Inputs (12)
| Name | Type | Default | Description |
|---|---|---|---|
| api_key | STRING | NanoBanana - API key. Leave blank to use GEMINI_API_KEY env var. | |
| model | COMBO | gemini-3.1-flash-lite-preview | NanoBanana - model for vision analysis. |
| custom_model | STRING | Override with a custom model ID. | |
| prompt | STRING | Describe this image. | What to ask about the image(s). |
| system_instructionopt | STRING | System instruction to guide analysis. | |
| temperatureopt | FLOAT | 0.100–2 | Controls randomness. Lower = more focused analysis. |
