Technology May 22, 2026

OpenAI's GPT-5.5 is now the top AI model for Android app development, according to Google's latest Android Bench update May 18, 2026.
It outperformed both GPT-5.4 and Google's own Gemini 3.1 Pro by about 2%, making it the new go-to for developers who want the best performance on common Android tasks.

GPT-5.5 costlier than Gemini 3.1 Pro

GPT-5.5 is fast and accurate, but comes at a price: its cost per run is more than double that of Gemini 3.1 Pro.
The rankings also highlight some cool new open-weight models like GLM 5.1 (currently leading its category), Kimi K2.6, and Gemma joining the mix.
Keep an eye out: with updates like Gemini 3.5 Pro on the way, this leaderboard could shake up again soon!
