AI Solves an 80-Year Mystery, Microsoft Agents Take Over, & Anthropic’s Claude Mythos vs. Fable | 138

Send us Fan MailIn this episode of Sidecar Sync, Amith and Mallory explore three major developments shaping the future of AI. First, they unpack how an OpenAI model independently solved a decades-old mathematical problem—challenging long-held assumptions and proving AI can generate truly novel insights. Then, they break down Microsoft Build 2026 and the shift toward an “agent-first” world, where AI systems take on real work across your organization. Finally, they dive into Anthropic’s powerful new Claude Fable model, discussing its capabilities, real-world applications, and the growing tension between performance and transparency. Along the way, they connect these breakthroughs back to what matters most for associations: data strategy, flexibility, and staying ahead in a rapidly evolving AI landscape. 🤖 Join the AI Mastermind: https://sidecar.ai/association-ai-mastermind 📕 Download the New 3rd Edition of ‘Ascend’:https://sidecar.ai/ai 🛠 AI Tools and Resources Mentioned in This Episode:Claude Fable & Mythos ➔ https://www.anthropic.com/news/claude-fable-5-mythos-5 Microsoft Build 2026 ➔ https://news.microsoft.com/build-2026/ OpenAi Solves Math Problem ➔ https://openai.com/index/model-disproves-discrete-geometry-conjecture/ Member Junction ➔ https://www.memberjunction.org LangGraph ➔ https://www.langchain.com/langgraph CrewAI ➔ https://www.crewai.com n8n ➔ https://n8n.io📅 Register for digitalNow2026 in Washington, D.C. from October 25–28:  https://digitalnow.sidecar.ai🎀 Use code AIPOD50 for $50 off your Association AI Professional (AAiP) certification at https://sidecar.ai/aaip🚀 Help Us Grow Our Reach - Share With a Friend or Colleague!👍 Like & Subscribe!https://x.com/sidecarglobal https://www.youtube.com/@SidecarSynchttps://sidecar.ai/ https://www.linkedin.com/company/sidecar-global/Amith Nagarajan is the Chairman of Blue Cypress, a family of purpose-driven companies and proud practitioners of Conscious Capitalism.
