How good is Claude Sonnet 4.5 at product design? I put it to the test against opus 4.1 and gpt-5 on 3 tasks with different difficulty levels. Honestly, didn't expect this result at all.

Ruby from Ruby, the AI designer is the digital employee for product design. Ruby will improve your product while you sleep - just add her to Slack. - Run design experiments on your flows - Create new screens to unblock engineers - Do cumbersome design research ion.design

We're live through YC! Ruby's gone through a journey and is adding tons of value to teams of many sizes you can add her and get started today :)

.Relace has raised $23M to build the rails for AI code generation. This round is led by a16z, with participation from Matrix and Y Combinator. LLMs have proven they can write code—but scaling that code into production still needs better infrastructure. Relace is

Cursor’s Plan mode is whats been missing from my life

Over 90% of YC companies end up failing So I built an app to predict if they will become a unicorn or not. Try it out, link below.

Whatsup with san francisco and not mixing burritos?? Why must we eat half sour cream and lettuce and half chicken and cheese

cool benefit of vibe coding is that you can make really sick interactive elements in blog posts like this

LLMs aren’t as smart as you think. We send them billions of prompts every day, and they have no idea what we’re actually saying. I wrote a blog explaining how this works, with fully interactive visualizations.

claude 4.5 is cool and all but why are you guys lying so much jesus christ, the current discourse right now is making twitter unusable

Today, Listen crossed $100M in funding. Building is easy now. Knowing what to build isn't. Our AI finds and talks to your users so you don't have to guess. See how Sweetgreen, Microsoft, and Replit use it:

Something big is coming to Claude

At Listen we don't accept anything but the best. Linear did not have the capabilities we wanted, so we had to build Req Rubin. Req handles tickets for us now. New customer request? Req will add and consolidate. CS is wondering if their request is being worked on? Req knows
