Amp

Amp is a frontier coding agent built by Sourcegraph that brings AI assistance directly into your development workflow. Unlike simple code completion tools, Amp is designed as a true agent that can understand your entire codebase, execute commands, edit files, and work autonomously on complex tasks.

It features unconstrained token usage and automatically routes tasks to the best available models, including Claude Opus 4.5, GPT-5.2, and o3-mini. Amp operates seamlessly as both a CLI tool and an IDE extension, enabling developers to refactor code, fix bugs, and implement features with high autonomy.
