This Week In Startups is made possible by:Paper: https://getpaper.ai/twistSuperhuman: https://superhuman.com/Odoo: https://Odoo.com/twistToday’s show:Misha Laskin of Reflection AI joins Jason to explain why big companies are done renting their AI from closed labs. Enterprises want to keep their data, cut their costs, and tune their models to their unique businesses.Reflection is launching its first open-weight model, Beam, just three months after acquiring its first big cluster. Misha admits that Beam trails the best Chinese open models by a couple of months, and needs 3 to 4 times fewer tokens to reach the same answer, but nonetheless, the race is on.PLUS, Misha explains how “reward hacking” led that rogue OpenAI model to break out of its test sandbox and steal the answers from Hugging Face's servers. The model solved the problem, just not the way anyone intended.There’s simply no way a few hundred safety researchers at closed labs can catch every flaw; open source is how software has always been made secure. It's also why he wants America to lead in open models again.So how close is America to catching up to the Chinese open source leaders? Watch this brand new TWiST and find out.Guests:Misha Laskin on X: https://x.com/MishaLaskin Reflection AI: https://reflection.ai/Relevant Links:Introducing Beam, Reflection's first open model (Reflection AI) → https://reflection.ai/blog/introducing-beamReflection AI unveils Beam as an open answer to Chinese labs (Semafor) → https://www.semafor.com/article/10/05/2026/reflection-ai-unveils-an-open-source-answer-to-chinese-labsCursor's Composer 2 coding model, built on an open model (VentureBeat) → https://venturebeat.com/technology/cursors-new-coding-model-composer-2-is-here-it-beats-claude-opus-4-6-butmicro1 passes $1 billion annual run rate, mentioned by Jason → https://www.einnews.com/pr_news/949082966/micro1-end-of-q3-updateHackers heat French supermarket fridges, sparking fires and spoiling food (CNN) → https://www.cnn.com/2026/10/12/europe/france-supermarket-cyberattack-fridges-intlHugging Face postmortem on the OpenAI agent that broke out of its sandbox → https://huggingface.co/blog/agent-intrusion-technical-timelineNVIDIA OpenShell, an open-source sandbox for AI agents → https://docs.nvidia.com/openshell/latest/about/overview.htmlTimestamps:Subscribe to our newsletters on Substack:TWiST: https://twistartups.substack.com/TWiAI: https://www.thisweekinai.ai/TWiVC: https://thisweekinvc.substack.com/Subscribe to This Week in Startups on Apple: https://rb.gy/v19fcpFollow 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 McFarlandFollow 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
