Gemini 3.1 Pro leads ARC-AGI-2, LiveCodeBench, and 11 other benchmarks with 750 million users and 21.5% market share - but developers report stalled responses, leaked thinking tokens, and API outages that make it unusable for production coding and agent workflows.

Detailed comparison of Moonshot AI's Kimi K2.5 and Google DeepMind's Gemini 3.1 Pro - a trillion-parameter open MoE against Google's flagship multimodal model.

Four days after launch, Gemini 3.1 Pro's benchmark-topping performance is overshadowed by 90-hour lockouts for paying subscribers, quota draining while idle, and tool-calling bugs that break LangChain, n8n, and RooCode. Developers are switching to Claude.
