Building high-quality apps with LLMs demands AI that truly understands the Android ecosystem. That’s why we’ve introduced Android Bench, the official leaderboard for LLMs in Android development 🏆.

We’ve tested models against real-world tasks – from Jetpack Compose migrations to complex logic fixes – to help model creators identify gaps and accelerate improvements.

Explore the leaderboard and review our methodology: https://t.co/aVNMYbXQIl
