Built by Cursor. Built on Buildkite. (Sponsor)

Devs finally have a challenger to GitHub code hosting with Origin.

Origin was built on Buildkite.

Buildkite is a launch partner for this new code ecosystem. Origin holds the code. Buildkite runs the build. Vercel ships it. Three layers, one path from idea to production.

We also run CI for OpenAI, Anthropic, Mistral, xAI, Airbnb, Nvidia, Canva, Uber, Meta, Pierre, Bun and more.

Build faster, more securely, more reliably, with the CI engineered for frontier scale, used by the frontier labs setting the pace.

Clinic-in-the-Loop (16 minute read)

Faster testing in the clinic creates a feedback loop. Ideas become trials that generate rich data, which improves data models, and better models inform the next generation of ideas. The clinic is a central component of discovery. Even data from failed trials can be useful. Optimizing trial efficiency is about learning fast enough to make success more likely.
