In 2025, AI tools like Google’s Nano Banana Pro (powered by Gemini 3 Pro) are judged on real metrics: generation speed, prompt fidelity (how well it follows instructions), character consistency (same face across images), text rendering accuracy, and visual quality at high resolutions. We pulled data from independent reviews, official specs, and community tests to compare Nano Banana Pro against Mid-journey v6 and DALL-E 3.
No single standardized benchmark exists yet (like GLUE for NLP), but aggregated 2025 data shows Nano Banana Pro leading in pro workflows.
Speed Benchmarks
Tested on complex prompts (e.g., “cyberpunk cityscape with multilingual neon signs”) across hardware (RTX 4090 GPU equivalents).
Key Insight: Nano Banana Pro’s Gemini 3 optimisation crushes latency – ideal for creators iterating 50+ images/day.
Average Generation Time for 2K and 4K Images
| Tool | Avg. Time (2K Image) | Avg. Time (4K Image) | Notes |
