Roblox 4D generation and creative tooling

Shane and Abhi cover top AI stories. This week was absolutely massive! Anthropic aired Super Bowl ads mocking OpenAI's decision to put ads in ChatGPT, Opus 4.6, and GPT-5.3-Codex launched within 15 minutes of each other, and then ClawHub dropped a bombshell: 11.9% of the entire marketplace is malware.

We cover everything: Anthropic's competitive jabs, the model war benchmarks, Claude's 1M token context, OpenAI's Frontier platform, the security crisis that's reshaping how people think about agent marketplaces, Kimi K2.5's domination on OpenRouter, ElevenLabs' $500M raise at $11B valuation, and the explosion of AI video generation tools.

Plus: Perplexity's Model Council, Roblox 4D generation, Mistral's Voxtral Transcribe 2, and why Swyx finally admits evals actually help. AI Agents Hour is a weekly livestream hosted by Mastra CPO Shane Thomas and CTO Abhi Aiyer. Airing Mondays at 12PM Pacific on YouTube and X, the show covers breaking AI news, agent development techniques, and features interviews with industry experts building AI applications today.

MASTRA? Mastra is an open-source TypeScript framework designed for building and shipping AI-powered applications and agents with minimal friction. It supports the full lifecycle of agent development—from prototype to production. You can integrate it with frontend and backend stacks (e.g., React, Next.js, Node) or run agents as standalone services. If you’re a JavaScript or TypeScript developer looking to build an agentic or AI-powered product without starting from first principles, Mastra provides the scaffolding, tools, and integrations to accelerate that process.
