Here are my Opus 4.5 thoughts after ~2 weeks of use.

First some general thoughts, then some practical stuff.

--- THE BIG PICTURE ---

THE UNLOCK FOR AGENTS

It's clear to anyone who's used Opus 4.5 that AI progress isn't slowing down.

I'm surprised more people aren't treating this as a major moment. I suspect getting released right before Thanksgiving combined with everyone at NeurIPS this week has delayed discourse on it by 2 weeks. But this is the best model for both code and for agents, and it's not close.

The analogy has been made that this is another 3.5 Sonnet moment, and I agree. But what does that mean?

Every few generations we get a major model unlock - a moment that unlocks a new way of working. GPT-4 was the unlock for chat, Sonnet 3.5 was the unlock for code, and now Opus 4.5 is the unlock for agents. Thanks to Opus 4.5, agents can now work reliably on increasingly longer time horizons and get real-world work done on your behalf.

Opus 4.5 is like a Waymo. You tell it "take me from A to B", and it takes you there. After a few of these experiences your brain realizes "oh. ok. we live in this world now". And then you're hooked.

From that moment on, you'll never work the same way again.

THE YEAR OF AGENTS

2025 has been touted as the year of agents, and Opus 4.5 + Claude Agent SDK is the pairing that makes that phrase true.

The Claude Agent SDK is the best open secret in AI right now. An agent's harness matters almost as much as its model. If you have a bad harness, then you may as well have a bad model. With the SDK you get a world-class agentic harness out-of-the-box which you can now pair with Opus 4.5 to build real-world agents that actually work.

I'm reminded of Alan Kay's quote "People who are really serious about software should make their own hardware". The agent version of this is "people who are serious about models should make their own harness". Anthropic clearly believes this, and it's working. The pairing of these tools is magic.

I would describe myself as being "unhobblings-pilled", and the Claude Agent SDK + Opus 4.5 is the next major unhobbling. There's now another OOM of new latent economic value stuck in this combo, and it's the job of builders to get it out.

If you were bearish on agents, now is the time to turn bullish.

"ALL OF THIS IS REAL"

"You know what's crazy? That all of this is real". This was Ilya's opening line about the state of AI in his Dwarkesh interview, and I echo that sentiment. I can't believe that Opus 4.5 is real.

There have been several times as Opus 4.5's been working where I've quite literally leaned back in my chair and given an audible laugh over how wild it is that we live in a world where it exists and where agents are this good.

Nat Friedman has this great question on his website: "Where do you get your dopamine?"

Increasingly, I get mine from Claude.

LONG ANTHROPIC

I saw a post yesterday where someone said that Opus 4.5 was the most important thing to happen to them in their professional career. This will be true for more people going forward.

Every year for the past 3 years, Anthropic has grown revenue by 10x. $1M to $100M in 2023, $100M to $1B in 2024, and $1B to $10B in 2025. In Dario's recent DealBook interview he expressed that he wasn't sure if that 10x pattern would hold for 2026.

While he's probably right, I do expect Anthropic's revenue at the end of next year to be much higher than everyone expects. It wouldn't surprise me if they passed OpenAI in valuation by early 2027.

Opus 4.5 is too good of a model, Claude Agent SDK is too good of a harness, and their focus on the enterprise is too obviously correct.

Claude Opus 4.5 is a winner.

And Anthropic will keep winning.

EU entwickelt neuen "hochmodernen" Kampfpanzer LOL - Das Konzept Kampfpanzer war schon vor 5 Jahren überholt.
Gott sei Dank werden dafür (zunächst) nur € 20m Steuergelder verbrannt.
