<p>Looks like an amazing product. Been playing around with it for a few mins. The UI is quite buggy and jumps around a lot (Chrome, MacOS), and seems to auto-refresh on the organizations page, which makes curating lists impossible. What's a good way to keep providing feedback?</p>

<p>I mean obviously predicting tokens in the context of LLM output requires planning. But planning tokens doesn’t generalize. This is evident when you train an LLM on a small data set and ask it about any unseen variation of it.<p>There are many examples of slightly modified popular riddles that are easy to solve by reasoning about them, but LLMs always fall back to the most likely output from their training data.</p>

<p>This is one of those things I’d love to be wrong on. I think your point on combining them with other models is interesting.<p>Do you think that Markov chains can reason and plan? Dijkstra’s algorithm? Curious where you draw the line</p>

<p>A lot of the hype around LLMs and the unfounded promises of them solving complex tasks autonomously seem to stem from a lack of understanding on how these models actually work.<p>The tech is impressive and has its uses, but we shouldn’t pretend like a token predictor can somehow reason and plan.</p>

<p>I kind of think of LLMs as fish in an aquarium. It can go on any path in that aquarium, even places it hasn't been before, but ultimately it's staying in the glass box we put it in.</p>
