The lifecycle of a code AI completion (via) Philipp Spiess provides a deep dive into how Sourcegraph's Cody code completion assistant works. Lots of fascinating details in here:

"One interesting learning was that if a user is willing to wait longer for a multi-line request, it usually is worth it to increase latency slightly in favor of quality. For our production setup this means we use a more complex language model for multi-line completions than we do for single-line completions."

This article is from October 2023 and talks about Claude Instant. The code for Cody is open source so I checked to see if they have switched to Haiku yet and found a commit from March 25th that adds Haiku as an A/B test.
