Strengths
- Frontier agentic and coding performance at Flash-tier cost — ARC-AGI-2 72.1% (close to Gemini 3.1 Pro 77.1%)
- State-of-the-art multimodal understanding (MMMU-Pro 83.6%) across text, image, video, audio and PDF inputs
- Strong tool-use and computer-use workflows (Terminal-bench 2.1 76.2%, OSWorld-Verified 78.4%)
- 1M token context window with 64K tokens of output capacity
Limitations
- Preview model — behavior may change
- DeepMind reports agentic and reasoning benchmarks but not classic academic suites (MMLU, MATH-500, HumanEval, IFEval)
- Higher completion price than Gemini 3 Flash ($9/M vs lower previous Flash tiers)
