Deep dive
The capability footprint differs most on vision: Nano Banana 2 (Gemini 3.1 Flash Image), multimodal input: Nano Banana 2 (Gemini 3.1 Flash Image), and reasoning mode: Nano Banana 2 (Gemini 3.1 Flash Image). Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, DeepSeek V3 0324 lists $0.27/1M input and $1.12/1M output tokens on the cheapest tracked provider, while Nano Banana 2 (Gemini 3.1 Flash Image) lists $0.50/1M input and $60/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts DeepSeek V3 0324 lower by about $17.83 per million blended tokens. Availability is 3 providers versus 1, so concentration risk also matters.
Choose DeepSeek V3 0324 when long-context analysis, larger context windows, and lower input-token cost are central to the workload. Choose Nano Banana 2 (Gemini 3.1 Flash Image) when reasoning depth are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
