How do you build reliable AI tools at scale? @withgraphite 's solution: systemic evaluation. See how Graphite said goodbye to ad-hoc manual testing and leverages Braintrust to ship features like their AI code reviewer, Diamond: https://t.co/PZdclOGgNZ

The office this morning as we prepped to launch Graphite Chat. Nothing beats the feeling of shipping with the team after months of hard work!

Spoke at @Ai4Conferences about something we see daily at Graphite: writing code isn’t the bottleneck - review is. AI accelerates the inner loop; the outer loop now needs superpowers

Snowflake now uses Graphite for high quality AI reviews. Over 60% of bugs caught lead to real fixes before they hit prod. Less time fixing. More time building.
