This is exactly it. A human capable of reasoning might not know how to write code. But they can learn and be taught. Eventually, you can give them a vague problem, and they’ll know what clarifying questions to ask and how to write the code. LLMs cannot do that.

If you have to do the reasoning and tell the LLM the results of your reasoning before it can generate the code you want, surely that tells you the LLM isn’t reasoning. Agentic workflows hide some of it, but anyone who’s interacted even a little with an LLM can tell they’re not reasoning, no matter how OpenAI and Anthropic label their models.
