Anthropic uses 1000 engineers to make Claude Code better

Anthropic is working with Snorkel AI on a project called 'Marlin' to improve its AI coding tool Claude Code. They hired about 1,000 human software engineers for this.

Workers compare code from two different models, pick the better one, and check if it matches the instructions. Each task pays $280 and takes about an hour.

The goal is to make Claude Code's answers more like real developer work, producing simpler and easier-to-maintain code. The project is still ongoing, and workers don't know which model version they're testing.
