Amp is a coding agent from Sourcegraph available as a CLI (@sourcegraph/amp on npm) and editor extension. The agent uses multi-model routing across Claude Opus, GPT-5, and fast models with three explicit task modes: smart (default), rush (fast/cheap), and deep (extended thinking). Amp selects the model per task without manual configuration.
The Sourcegraph Librarian is the codebase context layer. When connected to GitHub, it indexes private repositories and makes them searchable by the agent, giving it visibility beyond the current working directory. Every interaction is saved as a thread that can be shared with teammates and cost-tracked via amp usage.
Pricing is pure pass-through: users pay actual LLM API costs with no markup above a $5 minimum credit purchase. There is no per-seat subscription. Enterprise workspaces add SSO, Zero Data Retention for LLM inputs, MCP registry allowlists, IP allowlisting, and per-user cost controls. Amp runs on Google Cloud multi-tenant infrastructure; no self-hosted option exists.
