Key Features
  • • Frontier-model agent grounded in Sourcegraph's code graph
  • • Monorepo-scale code intelligence: references, call sites, dependencies
  • • Shared threads between VS Code and CLI

    Sourcegraph Amp - Pros & Cons

    Pros

    • ✓Monorepo code-graph grounding beats embedding-only competitors on large repos.
    • ✓Pass-through token pricing rewards heavy use instead of capping it.
    • ✓Shared threads across VS Code and CLI match how senior engineers actually work.

    Cons

    • ✗No managed model — you bring API keys, which is friction for team buyers.
    • ✗VS Code extension is newer and less polished than the established Cody extension.
    • ✗CLI is powerful but documentation still lags the product roadmap.

    Cosine Genie - Pros & Cons

    Pros

    • ✓Genuine async workflow — file a ticket, get a PR, review in your normal flow
    • ✓On-prem option clears regulated-environment procurement
    • ✓Lumen models tuned for engineering tasks, not generic chat
    • ✓Slack/issue-tracker triggers make integration with existing workflows easy
    • ✓Strong SWE-bench Verified credibility from launch onward

    Cons

    • ✗Team-tier pricing is steep relative to in-editor copilots
    • ✗Like all autonomous agents, quality drops on ambiguous tickets or messy codebases
    • ✗Younger / smaller vendor than GitHub or Cursor — vendor risk for the cautious
    • ✗Sandboxed-cloud per-task model can make latency unpredictable
    • ✗Best gains require teams to invest in clearer ticket hygiene
