Can I see what Max or Heavy is thinking?

On the Model API, Max and Heavy return their reasoning as reasoning_content (on the message, or delta.reasoning_content when streaming), separate from the answer in content. It's billed as output tokens. Flash has no extended thinking, so there's nothing to show. See reading reasoning in Python.
