Technical deep dive: ARC-AGI-2 benchmark performance
The Adaptive Reasoning Capacity (ARC-AGI-2) test suite evaluates AI systems across 200+ tasks requiring pattern recognition, algorithmic thinking, and spatial reasoning. Gemini 3.1 Pro’s 77.1% accuracy—up from 38.4% in Gemini 2.0—marks a significant leap in generalization capabilities. Notable achievements include:
| Task Category | Gemini 3.1 Pro | Gemini 2.0 | Human Baseline |
|---|---|---|---|
| Algorithmic Pattern Recognition | 89.2% | 41.5% | 92.0% |
| Multi-Step Mathematical Reasoning | 83.7% | 35.1% | 88.5% |
| Visual-Spatial Logic | 71.4% | 40.3% | 75.0% |
This performance closes the gap with human-level reasoning while maintaining enterprise-grade reliability for production systems.
