DeepSeek V3 0324 vs Nano Banana 2.1: which should you choose in 2026?

DeepSeek V3 0324 (by DeepSeek) and Nano Banana 2.1 (by Google) are compared below. Here is how they stack up on benchmarks, price, and capabilities, and which one to pick in 2026.

There are not enough shared, protocol-compatible benchmark results to declare a performance leader.

Choose DeepSeek V3 0324 if…

  • • your own prompt tests favor its output; shared comparable evidence does not identify a unique advantage

Choose Nano Banana 2.1 if…

  • • you need a model with explicit reasoning support
  • • you need image inputs
  • • you need image generation

The benchmark count includes only results measured with a matching benchmark version and protocol. Arena scores are shown separately. Missing, preliminary, and incompatible data is not treated as a controlled win. Published point-score comparisons are labeled separately when protocol details are incomplete. For text-output models, the verdict also compares token pricing and context windows.
