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.
Sora 2
OpenAI1. Advanced Video Generation Capability
- Produces richly detailed, cinematic video clips from simple text or image prompts.
- Handles complex scenes, motion, lighting, environments, and multi-object interactions with high fidelity.
2. Synced Audio Generation
- Generates audio that aligns with the timing, actions, and mood of the video.
- Useful for creating complete media outputs without requiring external sound design.
3. Multi-Modal Input, Multi-Media Output
- Accepts text and image inputs, enabling:
- Storyboard-to-video workflows
- Image-to-video transformations
- Concept illustrations expanded into full scenes
- Outputs video and audio, making it ideal for end-to-end content creation.
4. Resolution-Optimized Performance
- Provides high-quality generation at:
- Portrait: 720 x 1280
- Landscape: 1280 x 720
- Optimized for common mobile and web video formats used in social media, ads, and creative production.
5. Powerful Media Understanding
- Interprets natural language with strong scene comprehension.
- Capable of rendering realistic movement, physics, emotions, and atmosphere.
- Suitable for:
- Marketing videos
- Short films and creative storytelling
- Product demos and conceptual visualizations
6. Integrated Across Major API Endpoints
- Supported in Chat Completions, Responses, Realtime, Assistants, and Videos endpoints.
- Makes it easy to integrate into agent workflows or interactive production pipelines.
7. Consistent Model Behavior via Snapshots
- Offers stable snapshots to lock model performance across long-term projects.
- Ensures reproducibility for content pipelines, asset libraries, and enterprise workflows.
8. Ideal Use Cases
- Storyboarding → full-scene generation
- Product or app demos visualized from text
- Educational and explainer videos
- Social media content creation
- Creative ideation and prototyping
