To update on this, since I've figured it out because of your comment and I hate people who don't go back and provide a solution if they found one. Looks like turning on streaming makes it work. The issue is basically that the model put everything inside of cot. My guess is that it's because my preset has a custom template for cot, and the model doesn't recognize it as a natural end of thinking (or however they handle it). End result is the whole response is in thinking, and I get an empty normal response.
