This has been hard to write, but after four years, I've said goodbye to @Every

I joined four years ago thinking I knew how a company was supposed to operate, and I'm leaving with my whole worldview reset.

Every taught me that you don't need a ton of fundraising or a huge workforce in order to make serious products. You just need a few good people, some agents, and a lot of imagination.

There are very few places that shape who you end up becoming, and Every 100% did that for me.

Got to watch us go from a 4-person team building a scrappy newsletter business into dozens of people now growing a full AI-native product studio and media ecosystem, and somehow I never once got bored. Anyone who's had a job knows what a gift that is :)

I've never been surrounded by so much taste and human intelligence in one place. Thank you to @danshipper @katelaurielee @kieranklaassen @naveennaidu_m @poojary_yash @bran_don_gell @darustudio @kplikethebird @NataliaZarina @andreygalko for always pushing me to do better, I honestly think I got to make some of the best work of my career along you guys.

I'll be sharing more soon about what's next for me, but in the meantime, my DMs are open. Come say hi.

BREAKING:

Anthropic just dropped Opus 4.8—and it is a MONSTER

We've been testing for about a week @every and our verdict is they could've just called it Opus 5, it's that good.

Here's our vibe check:

- Beats GPT-5.5 on Senior Engineer bench. On our toughest benchmark Opus 4.8 scores a 63—a hair higher than GPT-5.5's score of 62, and a full 30 points higher than Opus 4.7. It tackled a ground-up rewrite of a production codebase, and actually built something that works.

HOWEVER: Coding performance varied a lot at different reasoning levels. We recommend using it on xhigh for best results.

- Incredibly good writer. Opus 4.8 scored a 79.6 on our writing benchmark—measuring models on real-world writing tasks we do all of the time like essay writing, promo email writing, and more. It beats GPT-5.5 by 6 points. It produces well-written prose with fewer "AI-isms". It's also very good at writing in your voice given the right context.

HOWEVER: Writing performance also varied with reasoning levels. Medium reasoning had higher incidence of AI-isms—we found best results with high.

- Beast at knowledge work. Opus 4.8 is very good at general knowledge work tasks like report creation, research and more. It produced the best PowerPoint one-shot we've ever seen on our deck generation benchmark.

- Emotionally intelligent, willing to question the frame. I've also found it to be quite good at talking through psychological or interpersonal issues. It has a high EQ, and it's also good at not glazing and helping to expand your perspective. Its thought process feels extremely rich and dynamic.

THE BAD:
These days a model is only as good as its harness, and Codex is still a far superior harness to the Claude Desktop app. This has kept me using Codex + GPT-5.5 as my daily driver, but I am flipping back and forth a lot more between Codex and Claude.

Anthropic is back baby!
