alt Hacker NewsApologies, I tend to use web chats and agent harnesses a lot more than raw LLMs.
Strictly for raw models, most now do train on chain-of-thought, but the planning step may need to be prompted in the harness or your own prompt. Since the model is autoregressive, once it generates a thing that looks like a plan it will then proceed to follow said plan, since now the best predicted next tokens are tokens that adhere to it.
Or, in plain english, it's fairly easy to have an AI with something that is the practical functional equivalent of intent, and many real world applications now do.
You realize the generation of the "Chain-of-thought" is also autoregressive, right?
It's not a real reasoning step, it's a sequence of steps, carried out in English (not in the same "internal space" as human thought - every time the model outputs a token the entire internal state vector and all the possibilities it represents is reduced down to a concrete token output) that looks like reasoning. But it is still, as you say, autoregressive.
And thus - in plain english - it is determined entirely by the prompt and the random initial seed. I don't know what that is but I know it's not intent.
