Nano Banana 2 vs Nano Banana Pro

Nano Banana 2 costs $3.00 per 1M input tokens and $30.00 per 1M output tokens, whereas Nano Banana Pro costs $3.50 input and $35.00 output. Overall, Nano Banana 2 is the more cost-effective model for high-volume API pipelines. Both models support prompt caching discounts of up to 90% for repeated prompt prefixes.

Nano Banana 2 supports a context window of 131K tokens (~98k words), while Nano Banana Pro supports 66K tokens (~49k words). Therefore, Nano Banana 2 can process more textual data and document context in a single prompt.

Nano Banana 2 scores at the frontier of coding benchmarks, while Nano Banana Pro scores competitively for software generation. For complex autonomous debugging and agentic engineering, Nano Banana 2 provides robust code generation and tool calling.

Nano Banana 2 features native chain-of-thought extended thinking mode with configurable reasoning effort. In contrast, Nano Banana Pro provides chain-of-thought reasoning depth for complex math and science.

Nano Banana 2 generates approximately 65 tokens per second, while Nano Banana Pro delivers 50 tokens per second. In latency-sensitive production environments, Nano Banana 2 provides faster time-to-first-token (TTFT) and higher streaming response velocity.

Yes! High-efficiency architectures route high-frequency routine classification and conversational tasks to Nano Banana 2 to save operational costs, and dynamically escalate complex architectural queries or reasoning tasks to Nano Banana Pro. This tiered routing pattern cuts overall API bills by up to 70%.
