About

Amp is the agentic coding tool that Sourcegraph spun out in December 2025 as an independent company founded by original Sourcegraph co-founders Quinn Slack and Beyang Liu — the same product path that absorbed the agentic ambitions of the now enterprise-only Cody. It runs from a CLI and integrates with VS Code, JetBrains, Neovim and Zed. The agent structure is unusually model-mixed: smart mode runs Claude Opus 4.7, deep pairs GPT-5.5 with extended thinking, rush runs GPT-5.5 without reasoning for cheap small tasks, and an Oracle tool gives the main agent an on-demand second opinion. Subagents handle search, library lookup and review on their own models. Threads are the unit of work and can be shared by URL and resumed later. A May 2026 rewrite of the CLI (shipped as Neo, GA later that month) added auto-compaction at 90% context, a TypeScript plugin API and remote thread control from ampcode.com — but also removed file rollback, user-invocable skills and, importantly, default permission prompts, so tools now run without approval unless you configure otherwise. Billing is the differentiator: there are no subscription tiers. You pay provider rates with zero markup, with a $5 minimum purchase. Amp Free was $10/day of credits (about $300/month) but stopped accepting new signups on 2026-02-10, and unused credits expire after a year of account inactivity. Execute mode and programmatic calls consume paid credits only. Enterprise is the same pass-through pricing plus a 50% markup and a $1,000 one-time onboarding fee, adding SSO, SCIM, zero data retention and an MCP allowlist. The catch: Amp publishes no per-token rates, so cost control depends on watching thread costs after the fact.

Deals, Discounts & How to Save

Zero-markup pass-through billing — you pay the model provider's list price, nothing on topRush mode for small tasks: roughly $0.58 per task versus frontier pricingCredits never expire monthly — leftovers only lapse after a year of account inactivity

Amp does not charge a markup, so your bill is whatever the models cost — which means the leverage is in model choice, not discounts. Route routine edits to rush mode, keep deep and smart for work that genuinely needs frontier reasoning, and remember that any free or promotional credits are separate from execute-mode usage, which always draws on paid credit.
