GPT-5.5
OpenAI1. Strongest Agentic Coding Model
- State-of-the-art on Terminal-Bench 2.0 (82.7%), Expert-SWE (73.1%), and SWE-Bench Pro (58.6%), outperforming GPT-5.4 on complex coding tasks.
- Holds context across large systems, reasons through ambiguous failures, and carries changes through surrounding codebases with fewer tokens.
2. Higher Intelligence at GPT-5.4 Latency
- Co-designed, trained, and served on NVIDIA GB200/GB300 NVL72 systems to match GPT-5.4 per-token latency while performing at a significantly higher level.
- Uses fewer tokens to complete the same tasks, making it more efficient as well as more capable.
3. Powerful for Knowledge Work & Computer Use
- Scores 84.9% on GDPval (44 occupations) and 78.7% on OSWorld-Verified for autonomous computer operation.
- Excels at generating documents, spreadsheets, and reports; naturally moves across finding information, using tools, and checking output.
4. Scientific Research Co-Scientist
- Leading performance on GeneBench, BixBench, and FrontierMath; helped discover a new proof about Ramsey numbers verified in Lean.
- Strong enough to meaningfully accelerate progress at the frontiers of biomedical and mathematical research.
DeepSeek R1
DeepSeek1. Real-time reasoning and decision-making
- Built for scenarios that require instant output.
- Great for applications with fast-changing data.
2. Excellent for dynamic optimization
- Pricing adjustments, recommendations, routing, and system tuning.
3. Strong performance in finance and e-commerce
- Tracks market shifts.
- Updates predictions on the fly.
- Optimizes recommendations in real time.
4. High-speed pattern recognition
- Quickly interprets signals from streaming data.
- Useful in trading bots, alerts, and monitoring systems.
