This Week In Startups is made possible by:Superhuman: https://superhuman.comSentry: https://sentry.io/twistLightfield: https://lightfield.appToday'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.GuestsAllan Guo on X: https://x.com/_allanguoWillow: https://willowvoice.com/Ethan Goodhart: https://x.com/EthanGoodhartSign up for the Wind TestFlight: https://testflight.apple.com/join/zZqmhhwfRelevant LinksCNBC: OpenAI "will be a public company in 2027": https://www.cnbc.com/2026/08/19/open-ai-ipo-timing-2027-friar.htmlOpenAI Zero Data Retention Pledge: https://openai.com/index/our-commitment-to-zero-data-retentionTWIST (June 2026): Jason comments on OpenAI and training data: https://youtu.be/o3eow1nTrcI?si=orungk7OmplOuyio&t=742All In podcast (Feb 2023): Jason comments on open source vs. frontier models: https://youtu.be/PVgBWV2bvLs?si=j6y7sHS0wx9q09oa&t=5173Harvey: https://www.harvey.ai/Harvey Tenet Research Preview: https://www.harvey.ai/blog/post-training-update-harvey-tenetFireworks AI: https://fireworks.ai/Wispr Flow: https://wisprflow.ai/Pipedrive: https://www.pipedrive.com/Nvidia Jetson Thor: https://www.nvidia.com/en-us/autonomous-machines/embedded-systems/jetson-thor/OpenAI shares Wind golf cart clip: https://www.tiktok.com/@openai/video/7645336713472134431Starlink Mini: https://starlink.com/mini-product-us?srsltid=AfmBOorzM7arxhdzYAdDpH6RGD4LLg9WV_BFnEoLuYieuHuGSCjQTE1YToro mowers: https://www.toro.com/404 Media: https://www.404media.co/Punchbowl News: https://punchbowl.news/Semafor: https://www.semafor.com/Skift: https://skift.com/Newcomer: https://www.newcomer.co/Deirdre Bosa on YouTube: https://www.youtube.com/@deebosaElectrek: Genesis GV90 review: https://electrek.co/2026/08/20/genesis-gv90-luxury-coach-doors-images/Toyota Alphard gallery: https://global.toyota/en/mobility/toyota-brand/gallery/alphard.htmlThe Clash "London Calling" video: https://www.youtube.com/watch?v=EfK-WX2pa8cTimestamps:Subscribe to the TWiST500 newsletter: https://ticker.thisweekinstartups.comCheck out the TWIST500: https://www.twist500.comSubscribe to This Week in Startups on Apple: https://rb.gy/v19fcpFollow Lon:X: https://x.com/lonsFollow Jason:X: https://twitter.com/JasonLinkedIn: https://www.linkedin.com/in/jasoncalacanisCheck out all our partner offers: https://partners.launch.co/Great TWIST interviews: Will Guidara, Eoghan McCabe, Steve Huffman, Brian Chesky, Bob Moesta, Aaron Levie, Sophia Amoruso, Reid Hoffman, Frank Slootman, Billy McFarlandCheck out Jason's suite of newsletters: https://substack.com/@calacanisFollow TWiST:Twitter: https://twitter.com/TWiStartupsYouTube: https://www.youtube.com/thisweekinInstagram: https://www.instagram.com/thisweekinstartupsTikTok: https://www.tiktok.com/@thisweekinstartupsSubstack: https://twistartups.substack.com
