Replit Ghostwriter is an AI-powered pair programmer integrated into the Replit IDE, offering real-time code completion, generation, transformation, and explanation.
Replit Ghostwriter infuses state-of-the-art intelligence into the Replit IDE, acting as an ML-powered pair programmer. Its flagship feature, Complete Code, provides real-time code suggestions and completions, aiming to make coding faster and more accessible, especially on mobile devices. The tool also includes functionalities to generate, transform, and explain code snippets. Ghostwriter leverages optimized open-source Large Language Models (LLMs) like Salesforce's CodeGen, employing techniques such as FasterTransformer, Triton server, knowledge distillation, and quantization to achieve low-latency inference. It also features an in-editor semantic search utility, powered by finetuned CodeBERT models, allowing users to find and import open-source code using natural language queries, with contextual awareness based on the user's existing code. The development focuses heavily on user experience, addressing challenges like whitespace and brace matching, dynamic suggestion adjustment, and heuristic filtering to discard unhelpful suggestions. Streaming is implemented to present generated code as soon as possible, enhancing the perception of speed and integration into the programming workflow.
