Totally deserved. Rock on Anthropic

Open article: Anthropic turns the tables on OpenAI in critical revenue category by axios.com

A line chart that shows monthly shares of first-time enterprise customers choosing OpenAI or Anthropic from December 2025 to February 2026. OpenAI fell from 59.7% to 26.7%, while Anthropic rose from 40.3% to 73.3%.

There's a 90% chance that you're browsing linkedin right now because Claude is down. #iseeyou

There's a 10% chance that one of your colleagues is having a heart attack right now because of it

Yes, I'm still alive. In other news, I almost subscribed to Whisper today. Almost. My Obsidian vault says I went down from 45 Subscriptions for business-related services to 12 in the past month.

Will write about it soon and probably a bit more when I'm done being completely exhausted from working, AI, context managing (keeping 1'000 md files under control, probably the most elegant thing i ever built in my life), and sleeping too little.

Anthropic, you guys are rocking it.

Also, I created a knitting/stitching app for Taylor Swift fans with Claude, and the people who use it are loving it. Don't ask, still proud.

Ciao.

Using Lovable for the first time for fun, after playing adult in Claude code for 3 weeks straight.

Can you tell that I'm a prompt engineer?

Pretty good stuff there Elena Verna, you should try it out too. Claude is commenting my efforts with:

"Oh Leah, Lovable doesn't know you like I do, I know what drama really means for you."

Immediate promotion.

(Lovable is cool though, can see how it's good with a context machine behind it, that feeds great plans)

I caught the same wrong fact in three different reports last week.

Numbers were correct. Charts were clean. Conclusions were garbage.
The date range included bot traffic. Nobody flagged it. The knowledge that those weeks were polluted? Lived in my head.

My AI caught it. Because I taught it that fact three weeks ago in one line of text.

FFS, we're spending billions optimizing retrieval. Bigger context windows. Better RAG. Faster inference.

Nobody is asking whether the fact being retrieved is actually true.
Retrieval correctness is not factual correctness.

The fix isn't a better model. It's a text file where you write down what you already know. 30 seconds. One correction. Every future output gets better.
I wrote about how I actually do this, why I think about reports like code commits, and the Sisyphus problem of building context.
