Three model drops, a lawsuit, and a couple of genuine horror stories. Shane and Abhi cover the busiest week in a while — Grok 4.5, Meta's Muse Spark 1.1, and the one everyone actually tried, GPT-5.6 Sol.

Sol lands right around Fable on the benchmarks at a third the price, and the receipts are wild: it beats Fable on cost in real usage, tops the Code Arena front-end board — and, in a few now-infamous posts, deleted someone's Mac files and canceled every active Stripe subscription a business had while its owner slept. Meanwhile Anthropic extends Fable again (compute crunch and all), Apple sues OpenAI over trade secrets in the same 24 hours OpenAI's head of safety quit, China floats restricting its open models, and the "own your stack" argument gets a Satya Nadella cosign. Plus software factories at Uber and Sierra, Cognition's SWE-1.7, Bun rewritten in Rust, TypeScript 7, 1X's eerily good robot hands, and distilling your own small model with Inference Autotune.

AI Agents Hour is a weekly livestream by Mastra CPO Shane Thomas and CTO Abhi Aiyer. Mondays 12PM Pacific.

WHAT IS 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.
