Gemini 3.1 Pro (Feb 2026) is Google's frontier model — top-tier reasoning, native multimodality (text/image/audio/video) and a 1M-token context, with India-friendly INR billing.
Best for
- Frontier science and math (GPQA ~94, AIME ~100)
- Long documents, video and large codebases (1M context)
- Search-grounded, up-to-date answers
- Hindi and Indian languages via Google's ecosystem
How it compares — and the India angle
- Leads/ties Claude Opus on science (GPQA) but trails it on SWE-bench coding.
- Unique India edge: Google AI Pro is ~₹1,950/mo with native UPI/Google Pay — far easier to buy than Claude (no INR billing).
- Drop to a Flash tier when speed or cost beats peak reasoning.
