Episode notes
This Week In Startups is made possible by: Paypal Open Today’s show: On a podcast this week, Sam Altman made a bold declaration: “We are now, like, in the singularity.” A bold claim which Alex puts bluntly to this week’s panel. Grant Lee of Gamma and Philip Johnston of Starcloud sound off… Is this actually the Singularity, and if so, why do things still feel so normal? Plus the panel and guest host Alex Wilhelm discuss the infrastructure and economics that will make singularity-scale AI buildout possible… NVIDIA’s strongly worded letter about open-weight models… Moonshot’s new Kimi K3 twist…

Anthropic is training to destroy your company | EP 27
This Week In AI is made possible by: PayPal - Pay zero processing fees on your first $100K in eligible PayPal payment volume. Learn more at paypal.launch.co Today’s show: *On “All In,” Gavin Baker said that Anthropic leadership privately believes that it could one day become “the only private company in the world.” The ensuing street fight on X turned into a referendum on doomerism, the nature of regulatory capture, and why the public hates AI so darn much. Jason’s take: If a frontier lab really believes they’re destined to be the world’s only company, they’re studying your data and planning…

Why Anthropic is watermarking every word Claude writes | E26
This Week In AI is made possible by: Paypal Open Today’s show: Anthropic’s new Claude watermark travels around any and all copy-and-pasted text. Is this a logical response to AI slop, or more overreach from those regulation-loving Europeans? The panel agrees that identifying AI outputs has a place, but divides on how the world should get there. PLUS everyone’s favorite section of Mark Zuckerberg’s 6500-word techno-optimist AI manifesto, exploring the frontier labs’ blatant hypocrisy around distillation, and why Texas is hitting the pause button on 474 GW of proposed data centers. Guests:…

Is open source AI really ahead of the frontier? 3 builders weigh in. | E25
This Week In Startups is made possible by: PAYPAL OPEN Today’s show: China’s Alibaba just dropped a 2.4 trillion parameter open weight model that the company claims only trails Anthropic’s flagship among the major frontier rivals. Of course, this happened the very same week that the US government appears to have backed off from banning these models stateside entirely. Are these models anywhere close to actually catching up to the latest and greatest releases from US labs like Anthropic and OpenAI? Really seems to depend on who you ask. (Even long time friends JCal and Elon Musk can’t see eye…

America already lost one AI race | TWiAI Ep 23
This Week In Startups is made possible by: PAYPAL OPEN Today’s show: This week, our panel of AI experts — Anand Kannappan (Patronus AI), Ori Goshen (AI21 Labs), and Alex Finn (Henry Intelligent Machines) — join special guest host Lon Harris to debate whether Washington will move to formally limit powerful foreign AI models like Moonshot’s Kimi K3 and Z.ai ’s GLM-5.2. What does “winning the AI race” actually mean on a practical level? Why is cybersecurity, not benchmarks, likely the actual battleground. And why did Hugging Face have to use GLM-5.2 to investigate their recent breach rather…

Grok 4.5 and GLM-5.2 kick off Token Price Wars | E22
This Week In Startups is made possible by: PAYPAL OPEN Today’s show: The price of tokens keeps tumbling down, and it’s changing who controls AI. Grok 4.5 and GLM-5.2 landed within two weeks of one another, offering powerful alternatives at a fraction of frontier prices. But are SpaceXAI’s latest offering and open weight models truly ready to replace Opus, GPT-5.5, and Fable? Are enterprises finally ready to stop renting and start owning their intelligence? On TWiAI Episode 22, Jason and Lon welcome three top founders — Sara Hooker (Adaption Labs), Manu Sharma (Labelbox), and Spiros Xanthos…

What happens if China pulls the plug on open-source AI? | Ep 21
This Week In Startups is made possible by: PAYPAL Today’s show: China is weighing a ban on foreign access to its top AI models… the same low-cost open-weight systems on which half of the Valley’s startups are building. So we asked our two all-star panelists — Arena CEO/Co-Founder Anastasios Angelopoulos and Hippocratic AI CEO/Co-Founder Munjal Shah — what happens to US companies when their favorite cheap, powerful models vaporize overnight. PLUS why Hippocratic runs 31 models in parallel to ensure clinical-grade safety, the latency-vs-intelligence tradeoff no one is optimizing for, and why a…

Data Centers Aren't Killing the Grid. They Could SAVE It.
Thanks to our partner, @Paypal! Pay zero processing fees on your first $100K in eligible PayPal payment volume. Learn more at https://paypal.launch.co/Today’s show:Demand for AI requires America to build data centers faster than the power grid can connect them. Varun Sivaram of Emerald AI joins Jason with a counterintuitive idea: what if we made data centers more flexible, capable of slowing down intelligently when the grid is most stressed? (That only happens a few hundred hours each year.)PLUS, Vibhav Viswanathan of Pascal AI demos his product, which gives AI agents working for hedge funds…

This Week In Startups is made possible by:PayPal: https://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…

Why OpenAI Should Buy Off the World’s Top Mathematicians | E32
This Week In Startups is made possible by: PayPal - Pay zero processing fees on your first $100K in eligible PayPal payment volume. Learn more at https://paypal.launch.co Today’s show: OpenAI is claiming to have solved more than 100 math problems on top of Navier-Stokes, and guest Richard Socher thinks it's absurd for mathematicians to push back on AI solving their problems too quickly. Jason and Lon are also joined by Guy Podjarny of Tessl and Jake Loosararian of Gecko Robotics to argue over who wins when AI agents start collaborating with, and potentially replacing, academics and scholars.…

The biggest AI threat still comes from humans | E31
This Week In Startups is made possible by: PayPal: paypal.launch.co Today’s show: Dario Amodei and Sam Altman are apparently scared of AI models going rogue. Swarms of agents spontaneously deciding to copy themselves over to thousands of computer systems and plot world domination. Our panelists this week — Kevin Mandia (Armadin) and Soups Ranjan (Sardine AI) — investigate real AI-based attacks every single day, and they suggest we’re hyping the wrong concerns. The actual danger isn’t coming from an AI system that turns hostile. It’s human beings, like criminals, using AI to drain your bank…
