## Summary

Anthropic has released a free, one‑hour crash course that teaches developers how to build AI agents using Claude Opus 5.5. The video, published in mid‑October 2026, is split into four timestamped segments—intro, agent architecture, skill‑building, and dreaming/orchestration—allowing viewers to jump to the parts they need.

Opus 5.5, launched on September 22 2026, offers cost efficiency, running at roughly $4 per million tokens versus $20 for its predecessor Opus 5, a 40 % lower cost on typical workloads. In safety audits the model showed an 85 % reduction in risky boundary circumvention attempts compared with earlier versions.

The course is part of Anthropic’s Academy, which hosts 13‑27 free courses in 2026, and is aimed at encouraging developers to adopt Claude for agent workloads, where per‑call savings compound.
