Create chat completion

Creates a model response for the given chat conversation. Passing parameters in through the SDK overrides the Portal configuration.

Maitai Specific Parameters

session_id
string
required

A unique identifier you set for the session.

intent
string
required

Specifies the type the intention of the request.

Examples: CONVERSATION

application
string
required

The reference to the application the request is created from.

metadata
map<string, string>

Optional metadata used to reference the request/session later.

reference_id
string

Optional. A reference identifier for identifying the request in your session.

callback
function(EvaluationResponse)

Optional. A callback function that may be used to handle the resulting Maitai evaluation asynchronously.

evaluation_enabled
boolean
default: true

Indicates whether or not to evaluate model output.

apply_corrections
boolean
default: false

Indicates whether or not to apply corrections if a fault is found during evaluation. This is also referred to as “autocorrect”.

safe_mode
boolean
default: false

Safe Mode ensures that corrections all LLM outputs are evaluated and corrected, with no consideration for latency.

assistant
boolean
default: false

Whether to run as an Assistant. See Assistants for more info

user_id
string
default: ""

Optional. Unique identifier for a user, used for long term memory.

context_retrieval_enabled
boolean
default: false

Indicates whether or not to retrieve and inject applicable context parts.

context_query
string
default: ""

Optional. A query used for retrieving applicable context. If not provided while context_retrieval_enabled is true, a query will be inferred.

fallback_model
string
default: ""

Optional. Model to be used if primary model fails or is experiencing an outage.

server_side_inference
boolean
default: false

Indicates whether the inference should be performed server-side. Only OpenAI models can be run client-side.

user_id
string
default: ""

The unique identifier for the end-user. If this is supplied, we’ll create, store, and search core memories to provide inter-session context.

Model Provider Parameters

messages
array
required

A list of messages comprising the conversation so far.

model
string

ID of the model to use. Providing in parameters overwrites portal config.

frequency_penalty
number or null
default: 0

Defaults to 0. 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.

logit_bias
map
default: "null"

Defaults to null. 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.

logprobs
boolean or null
default: false

Whether to return log probabilities of the output tokens or not. If true, returns the log probabilities of each output token returned in the content of message.

top_logprobs
integer or null

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. logprobs must be set to true if this parameter is used.

max_tokens
integer or null

The maximum number of tokens that can be generated in the chat completion.

The total length of input tokens and generated tokens is limited by the model’s context length.

max_completion_tokens
integer or null

The maximum number of tokens that can be generated in the chat completion.

The total length of input tokens and generated tokens is limited by the model’s context length.

n
integer or null
default: 1

How many chat completion choices to generate for each input message. Note that you will be charged based on the number of generated tokens across all of the choices. Keep n as 1 to minimize costs.

presence_penalty
number or null
default: 0

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.

response_format
object

An object specifying the format that the model must output. Compatible with GPT-4 Turbo and all GPT-3.5 Turbo models newer than gpt-3.5-turbo-1106.

Setting to {"type": "json_object"} enables JSON mode, which guarantees the message the model generates is valid JSON.

Important: when using JSON mode, you must also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly “stuck” request. Also note that the message content may be partially cut off if finish_reason="length", which indicates the generation exceeded max_tokens or the conversation exceeded the max context length.

seed
integer or null

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.

stop
string / array / null
default: "null"

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

stream
boolean or null
default: false

If set, partial message deltas will be sent, like in ChatGPT. Tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a data: [DONE] message. Example Python code.

stream_options
object or null
default: {"include_usage":true}

Optional. Defaults to null. Options for streaming response. Only set this when you set stream: true.

temperature
number or null
default: 1

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
number or null
default: 1

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.

tools
array

A list of tools the model may call. Currently, only functions are supported as a tool. Use this to provide a list of functions the model may generate JSON inputs for. A max of 128 functions are supported.

tool_choice
string

none means the model will not call any tool and instead generates a message. auto means the model can pick between generating a message or calling one or more tools. required means the model must call one or more tools.

tool_choice
object

Specifies a tool the model should use. Use to force the model to call a specific function.

user
string

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

function_call
string
deprecated

none means the model will not call a function and instead generates a message. auto means the model can pick between generating a message or calling a function.

function_call
object
deprecated

Specifying a particular function via {"name": "my_function"} forces the model to call that function.

functions
array
deprecated

Deprecated in favor of tools.

A list of functions the model may generate JSON inputs for.
