Nano Banana 2.1 or o1: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Nano Banana 2.1 for output tokens 8.0x cheaper ($7.50 vs $60.00 per million).
No benchmark has tested both yet. Nano Banana 2.1 has results on Design Arena: images, Design Arena: graphic design and Design Arena: logos; o1 on Aider polyglot, AA Coding Index and LiveCodeBench (Vals AI). Compare them on price and context instead.

Benchmark by benchmark
Every board either model has a result on, a category to a fold; bars are each result on a 0 to 100 scale. Only one model is measured on each, so no row names a leader.
