Anthropic might be back. Opus 5.5 performs at Fable 5.1 level for 40% less, and Sonnet 5.5 dropped the same day we went live, beating Opus on Terminal-Bench 4. OpenAI answered with GPT-6 Sol and Luna and a rumored long-running agent called Aeon. Meta launched Muse at Connect, then hired MongoDB's CEO to lead a new enterprise platform.
Then there's safety. SNL took a shot at Dario, a report says the labs are looking into tens of thousands of incidents, and NVIDIA launched an agent safety platform with 100+ partners. We also explain why Mastra doesn't believe in model routers, and close with quick hits: Anthropic may kill plan mode, one company rebuilt Devin in two days, CI costs are exploding, and Google is sending TPUs to space.
AI Agents Hour is a weekly livestream by Mastra CPO Shane Thomas and CTO Abhi Aiyer. Mondays 12PM Pacific.
