    All that keeps jumping out at me is how they've set it to refuse giving users thinking tokens and prompts for full reasoning in output. Just drives me further away; I may not stop using Claude completely for now, but I'll be moving even more of my primary workload to Chinese providers. That's where openness and freedom is now at.

      I keep seeing comments added to code, which reads like reasoning output instead of meaningful words. I see this behavior for both OpenAI and Anthropic models (for several harnesses as well).

      But this is a sample of one. And I may be in a situation where I'm more negative to the output from LLMs in general.

        Yeah GPT 5.6 models did it a lot and Opus is absolutely awful on this. It's clearly encoding it's thinking/context into the comments. GPT-6 models seem to be better about it.

          Are we talking, like, a ton of verbose comments? Because “what were you thinking here?” is kinda-sorta what I want in comments. As opposed to the old “telling me what I can already see.”

            Think 6 lines of verbal diarrhea on a constant definition
