Escenarios de corrección de bugs
Cada ejecución comienza con un test fallido reproducible y termina con verificación.
Measured across 87 bug-fix tasks on identical checkouts: Codna verified 87/87 (100%) at ~$0.02 per fix — 5× fewer tokens and 1.7× faster than Cursor, and 6.6× cheaper than Cline (which verified only 73.6%).

Metodología
El conjunto de benchmarks incluye bugs individuales, múltiples bugs en un repositorio y repositorios no vistos por el agente. Cada escenario se cuenta solo cuando el test pasa.
Cada ejecución comienza con un test fallido reproducible y termina con verificación.
Codna comprendió 130 repositorios en 110 lenguajes en 9,2 segundos.
Codna envía al agente un paquete de evidencia en lugar de todo el repo.
Measured spend to ship one verified fix — about 28× cheaper than a typical agentic edit.

Codna ran head-to-head against OpenAI Codex CLI and Google Gemini CLI across 8 real bug-fix scenarios. Every fix was verified by the project's own tests. No synthetic tasks, no self-reported numbers.
A fix counts only when the test suite passes. Codna went 8 for 8. A fix that compiles but breaks tests is not counted.
Codna sends the AI agent an evidence bundle measured at roughly 600 tokens — 162x less context than reading the full repository. That translates directly to lower API costs, typically pennies per fix.
The deterministic engine maps the dependency and blast-radius graph in about 60 ms using zero LLM tokens. The agent receives only the relevant evidence, so there is far less to process before a fix is produced.
Yes. In measured testing, Codna mapped 130 repositories in 9.2 seconds, using zero tokens for the mapping step.
The benchmark compared Codna against the default configurations of OpenAI Codex CLI and Google Gemini CLI as available at time of testing. Codna is bring-your-own-key, so you choose the underlying model.
