AI Model Showdown: Grok 4.1 vs. Gemini 3 | E2211

E2211 • Nov 18, 2025 • 47 mins

Today’s show: Will the arrival of two hotly-anticipated, intensely powerful AI models snap the Doomer cycle? On a new TWiST, Jason and Alex consider the current AI landscape, one where cynicism about insider mega-deals, fear of job displacement, and concerns about bubble bursts seem to rule the day. Will the arrival of two powerful new models — xAI’s Grok 4.1 and Google’s Gemini 3 — help the industry to course-correct? And how do we decide how much these models have improved anyway? PLUS we’re investigating Cloudflare’s recent downtime and their acquisition of Replicate. Are we heading toward a future in which everyone runs their own models, locally? And how worried should founders get if their products or sites go down for a few hours? Finally, if you’re an investor, and want to come to Jason’s Dim Sum Demo Day in San Francisco, here’s the link: http://launch.co/dimsum

Key Points

  • Grok 4.1's release demonstrates significant advancements in AI, particularly in reducing hallucinations and improving performance metrics, underscoring the competitive progress among US AI labs.
  • Cloudflare's recent outage highlights the dependency of startups on cloud services and the importance of having effective communication and mitigation strategies for downtime.
  • Anthropic's substantial investments from Microsoft and NVIDIA, alongside their commitment to purchase significant Azure compute capacity, indicate a strategic move towards solidifying their position in the AI ecosystem and ensuring broad accessibility across major cloud platforms.
