New Opus 4 from Anthropic Can Work a Full Day With No Human Input

Anthropic, which is OpenAI’s primarily competitor (besides Google the behemoth) in the generative AI space, just dropped a brand new model this morning: Opus 4.

It’s a hybrid reasoning model designed specifically for building AI agents.

What does that mean? Basically, Opus 4 can work an entire day or more without human input.

You can, Anthropic says, give it a task like “write a book about Bichon Frises” or “write all the code for a SaaS product that builds Bichon-friendly travel itineraries for Bay Area families”, and it will go ahead and do that.

(Okay, those aren’t actually Anthropic’s specific examples. But they are good ideas, and things Opus 4 could apparently do.)

Opus 4 is a direct challenger to OpenAI’s new Codex, and a big step towards creating genuinely helpful AI agents.
