How this price is scoped: This model publishes two per-token output rates: $3.00 per 1M for text and thinking tokens, and $60.00 per 1M for generated image tokens. The tracked output price is the image rate, because image generation is what the model is bought for — cost a text-only turn at $3.00 instead. Google's own equivalents: 747 output tokens for a 0.5K image ($0.045), 1120 for 1K ($0.067), 1680 for 2K ($0.101) and 2520 for 4K ($0.151).
