post

Generates a model response for the given chat conversation.

Authorizations

BearerAuth

AuthorizationstringRequired

Bearer token authentication. Use format "Bearer your-api-key"

Body

application/json

modelstringRequired

ID of the model to use.

Example: dmind/dmind-1

streamboolean | nullableOptional

If set, partial message deltas will be sent.

Default: false

max_tokensinteger | nullableOptional

The maximum number of tokens to generate in the chat completion.

Example: 16384

temperaturenumber | nullableOptional

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.

Default: 1Example: 0.6

top_pnumber | nullableOptional

An alternative to sampling with temperature, called nucleus sampling. So 0.1 means only the tokens comprising the top 10% probability mass are considered.

Default: 1Example: 0.95

top_kinteger | nullableOptional

Limits the number of tokens to consider for each step. Use -1 for no limit.

Default: -1Example: -1

min_pnumber | nullableOptional

Minimum probability threshold for token sampling. Tokens with probability below this threshold are filtered out.

Default: 0Example: 0.1

frequency_penaltynumber | nullableOptional

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.

Default: 0Example: 0

presence_penaltynumber | nullableOptional

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.

Default: 0Example: 0

stopone of | nullableOptional

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

stringOptional

or

string[]Optional

tool_choiceone of | nullableOptional

Controls which (if any) tool is called by the model.

string · enumOptionalPossible values:

or

logprobsboolean | nullableOptional

Whether to return log probabilities of the output tokens.

Default: false

top_logprobsinteger | nullableOptional

How many log probabilities to return per token.
