Announcement: I'll be joining @DecagonAI tomorrow in San Francisco as an intern on the AI Infra team working on AI DevX! At Decagon, I'll try to answer the question: "how can we build systems that improve the experience, productivity, and quality of AI use across a company?" If you're in around in SF, I'd love to chat. Excited to work and see all of you soon!

Top 50 most talent-dense breeding grounds for founders. Palantir at #1, Stanford at #2 and surprisingly Yahoo at #3.

instead of getting ai psychosis from your agents, you should give your agents your personal psychosis instead

Game design explains the shift in how agents should work better than most AI takes right now. We’re moving past heavy steering. The parallels are clearer than people realize.

Devin can do more than ship PRs. @DecagonAI used it to run an inference research lab. One Devin orchestrates, subagents chase competing hypotheses in parallel, and every idea is tested against replayed production traffic on @modal GPUs. The result was up to 2.5× more throughput per GPU.

I think many of us working in tech tend to forget that the reason software engineering vs other engineering fields pays (a lot!) more, is a lot more flexible (WFH/remote), and has better perks: Because this field changes much faster than other engineering fields. The premium is because fewer people are able/willing to pick up new technologies, methodologies so quickly. But the field had ~10-20 years of stability, and so lots of folks forgot this is why a premium exists. And that AI is just another tech wave: software engineers who pick it up and master it will generally fare better; those not will struggle a lot more.

If you’re a founder or engineer tired of user bug reports and issues flooding your software feed, try @Simulithic and give these guys a quick call!

Shipping code shouldn’t mean hours of manual testing. @Simulithic (YC F26) sends AI agents through your app like real users, across browsers, devices, and account types. It tells you what broke without you writing a single test script. The teams that ship fastest will be the ones that can verify as fast as they build. Get started today: simulithic.com

I reverse engineered Pocket and made it 10X better. Right now: the app is full of ads, the microphone is low quality, it constantly misspells peoples names, and has no agentic features. I changed that.

AI is downstream of Cloud Cloud is downstream of Hardware Hardware is downstream from Chips Chips are downstream of Rare Earths Therefore, Anthropic is a Rare Earth mining company

We all consider Anthropic an AI company. But what if it's a cloud?

Doing a hackathon with @eduardfausgil & @ayushrgarg was the best decision I’ve ever made I was in India, about to give up on tech back in 2022, met these 2, learned how to build cool things with them, and it changed my life (Picture below is approximately 4.5 years apart lol)
