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.
Pricing coverage is uneven: Code Davinci 001 has no token price sourced yet and Nano Banana 2 (Gemini 3.1 Flash Image) has $0.50/1M input tokens. Provider availability is 0 tracked routes versus 1. Treat unknown pricing as an integration gap, then verify the route you will actually call before estimating production spend.
Choose Code Davinci 001 when coding workflow support are central to the workload. Choose Nano Banana 2 (Gemini 3.1 Flash Image) when reasoning depth and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions.
FAQ
Is Code Davinci 001 or Nano Banana 2 (Gemini 3.1 Flash Image) open source?
Code Davinci 001 is listed under Proprietary. Nano Banana 2 (Gemini 3.1 Flash Image) is listed under Proprietary. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.
Which is better for vision, Code Davinci 001 or Nano Banana 2 (Gemini 3.1 Flash Image)?
Nano Banana 2 (Gemini 3.1 Flash Image) has the clearer documented vision signal in this comparison. If vision is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for multimodal input, Code Davinci 001 or Nano Banana 2 (Gemini 3.1 Flash Image)?
Nano Banana 2 (Gemini 3.1 Flash Image) has the clearer documented multimodal input signal in this comparison. If multimodal input is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for reasoning mode, Code Davinci 001 or Nano Banana 2 (Gemini 3.1 Flash Image)?
Nano Banana 2 (Gemini 3.1 Flash Image) has the clearer documented reasoning mode signal in this comparison. If reasoning mode is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
