|---|---|---|---|---|
| What it is | Verification infra you plug into your existing tool, or run standalone | All-in-one autonomous engineer — Devin Desktop (formerly Windsurf) unifies the local IDE and cloud Devin agent under one company | Bundled agent inside Copilot | Standalone issue→PR bot |
| Billing | Per verified and tested issue; failed attempts are free | Per-seat plus pay-as-you-go compute units | Per-seat AI credits, consumed regardless of outcome | Early-stage, small-scale |
| Verification before delivery | Independent oracle/QA verification ladder, including real test execution | Runs its own tests, no independent verification layer | Sandbox run, human review required | Runs tests/CI before opening the PR |
| Works with your existing tool | Yes — MCP mid-session | No — replaces your tool | Only inside the GitHub/Copilot ecosystem | No — separate bot |
For reference: a third-party SWE-bench Verified cost index (Morph LLM) put Claude Code (Opus 4.7, max) at $4.10 per resolved benchmark task and Codex (GPT-5.5, xhigh) at $4.82 — pure model-inference cost on a curated, single-language benchmark of 500 pre-vetted Python GitHub issues, each verified against that issue's own real pre-existing test suite (the same FAIL_TO_PASS/PASS_TO_PASS methodology Codemind's Cloud Repo Mode also uses). Codemind's own price is $0.10 per verified and tested issue in live production use, across arbitrary tenant code in multiple languages with no guarantee a clean fix or adequate test coverage exists going in.
Same verification method, different task population and cost basis — so take this as two real, sourced numbers side by side, not a multiplier.
Codemind isn't a replacement for your coding-tool subscription. It plugs into Cursor, Claude Code, or Codex over MCP and only adds cost when it actually verifies and tests a fix: $0.10 per verified issue, nothing for a failed attempt.
