About Benzi

Benzi provides benchmarks for AI-native code intelligence, comparing its performance against mainstream harnesses in bug-fixing, code understanding, and cost efficiency.

Benzi offers a comprehensive benchmarking platform focused on evaluating AI-native code intelligence. It measures performance across several key metrics, including source lines read, wall clock time, and cost per fix. The platform conducts 'apples to apples' comparisons against established harnesses and models like Claude Code and DeepSeek, using real-world GitHub issues across multiple programming languages.

One of Benzi's primary benchmarks is the bug-fixing benchmark, which involves solving 24 GitHub issues across 10 languages. It tracks the number of source lines read by each harness as bug difficulty increases, providing a clear KPI for code intelligence efficiency. Benzi also features a SWE-bench Verified benchmark, where its harness resolved 78.2% of 500 real issues at a cost under 10¢ per fix.

Beyond lines read, Benzi also benchmarks wall clock time and cost per fix, using published per-token rates for AI models. This allows for a detailed analysis of not just the effectiveness but also the economic efficiency of different code intelligence solutions. All benchmark runs, tasks, and attempts are made public and verbatim, ensuring transparency in its evaluations.

Pricing

free

The website does not mention any pricing for Benzi itself, suggesting it might be a free research or benchmarking tool. The pricing data presented on the site refers to the cost of AI models used in the benchmarks (e.g., DeepSeek, Sonnet).

Who is it for?

Best for

  • Evaluating the efficiency and cost-effectiveness of AI code intelligence models
  • Comparing different AI coding harnesses for bug-fixing capabilities
  • Understanding the performance characteristics of AI models in software development tasks
  • Research and development in AI-assisted programming

Not ideal for

  • Direct code generation or development (it's a benchmarking tool, not a coding assistant)
  • End-user software development without an interest in AI model performance
  • General-purpose project management or bug tracking

Integrations

GitHub (for issues)
