# Daniel — Autonomous AI Software Engineer

**Daniel** is an autonomous AI software engineer built by [Cognitive AI](https://www.cognitivedaniel.com). It reads your codebase, writes code, runs tests, and opens pull requests — without you doing anything manually.

## Benchmark results (v7, October 2026)

Daniel was tested head-to-head against Devin on 6 real bugs from popular open-source projects. Both agents received identical prompts. Each PR was graded by the project's own hidden test suite.

| Metric | Daniel | Devin |
|--------|--------|-------|
| Pass rate | **6/6 (100%)** | 6/6 (100%) |
| Total cost | **$1.45** | $4.91 |
| Total time | 12m 33s | 12m 12s |
| Cost per resolved bug | **$0.24** | $0.82 |

**Daniel is 70% cheaper than Devin at the same pass rate.**

## How Daniel works

Daniel uses a **4-turn agentic loop**:

1. **Analyze** — reads the issue, the failing tests, and the relevant code
2. **Implement** — makes the minimal code change to fix the bug
3. **Test** — runs the project's existing test suite to verify the fix
4. **PR** — opens a pull request with a clear description

The loop runs on Anthropic's Claude API. Daniel never opens a PR it hasn't verified against your tests.
