Major upgrade to Gemini 3 Deep Think reasoning mode
Strengths
- ・Undisputed leader on abstract reasoning (ARC-AGI-2 84.6%) and competitive programming (Codeforces 3455)
- ・Gold-medal performance on IMO, IPhO (87.7%), and IChO (82.8%) 2025
- ・Strongest scientific reasoning across chemistry, physics, and condensed matter theory
- ・Multimodal input support (text, images, audio, video)
- ・1M token context window
Weaknesses
- ・Trails Claude Opus 4.6 on agentic enterprise tasks (GDPval-AA ~1200 vs 1606)
- ・Weaker on practical coding (SWE-bench 76.2% vs Claude 80.8%)
- ・Higher latency due to deep reasoning chains
- ・Higher cost than Gemini 2.5 Deep Think ($2/$12 vs $1.25/$10)
- ・Early API access only (not broadly available as of Feb 2026)
Competitor Comparison
| Model | Arena | SWE | GPQA | Price |
|---|---|---|---|---|
| Gemini 3 Deep Think | ~1500 (est) | 76.2% | 93.8% | $2/$12 per 1M |
| Claude Opus 4.6 Thinking Max | ~1490 | 80.8% | 91.3% | $15/$75 per 1M |
| GPT-5.2 Thinking xhigh | ~1480 | 80.0% | 93.2% | $5/$20 per 1M |
| Gemini 3 Pro (standard) | ~1470 | 76.2% | 91.9% | $2/$12 per 1M |
The February 2026 upgrade to Gemini 3 Deep Think is Google's most powerful reasoning mode, achieving state-of-the-art results on ARC-AGI-2 (84.6%), Codeforces (3455 Elo), and multiple international science olympiads. It excels at abstract reasoning, mathematical proofs, and scientific analysis but trails behind Claude Opus 4.6 on practical agentic and enterprise tasks.
