Introducing Claude Opus 5. It's a thoughtful and proactive model that comes close to the frontier intelligence of Fable 5 at half the price.

Lesson: Half-price near-frontier models expand who can run agentic daily work at scale.

it's one click in buzz to make a local model available to agents AND share your compute with other people. just one. and your agents will automatically chose the largest/best shared model available.

Lesson: Local model → agent bus + optional shared compute is the P2P inference UX labs still lack.

Banning open-source AI would hurt defenders 10x more than attackers, which would make the world 10x more dangerous and this is a good example why!

Lesson: OSS AI bans asymmetrically disarm defenders while attackers already bypass hosted guardrails.
