Introducing Lemma. Your AI agents are failing in ways you can’t see. Lemma is the world’s first reliability platform that finds and fixes these issues fast.

More of this please Actually if you believe computer aided design and engineering is about to become 100x more awesome thanks to AI, it might just happen now

Today, we're announcing Traverse. @traverseso We're building reinforcement learning environments for long-horizon agent journeys, and our goal is to automate all economically valuable work. The data labeling industry is broken in ways that aren't obvious from the outside. Semi-experts annotate, non-experts QA, non-technicals manage the entire pipeline, and post-training on your own data still isn't standard. The feedback loop is fundamentally broken, and bad data is being delivered to AI labs. We envision the opposite, pairing world-class domain experts with world-class ML engineers at every layer of our stack. Our bar is extremely high because mediocre environments pollute the frontier models, and we'd rather not add to that. Traverse will start by automating software engineering, as agents that write code can improve the infrastructure we use to train them, and we want that flywheel running as early as possible. Everything else follows from there. If you're a researcher or frontier lab thinking about long-horizon agents, reach out. traverse.so

hillclimb (@hillclimbai) is the human superintelligence community, dedicated to building golden datasets for AGI. Starting with math, their team of IMO medalists, lean experts, PhDs is designing RL environments for @NousResearch.

Inspector (@tryinspector) is an AI IDE for front-end that connects browser and codebase. It lets you select elements visually and prompt changes, giving coding agents access to the same runtime context developers have: visuals, elements, and logs.

@juecd__ @onkernel how do we cop one👀

kernel.browsers.create()

Pretended to be a college student for a weekend @UMich

@GaddipatiHarsha 9-12-6 so now I get a day off🙏

@imbobwei What happened to 9-9-7

First day off in a few months🍻

@guo_dini Yo how did u get a pic of my room😭

"we've been grinding every since we got into YC. you should come by our office sometime!"

Video Gen is getting REALLY good and more consistent. What if VIDEO was the computing primitive? (h/t @GeminiApp) Here is what an app might look like:

embedder, factory, cognition, and cursor on the same panel :)

@sweatbuilder Peak male performance right here

Yo opus 4 please make me 5 figures MRR

@glenntoews married to the company

@imbobwei Bob Embedder

Notable founder now apparently

@anantg4rg lock in

i have found the one. i will stop at nothing

How I feel
