Today's show:

Jason's been saying it for years now (and we've got an All In clip from 2023 to prove it). Open source will win the AI race. This week gives us a major evidence point, as $11B legal AI company Harvey released its own in-house model, trained on an open-weight Kimi K3 base. Harvey made a proprietary specialized solution without having to risk sharing its precious expert-compiled data with the major frontier labs.

PLUS we're checking out the FREE AI dictation app Willow with co-founder Allan Guo, and finding out how he plans to compete with giants like Wispr Flow and Apple. AND we've got the Stanford student who built an automated golf cart and gave luminaries like Jensen Huang and Sam Altman rides around campus.
