The current approach is to use delimiters that are special tokens that can't be represented in regular text: https://github.com/openai/harmony/blob/main/docs/format.md#s...
Then you train your model to take those tokens into account.
Which sounds promising... until you see results like this one: https://arxiv.org/abs/2603.12277
> We trace prompt injection to role confusion: models perceive the source of text from how it sounds, not its labeled role. A command hidden in a webpage hijacks an agent simply because it sounds like <user> text, despite its <tool> label
We have even observed that the most effective LLM usage is when paired with an expert in charge of the goals. Dark factory and other automated harnesses (specs engineering and what not) seem to be a dead end. The most impactful approach to this date is an interactive conversation as a succession of small and verifiable tasks.
The absolute most I've seen from you in response to an extensive teardown of your argument, supporting evidence, and subsequent conversational judo was a «Wow. That was well phrased.» and no subsequent change in your publicly-expressed opinions.
I'd do more than gesture at the relevant lesson taught to us by Google Fiber, Tesla, SpaceX, etc., but you'd not be publicly moved, so it's a waste of time.
Justify that.
Also, which "extensive teardown" are you talking about there?
