✨ Introducing Genie, an AI software engineering model

About Us

Cosine is a Human Reasoning Lab. What this means is that we’re researching how to codify exactly how a human would perform tasks, then teaching AI to mimic, excel at and expand on the same jobs. This is the opposite of throwing spaghetti at the wall.

Genie is an application of our above philosophy. Genie is a fully autonomous Software Engineering colleague that has achieved the highest eval score in the world on SWE-Bench.

We’re curious, candid, and maximalist all the time

Our vision is to codify human reasoning and apply it to hard problems. The first such problem is software engineering. Cosine started because 3 friends were curious to see how far we could push Davinci-2, each iteration we were candid about the knowns and unknowns, but we remained maximally enthusiastic, optimistic and curious about what comes next. Finally the tech has matured enough for us to ship our vision.

Small but mighty

We’re only a team of five, between us we’ve scaled and exited multiple unicorns, managed huge global teams, and have even been coding since the early age of eight. We remain laser focused on our goals and work very closely and collaboratively on hard problems. We hire selectively like all great startups but in particular we look for obsession (about anything, even a hobby!), optimism and antifragile traits.
