in the API KEY generated in the management backend - API KEYS after Bearer, for example, Bearer sk-xxxx.
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. We generally recommend altering this or top_p but not both.
top_p
integer
optional
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.
n
integer
optional
How many chat completion choices to generate for each input message.
stream
boolean
optional
If set, partial messages will be sent as they become available, similar to ChatGPT. Tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a [DONE] message. See the OpenAI Cookbook for example code.
stop
string
optional
Up to 4 sequences where the API will stop generating further tokens.
max_tokens
integer
optional
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.
A number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim. See more information about frequency and presence penalties.
logit_bias
null
optional
Modify the likelihood of specified tokens appearing in the completion. Accepts a json object that maps tokens (specified by their 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 prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token.
user
string
optional
A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. Learn more.。
