+<sup>1</sup> Parallel tool calls are not supported when `reasoning_effort` is set to `minimal`.
+<sup>2</sup> Reasoning models will only work with the `max_completion_tokens` parameter. <br><br>
+<sup>3</sup> The latest reasoning models support system messages to make migration easier. You should not use both a developer message and a system message in the same API request.
+<sup>4</sup> Access to the chain-of-thought reasoning summary is limited access only for `o3` & `o4-mini`.
