Is the OpenAI API Temperature Range 0–1 or 0–2?

Want to use over 200+ MCP servers inside your coding tools like Cursor?
I noticed that the official API docs (OpenAI API) state that the temperature parameter accepts values from 0 to 2.
However, everything I’ve read so far—and even the slider in the Playground—suggested a range of 0 to 1. Is this a recent change, or has the API always supported 0 to 2 with the Playground simply optimized for common usage?
Any clarification on this discrepancy would be appreciated.

Based on the documentation, the temperature parameter has always been defined as accepting values between 0 and 2. The API docs consistently state that the full range is from 0 (more deterministic) to 2 (more random), with a default value of 1.
The slider in the Playground may appear to suggest a 0-to-1 range, but that interface might be optimized for common usage rather than reflecting the full, technically allowed range. In practice, you can set the temperature anywhere between 0 and 2 in your API requests.
So, no, it doesn't represent a recent change; it's been that way in the API documentation, even if many external sources have often referred only to the 0–1 portion of the range.
