I'm one of the recipients of the AI grants, to support my work at fast.ai. I'm extremely grateful to a16z for their support. Here's some additional details based on questions I see in the comments:
My grant covered the purchase of a Scalar server from Lambda Labs, which allowed me to configure a system with 8 previous-gen A6000 GPUs, partly also thanks to NVIDIA who has recently given me 3 of those cards, and Lambda Labs who offered to provide everything at cost.
a16z didn't ask for any equity or any kind of quid pro quo, other than to let folks know that they provided this grant. They couldn't have been more helpful through the process - I didn't have to fill out any forms (other than sign a single one page agreement), the contract was clear and totally fair (even explicitly saying that a16z wasn't going to receive any kind of rights to anything), and they wired me the money for buying the server promptly.
