The model demonstrates particularly exceptional performance on mathematical reasoning benchmarks — 98.3% AIME 2026 represents near-perfect performance on competition-level mathematics. The 98.0% ARC-AGI score is also notable — this benchmark was designed to test abstract reasoning that AI models should find difficult. Gemini 3.1 Pro achieves near-ceiling performance on ARC-AGI, alongside 94.3% GPQA Diamond (graduate-level physics, biology, chemistry). The 85.9% BrowseComp score (vs Gemini 2.5 Pro's strong showing on web research) suggests Gemini 3.1 Pro maintains Google's lead on web-grounded research tasks. ## Specifications | Field | Value | |---|---| | Organization | Google | | License | Proprietary (API only) | | Release date | March 2026 | | Knowledge cutoff | January 2026 | | Modality | Multimodal | ## Pricing Available via Google AI Studio and Vertex AI.
