Google ranks the best AI for building Android apps, and the winner isn’t Gemini

Google's Android Bench leaderboard, launched in March and recently updated, ranks AI models on their ability to generate code for Android development tasks. As of the May 18 update, OpenAI's GPT 5.5 tops the leaderboard, beating Google's own Gemini. The benchmark uses real-world issues and pull requests from public GitHub Android repositories to evaluate LLMs on tasks like resolving breaking changes across Android releases, domain-specific networking, and Jetpack Compose migrations. The leaderboard now also includes open-weight models and metrics for latency, token usage, and cost. Industry observers praise the domain-specific approach but warn about data contamination risks, noting that models trained on public repos may score artificially high on public benchmarks while performing differently on private evaluations.
