Strengths for Content Creation

GPT-5.5

OpenAI

1. 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.

Nano Banana 2

Google

1. High-efficiency counterpart to Gemini 3 Pro Image

  • Google describes Nano Banana 2 as the high-efficiency counterpart to Gemini 3 Pro Image.
  • Optimized for speed and high-volume developer use cases rather than maximum pro-grade fidelity.

2. Native image generation + understanding

  • Accepts text and image inputs and can output both text and images in a conversational workflow.
  • Useful for quick iteration, editing, remixing, and interactive visual applications.

3. Strong throughput with practical image controls

  • Supports up to 14 input images per prompt, 128 k input tokens, and 32,768 output tokens.
  • Handles multiple aspect ratios and can generate or edit images while keeping latency and cost lower than higher-end image models.

4. Grounded, developer-friendly image workflows

  • Supports Google Search grounding and Content Credentials (C2PA) for image outputs.
  • All generated images include SynthID watermarking as part of Google's native image stack.
