Honestly I thought you guys had launched already (and didn't know you were a part of YC), been aware of you guys for years now it seems. Congrats on the launch! Hope the twitter issues aren't causing you guys too many problems.

Normally I'd send this as a DM or email, but I think it could be useful for others to learn about how to use your service/the limitations of it. A couple weeks ago I made a search for:

    In early 2023, Andrej Karpathy said something like "large training runs are a good test of the overall health of the network." Something something resilience as well I think. I need you to find it.

Unfortunately it wasn't able to find it, but it was either in a tweet or a really long presentation, neither of which are good targets for search. It was around the same time that this (https://www.youtube.com/watch?v=c3b-JASoPi0) video was posted, like within a couple weeks before or after. How could I have improved my query? Does exa work over videos?

I think I found it! Unfortunately we do not include tweets in our search index

> TLDR LLM training runs are significant stress-tests of an overall fault tolerance of a large computing system acting as a biological entity.
