i've been to 132 conferences in 11 countries. this is the best talk I've ever seen in my life. a coffin on stage projection mapping auto-advancing hands-free slides and fascinating storytelling @davekiss's talk had it all.

Meet AutoRouter, the most intelligent way to pick models You’re wasting tokens selecting frontier models for every prompt, and sometimes for worse performance AutoRouter handles the decision layer: - Understands the prompt request - Picks the best model fit for the task - Saves you money at every turn - Plugs into your current setup Works with your plans & every leading model inside Codex/Claude Code Beta is live: autorouter.com

today we’re releasing AutoRouter for public alpha run opus 5.5 or any other open source models inside codex or auto route by complexity to save big on frontier subscriptions it attaches to codex & adds new models directly in the app’s picker so you’re not switching harnesses once your subscription runs out rolling people off the waitlist today & tomorrow → autorouter.com

Been testing @inflight for a little while, and if you're a designer who shares prototypes for feedback, this one's for you. Excited it's finally out! 🖤
introducing @inflight the missing feedback layer for prototypes ⇢ works with any agent ⇢ supports pinned comments + video ⇢ turns feedback into next steps for Claude

Made a post on reddit about how the wealthsimple desktop app feels very professional now, as a software eng, I can appreciate this craftsmanship, the app performance esp for android is so much better. big ups @brotzky @tcosta @tjruss reddit.com/r/Wealthsimple/co…

Software is increasingly treated as disposable in the AI era. Yet we spend half our waking lives looking at screens! We don’t want to spend that time with zombie products—monotonous, vacant, and uncared for. We want products with soul. 💜 I go deep on this in my talk from @lennysan's Summit: youtube.com/watch?v=GLvFTMtw…

We have a new AI teammate named Compass. It lives in Slack and is becoming a fast friend. Read more about what it does and how we built it in our latest engineering blog. engineering.wealthsimple.com…

Slow works. A philosophy that I resonate with completely.

Current snapshot: - Human attention is the blocker - Models feel smart enough but too slow - Astra/Fable don't produce 'bugs' - Code review losing value - Spec, guidance, direction feel important - Traditional CI/PR/Tests feel very dated - Taste increasing in value
Things are definitely changing. Current snapshot: - Write 0% of code by hand - Haven't opened an IDE - PRs automated with ai - Stopped opening linear - Stopped copying figma css In general at work I get 'annoyed' when I have to open an app because ai cant complete the flow.

Few understand this is actually how you use AI, on the creation side. It's exactly where deterministic soltuions like LLMs shine when paired with workers that know what they re doing.
Replying to @tcosta
For this poof, I made 2 frames by hand. AI made the 4 in between. Six cells, 340ms, one sprite sheet. Hand-made where it matters. Generated where nobody notices.

this weekend’s tinker project... Sombra started as me messing around recreating Dia’s gradient effect and wanting to make my own variations for a side project still pretty rough / very much a wip, but a lot of fun to play with. export whatever you make as code or svg too.

update on the table of contents component. kept the blur, the staggered reveal, and the collapse on hover out from the original, just tightened all three until they felt inevitable instead of decorative. inspo @brotzky @tcosta @tjruss, the Fey team set the bar here.
