​
messages
object[]
required

Message list for the conversation. Supports multi-turn by including history.

Required array length: 1 - 50 elements
Example:
[
  {
    "role": "user",
    "content": "What is artificial intelligence?"
  }
]
​
max_tokens
integer
default:1024

Maximum number of tokens to generate. Default 1024. The upper limit depends on the model (use the model list endpoint to check).

Required range: x >= 1
Example:

1024

​
temperature
number
default:1

Controls randomness of the output. Higher values produce more diverse results.

Required range: 0 <= x <= 2
Example:

1

​
top_p
number
default:1

Nucleus sampling parameter. Limits cumulative probability of candidate tokens.

Required range: 0 <= x <= 1
Example:

1

​
presence_penalty
number

Penalizes new topics to reduce repetition

Required range: -2 <= x <= 2
​
frequency_penalty
number

Penalizes frequent tokens to reduce repetition

Required range: -2 <= x <= 2
​
seed
integer

Random seed. Same seed with same input produces deterministic results.

​
n
integer
default:1

Number of responses to generate

Required range: x >= 1
Example:

1

​
stream
boolean
default:false

Whether to stream the response (not supported yet)

Response

Chat completed successfully

OpenAI-compatible Chat Completion response

​
id
string

Unique identifier for the chat completion

Example:

"chatcmpl-abc123def456"

​
object
enum<string>

Object type, always "chat.completion"

Available options:
chat.completion
Example:

"chat.completion"

​
created
integer<int64>

Unix timestamp (in seconds) of when the completion was created

Example:

1711929600

​
model
string

The model used for this completion

Example:

"GEMINI_25_FLASH"

​
choices
object[]

List of completion choices
