    How much detail would you like?

    Practical

    Relevant for productive enterprise applications where quality, speed and cost are simultaneously important.

    Example scenario: A team uses Claude Sonnet for coding and analysis tasks and routes only particularly difficult cases to Opus.

    Testing with representative corporate tasks against haiku, opus and alternative models; measuring quality, latency and overall costs together.

    At a glance

    Core
    Within the Claude family, Sonnet describes the balanced model class for demanding everyday, coding and agent tasks. It lies conceptually between the particularly fast haiku class and the performance-oriented opus class. Capabilities, context and prices are version-dependent.

    Limits
    Automatically treat Sonnet as the best choice for each task; mix version data; compare model class instead of real task evaluation.

    In context

    Questions about this term

    Is Sonnet a single permanent model?

    No, a model class with several versions.

    What is it suitable for?

    For balanced all-round, coding and agent tasks.

    All details and background

    Within the Claude family, Sonnet describes the balanced model class for demanding everyday, coding and agent tasks. It lies conceptually between the particularly fast haiku class and the performance-oriented opus class. Capabilities, context and prices are version-dependent.

    ELI5 – Explained simply

    Sonnet is the balanced Claude variant: powerful for many complex tasks without always using the most expensive model class.

    Why it matters in practice

    Relevant for productive enterprise applications where quality, speed and cost are simultaneously important.

    Example

    Example scenario: A team uses Claude Sonnet for coding and analysis tasks and routes only particularly difficult cases to Opus.

    Pitfalls and limits

    • Automatically treat Sonnet as the best choice for each task; mix version data; compare model class instead of real task evaluation.

    Origin & history

    Anthropic introduced Sonnet in 2024 as part of the Claude 3 family and continued to develop the model class over generations.

    Use in mid-sized companies

    • Testing with representative corporate tasks against haiku, opus and alternative models; measuring quality, latency and overall costs together.
