I’ve been experimenting with next-edit prediction for a while and wrote up how we trained the edit model that powers our Tab completion feature. This post is part of a broader series where we share how we built this feature from the low-level modeling right up to the editor extension.

The cool part is we fine-tuned Gemini Flash Lite with LoRA instead of an OSS model, helping us avoid all the infra overhead and giving us faster responses with lower compute cost.
