INFORMAZIONI SU QUESTO EPISODIO
Shane and Abhi are in person at the CodeRabbit studio, and AISI just quietly torched one of Anthropic's loudest narratives. AISI confirmed GPT-5.5 is the second model to complete a multi-step cyber attack simulation end-to-end. The first was Mythos.
David Cramer calls TUIs "caveman shit." Kenzie at Browserbase builds an agent in under ten minutes that ranks every SF tech event by free food probability. Codex ships Tamagotchi-style pets. Apple accidentally leaves CLAUDE.md files in a support app update.
Cursor releases its SDK. OpenCode 2.0 becomes embeddable. Matt Pocock drops Sandcastle. Warp goes open source. The harnesses are becoming frameworks, and the frameworks are growing harnesses.
Anthropic Ships connectors for Blender. Claude Security enters public beta. /goal lands in Codex CLI as OpenAI's take on the Ralph loop.
OpenAI says GPT-5.5 is its strongest launch yet — API revenue 2x faster than any prior release, Codex revenue doubling in seven days.
Vasuman posts an essay on why building real agents is harder than the hype suggests.
Open weights keep closing the gap. Kimi K2.6 beats Claude, GPT-5.5, and Gemini at a programming contest. Qwen3 6.27B takes the open weights crown under 150B parameters. Mistral Medium 3.5 lands as a 128B dense model with 256k context.
GitHub has a rough week. Wiz Research discloses an RCE achievable with a single git push.
Agents are becoming customers. Stripe Link is the wallet for agents. Cloudflare lets agents start paid subscriptions. Doola and Replit will form a US LLC inside the chat.
RAMP's coding agent now writes 70% of merged PRs. DeepSeek's input cache is 10x cheaper. Node 20 hits EOL, Zod prepares to drop CommonJS, and TypeScript native previews ship.
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.
