GitHub Copilot

GitHub CopilotSince 2021-10

An AI-powered developer tool that provides autocomplete-style suggestions as you code. It learns from your project context to generate relevant functions and snippets.

Built by GitHub using OpenAI's large language models specifically trained on public code repositories.

SupermavenSince 2024-02

Supermaven is an ultra-low-latency AI code completion extension engineered by the creators of TabNine. Renowned for its industry-leading response speed and massive 300,000-token context window, Supermaven delivers sub-100ms inline suggestions that feel instant compared to traditional LLM copilot extensions. By ingesting your entire repository into its specialized Babble neural architecture, Supermaven understands project-wide type definitions, custom internal libraries, coding conventions, and recent file edits with unprecedented accuracy. Available across Visual Studio Code, JetBrains IDEs, and Neovim, Supermaven offers a generous free tier for individual developers alongside a high-context Pro tier for professional engineers.

Supermaven's competitive edge stems from its proprietary Babble model architecture, which is specifically trained for low-latency next-token code synthesis rather than heavy generalized conversation. This design enables Supermaven to stream full multi-line code completions in under 50 milliseconds. The 300,000-token context window allows the model to maintain the entire working state of medium-to-large codebases in memory simultaneously. When you refactor a data model or add a new API route, Supermaven immediately adapts its completions across all related controllers, frontend components, and test files. Supermaven also enforces enterprise-grade security protocols, ensuring that proprietary source code is never stored or used for foundational model training.
