    How much detail would you like?

    Practical

    Helps with a first model selection, but does not replace a check on your own code.

    Example scenario: A team compares benchmark results and then tests two models with their own maintenance tasks.

    Use as a comparison point for programming assistance and compare it with your own requirements, data protection and tests.

    At a glance

    Core
    The Aider benchmark evaluates models based on programming tasks in the Aider test setup. The Polyglot Benchmark contains 225 tasks in six programming languages. It must be distinguished from the older Python benchmark; results apply to the respective version and test configuration.

    Does the test measure every programming ability?

    No, only the tasks in the respective construction.

    Are values of different versions directly comparable?

    Only under comparable conditions.

    All details and background

    The Aider benchmark evaluates models based on programming tasks in the Aider test setup. The Polyglot Benchmark contains 225 tasks in six programming languages. It must be distinguished from the older Python benchmark; results apply to the respective version and test configuration.

    ELI5 – Explained simply

    Several models solve the same code tasks under specified conditions. The solutions are then tested.

    Why it matters in practice

    Helps with a first model selection, but does not replace a check on your own code.

    Example

    Example scenario: A team compares benchmark results and then tests two models with their own maintenance tasks.

    Pitfalls and limits

    • Mixing benchmark versions; reading rankings as a general quality guarantee; ignoring cost and editing format.

    Origin & history

    Aider introduced the more sophisticated polyglot benchmark in December 2024. He extends the test to several languages.

    Use in mid-sized companies

    • Use as a comparison point for programming assistance and compare it with your own requirements, data protection and tests.
