What’s the future of AI code generation? This week on Mixture of Experts, host Tim Hwang is joined by Chris Hay, Olivia Buzek and Gabe Goodhart to debrief the biggest AI use-case of 2025: AI-powered software engineering.  

Claude Opus 4.5  solved a months-long optimization in under an hour but failed spectacularly at simple tasks. The barbell effect is real. Next, who's the architect—you or the model? We discuss agent orchestration, context windows and why tool performance varies wildly. Then, model differentiation: are OpenAI and Anthropic fundamentally different, or does agent architecture matter more? Finally, can open-source compete with closed ecosystems? We explore vertical integration, inference costs and the future of open models. All that and more on this week's Mixture of Experts.

Should we care about GPT-5.2? This week on Mixture of Experts, we analyze the “code red” release of GPT-5.2 as OpenAI responds to Gemini 3. Are the constant model drops benefitting consumers? Next, Stanford released their Foundation Model Transparency Index, revealing a troubling trend that most labs are becoming less transparent. However, IBM Granite achieved a 95/100 score. Then, our experts discuss what model transparency means for enterprise AI adoption. Finally, we debrief AWS re:Invent’s biggest announcements, including Nova frontier models and Nova Forge. Join host Tim Hwang and panelists Kate Soule, Ambhi Ganesan and Mihai Criveti for our expert insights.

Is open source winning the AI race? This week on Mixture of Experts, we analyze three major model releases that dropped in the final weeks of 2025: Mistral 3, DeepSeek-V3.2 and Claude Opus 4.5. Our experts discuss what makes each model unique—from Mistral’s multimodal capabilities to DeepSeek’s reasoning-first approach and Claude’s developer focus. Are there too many good models?  

Next, a provocative blog post from Theory Ventures argues Gemini 3 proves scaling laws are throwing more compute at the problem. We debate if scaling laws are a universal truth.  

Finally, Amazon just blocked ChatGPT’s shopping research agent from accessing product data. We discuss the business incentives threatening the agent dream.  Join host Tim Hwang and panelists Aaron Baughman, Abraham Daniels and Gabe Goodhart on this week’s Mixture of Experts for more! 

00:00 – Intro 

02:05 -- Model launches: Mistral 3, DeepSeek-V3.2 and Claude Opus 4.5

Will Black Friday 2025 be the breakout moment for agentic commerce? This week on Mixture of Experts, we're departing from our usual format for a Thanksgiving special focused entirely on AI agents. Host Tim Hwang is joined by Chris Hay, Lauren McHugh Olende and Volkmar Uhlig to debate whether 2025 is truly the "year of agents." Our experts break down why consumer-facing agentic commerce still faces major hurdles. We also explore the massive gap between building agent prototypes and deploying them at scale and discuss why the developer ecosystem needs a "Shopify moment." Then, could language-to-agent interfaces bypass traditional development entirely? From coding agents like Claude Code to cost optimization challenges, this episode covers what needs to happen for agents to move from POC to production. And finally, who's positioned to dominate the space?  

Plus: Anthropic dropped Claude 4.5 Opus this week. We sit down with Mihai Criveti to discuss initial impressions of the new model. Does this put Anthropic back at the top of the AI game?
