Modes & Models

Amp uses the best model for each task: leading generalist foundation models for complex reasoning and planning, and smaller specialized models for fast, accurate responses in specific domains.

Agent Mode Plugins

Plugins extend Amp with new tools, commands, and agent modes. These experimental modes are how we evaluate new models, and we're sharing them so you can, too. Fork and modify the plugins to run your own experiments.
