Brave Leo and Claude Haiku join GeoGen's engines
GeoGen now tracks Brave Leo, the assistant built into the Brave browser, and Claude Haiku, both read the way users see their answers, at one credit a run.
Two engines joined the daily checks.
Brave Leo is the AI assistant built into the Brave browser on desktop, Android and iOS. Brave reports 128.3 million monthly active users of its browser (30 September 2026). For some questions Leo adds results from Brave Search, which runs on Brave’s own index rather than Google’s or Bing’s. See how Brave Leo answers.
Claude Haiku is Anthropic’s fastest Claude model. GeoGen reads its answers the way a user sees them, next to Claude Sonnet and Claude Opus, which it queries through the model API. See Claude tracking.
Both are read as users see them and cost one credit per run, so every plan can include them, Micro and Standard too. Compare the full list of AI engines and the credits per engine.
