Authorizations

​
Authorization
string
header
required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

application/json
​
model
enum<string>
required

Model ID for the balanced GPT-5.6 Terra tier.

Available options:
gpt-5.6-terra
Example:

"gpt-5.6-terra"

​
input
object[]
required

Text or image input for the model to generate a response.

Minimum array length: 1
Example:
[{ "role": "user", "content": "Hello!" }]
​
stream
boolean
default:false

​
temperature
number
default:1

Sampling temperature. Higher values make output more random.

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

1

​
frequency_penalty
number
default:0

Penalizes repeated tokens based on their frequency in the text so far.

Required range: -2 <= x <= 2
​
presence_penalty
number
default:0

Penalizes tokens that have already appeared in the text.

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

The maximum number of output tokens to generate.

Required range: x >= 16
​
stop
string

Sequences where the model will stop generating further tokens.

​
n
integer
default:1

How many response choices to generate.

Required range: x >= 1
​
text
object

Configuration options for model text response.

​
reasoning
object

Configuration for model reasoning / thinking.

​
tools
object[]

A list of tools the model may call.

​
prompt_cache_options
object

Options for explicit prompt caching when supported.

​
tool_choice
string

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

​
store
boolean
default:true

Whether to store the generated model response for later retrieval via API.

​
safety_identifier
