Key point
Replit has unveiled **Ghostwriter** and the **Complete Code** beta, AI coding tools with real-time code completion.
Details
Replit announced Ghostwriter, which brings intelligence to every feature of the IDE. Ghostwriter provides real-time code completion, code generation and explanation tools, and the ability to search open source code without leaving the editor.
Its core feature, Complete Code, is an AI-powered pair programmer currently running in closed beta. Users rate it as 2-3 times faster than GitHub Copilot, dramatically speeding up web development and learning.

Key optimization strategies include:
- Inference optimization using FasterTransformer and Triton server
- Compressing the 2B model into a lightweight 1B-scale model via Knowledge Distillation
