> But can your PDF run an AI agent?

Oh it's so much worse than that. Your font can run an AI agent.

Llama.ttf: A font which is also an LLM -- https://news.ycombinator.com/item?id=40766791

In my opinion the question isn’t so much “if” but rather “when”.

When will AI research and hardware capabilities reach a point that it’s practical to embed something like that into a regular document?

We’ve already seen proof of concept LLMs embedded into OpenType fonts.

I guess the other question is then “what capabilities would these AI agents have?” You’d hope just permission to present within that document. But that depends entirely on what unpatched vulnerabilities are lurking (such as the Microsoft ANSI RCE also featured on the HN front page)

    For Chrome's PDF renderer, the runtime is V8, so we're literally one (hilarious) line of code away from this glorious future existing today:

      You could write an LLM in plain JS, right?

        Yep, but one without the ability to even JIT down to vectorized CPU commands (to say nothing of GPU connectivity) would be incredibly slow indeed!

Looking forward to a day when you may not have a powerful enough GPU to open a PDF

The first widespread AI Malware will be a historic moment in this century. It will adapt like a real biological virus to its host and we have no cure for this.
