Methodology

The AI panel is a versioned set of providers, models, web-search tools, prompts, languages and regions, run on a fixed cadence with repeats. When a provider changes a model or search behaviour, we create a new panel version rather than splicing incompatible series.

Discovery tests never insert the target URL into the model context — doing so would contaminate the measurement. Metrics report eligible-run denominators with visible sample sizes. Full panel configuration and changelog render here.
