Bananas for AI: Inside Google’s Nano Banana Image Model

⚡ Benchmarks & Performance

• Leaderboard Success
  Nano Banana was first tested anonymously on competitive benchmarking platforms, where it quickly rose to the top of the “Battle Mode” rankings. Users consistently voted its outputs superior to rivals, especially in identity preservation and edit fidelity.
• Low Latency
  The model achieves 1–2 seconds per generation or edit, a significant leap over earlier AI systems that often took 10–15 seconds. This responsiveness makes it practical for real-world creative workflows.
• Cost Efficiency
  Pricing is designed for both scale and accessibility: approximately $30 per 1M output tokens, which averages out to around $0.04 per image. This positions it as one of the most cost-effective high-end image editors available.
