The latest Android coding leaderboard, a benchmark that evaluates how well different AI models can perform Android development tasks, introduced Gemini 3.5 Flash for the first time, but the newcomer didn’t make it into the top five. Topping the list was OpenAI’s GPT 5.5, which scored 74, followed by GPT 5.4 and an older Google model, Gemini 3.1 Pro Preview, both with 72.4.

At Google I/O 2026, the company announced the most powerful Flash model it had ever built, Gemini 3.5 Flash, which it claimed had more robust coding capabilities and better support for AI agents and complex workflows. Google also said the model outperformed Gemini 3.1 Pro in a number of internal benchmarks and produced output up to four times faster than competing frontier models.
