I noticed the new GPT 5.6 models both regular and Pro are priced the same for input and output token costs. Is this right?

Yes, there is no separate price from the source API for Pro this time: https://developers.openai.com/api/docs/pricing

It's now just a reasoning setting which I suspect OpenRouter does not support natively, so another endpoint is needed.
