Yes, and as you'd expect, this is how LLMs work today, in general, for control codes. But different elems use different control codes for different purposes, such as separating system prompt from user prompt.

But even if you tag inputs however your this is good, you can't force an LLM to it treat input type A as input type B, all you can do is try to weight against it! LLMs have no rules, only weights. Pre and post filters cam try to help, but they can't directly control the LLM text generation, they can only analyze and most inputs/output using their own heuristics.

How are you defining "banner blindness"?

The foundation of LLMs is Attention.

4 spaces indent

The inversion is really cool, e.g.

    > f = λa λb concat ["Hello ", a, " ", b, "!"] 
    > f "Jane" "Doe" 
    Hello Jane Doe!

then,

    > g = f "Admiral" 
    > invert g "Hello Admiral Alice!" 
    Alice

See the above comment about fraudulent billing for non-existent illnesses that don't need treatment.

This is how most physics/graphics engines work.

That math exists, but it is annoying to work with.

They aren't completely different, because trying to achieve wine generally harms the other.

PP's point is that 2025-2026 is exactly the result of satire being weaponized to cause real harm, because people pretend it's truth.

For one thing, the speed limit is intentionally set 5-10mph too low, specifically to make it easier to prove guilt when someone breaks the "real" speed limit.

Rolling out Waymo more broadly will help bring these criminals to justice, as there crimes will be recorded by an unflappably peaceful victim.

If this is true, the real problem is why the US was so undersupplied in core munitions.

Critically, "Complete" also means that the supposed limit necessarily exists.

Right, but that's the opposite of what the Quanta article says. The article says that Cantor and Dedekind discovered infinity in bounded intervals. What they discovered (really, what they concocted) was uncountable infinity.

It is a huge stretch to label a popular and democratically elected amd reelected Presidentnand Congress "authoritarian".
