# thinking_not_supported

**HTTP status:** 422 (Unprocessable)

**Title:** Thinking cannot be turned off

## Cause

The model in `llmConfig.model` cannot turn thinking off, so `thinking: "off"` is rejected. `GET /v2/models` says which models accept it.

## How to fix it

Send thinking adaptive, or remove thinking, for the model in this field.

Set the parameter named below and send the request again.

Every error carries `requestId` and the `Request-Id` header. Send it when you write to support.
