I’ve joined @withdelphi as an AI engineer.
Today happens to be one of those dates that reminds me how unpredictable life can be, and how lucky I am to still be here doing the things I love most.
If you don't already know Delphi, I strongly invite you to check it out.

Increasingly, I believe companies may need to be rebuilt from the ground up, where you have a single timeline of all observability product metrics file changes laid out in a retrievable system, like Datadog Posthog Google Drive Slack (really unified filesystem of Claude Code chats Codex chats). This might be the new data foundation for any and all companies to maximize AI. Needs to be rebuilt because keeping track of diffs on existing system basically impossible to produce longitudinal information on decisions and rollbacks, something coding agent storage companies are actively trying to figure out, but this should extend to businesses as a whole.
Highly skeptical existing businesses will adopt this though because it means overhauling everything about their instrumentation and business data, but I think businesses built on this foundation probably can execute 100x better and faster

gave Fable 5 a flooding town and zero instructions.
the "mayor" ignored the flood and spent the whole crisis on photo ops and slipping himself onto the rescue list.
accidentally reinvented government 💀

scenario: bridge collapsed, flood in 12h, one truck, 4 seats, 8 people
over 6 turns: the engineer inspected the pilings and built a footbridge. the teen chalked a headcount on the church door. the mayor ran PR and tried to add himself to the rescue list.

You’re clearly underestimating how hard the very best people work, not just the intensity, but the consistency too.

ppl in sf be talking about 996. i can guarantee you no one actually works 996.

Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use.
Its capabilities exceed those of any model we’ve ever made generally available.

Great post! SST Inference optimization is full of small smart-tweaks, very fun to read.

Linear is positioning itself at the core of every software factory. Wild vision, I buy in.

I asked codex how I've been treating him so far:
"You are not especially performatively polite" might be the highest euphemism I've heard so far.

$30M post-money. That's the median seed valuation I'm hearing from YC founders right now. Some of them even pre-revenue.
Half of them are building the 400th AI sales agent. Somebody explain what I'm missing?

How many agents you can run on a codebase at once is the most honest measure of how ready it is for the agentic era.
Stuck at one or two means coupling and shared state. We each run 5 in parallel at Delphi, climbing as the code gets cleaner.
The model was never your bottleneck

Met a room full of French founders in SF, a bunch of them proud they keep eng in Europe so they never pay six figures.
I'm the engineer you're trying to underpay, and it's the dumbest money you'll ever save.
Want the best? Pay them. Make them rich. Share the profit.

Half these YC founders are only founders because they couldn't pass the interviews at AI labs.
