Amp

Amp is Sourcegraph's coding agent, built on an explicit bet: model capability improves fast, so the agent should always use the best available model rather than a cheaper one tuned for margin. There are no model pickers and no token-saving compromises.

Characteristics

• Terminal-first, editor-friendly. A CLI for interactive and scripted use, plus VS Code and JetBrains extensions.
• Subagents. Amp spawns focused subagents for parallel work — searching, editing, verifying — which keeps the main thread's context clean on long tasks.
• Real execution. It runs commands, reads output, iterates on failures, and can drive a browser to check its work.
• Shareable threads. Sessions are URLs, so a teammate can read exactly how something was built or debugged.
• Team features. Shared threads, usage visibility, and leaderboards for teams adopting agentic workflows together.

Pricing model

Usage-based rather than per-seat: you pay for the tokens consumed, with free credits to start and a free tier option. That aligns cost with actual work and avoids paying for idle seats, though heavy use is genuinely metered.
