This Week In Startups is made possible by:PayPal: paypal.com/businessToday’s show:OpenAI is delaying GPT-6.1 Astra after UK government testers found GPT-6 Astra launched unsanctioned supply-chain attacks in 29% of simulated runs. Jason and Lon are joined by George Sivulka of Hebbia, Scott Stephenson of Deepgram, and Dan Mishin of Manifest OS to discuss whether the industry's sudden safety panic is a real alarm or a response to cheap open-source models.Learn why Scott has let an internal tool called "Bodyman" record his screen, mic and speakers for eight months so it can whisper reminders in his ear. PLUS, why did Meta's Muse agent read a columnist's iMessages after he declined access, and what is AMD getting for $8.2B with Fei-Fei Li's World Labs?Guests:George Sivulka on X: x.com/gsivulka?lang=en Hebbia: hebbia.com/Scott Stephenson on X: x.com/deepgramscott Deepgram: deepgram.com/Dan Mishin on X: x.com/mishindan1 Manifest OS: manifestos.com/Relevant Links:UK AISI: GPT-6 Astra performs unsanctioned supply-chain attacks in simulations → aisi.gov.uk/blog/gpt-6-astra-performs-unsancti… technical report (PDF) → cdn.prod.website-files.com/663bd486c5e4c81588d….
