Chat completions

text

POST https://api.continuumlabs.ai/v1/chat/completions

Send a conversation and get the model's next message. This is the same format as OpenAI's chat completions endpoint.

Request

bash

curl https://api.continuumlabs.ai/v1/chat/completions \
  -H "Authorization: Bearer cl-your-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "glm-5.2",
    "messages": [
      {"role": "system", "content": "You are a careful assistant. Use Australian English."},
      {"role": "user", "content": "Summarise the Notifiable Data Breaches scheme in two sentences."}
    ],
    "temperature": 0.2,
    "max_tokens": 300
  }'

Parameters

Parameter	Type	What it does
`model`	string, required	Which model to use. See models.
`messages`	array, required	The conversation so far. Each message has a `role` (`system`, `user`, `assistant` or `tool`) and `content`.
`temperature`	number	Randomness, from 0 to 2. Use 0 to 0.3 for extraction and analysis, higher for drafting.
`max_tokens`	integer	The most tokens the model may write in its reply. Defaults to 4,096, up to 32,768. Also sets the most a request can cost, which is set aside from your credit until it finishes.
`top_p`	number	An alternative to temperature. Change one or the other, not both.
`stop`	string or array	Text that ends the reply when the model writes it.
`stream`	boolean	Send the reply as it is written. See streaming.
`tools`	array	Functions the model may call. See tool calling.
`tool_choice`	string or object	`auto`, `none`, `required`, or a specific function.
`response_format`	object	`{"type": "json_object"}` for JSON. See JSON output.

Other OpenAI parameters are passed to the model unchanged. Whether a model honours them depends on the model.

Response

json

{
  "id": "chatcmpl-...",
  "object": "chat.completion",
  "model": "glm-5.2",
  "choices": [
    {
      "index": 0,
      "message": {"role": "assistant", "content": "The scheme requires..."},
      "finish_reason": "stop"
    }
  ],
  "usage": {"prompt_tokens": 41, "completion_tokens": 58, "total_tokens": 99}
}

Field	What it means
`choices[0].message.content`	The model's reply.
`choices[0].message.tool_calls`	Functions the model wants to call, if you sent `tools`.
`choices[0].finish_reason`	`stop` when the model finished, `length` when it hit `max_tokens`, `tool_calls` when it wants to call a function.
`usage`	Tokens used. This is what your account is charged for.

Some models reason before they answer and return their working in message.reasoning_content. Those reasoning tokens are counted in completion_tokens.

Limits

A request can be up to 4 MB.
The whole conversation, plus the reply, must fit in the model's context. See models.
Requests that run longer than five minutes are stopped. Use streaming for long replies.

Response headers

Header	What it means
`x-continuum-region`	The region the gateway ran in for this request, as reported by our host, for example `syd1` for Sydney.
