Inputs (24)
| Name | Type | Default | Description |
|---|---|---|---|
| api_key | STRING | API key for accessing OpenRouter API | |
| model_name | STRING | google/gemini-2.5-flash-image-preview | OpenRouter model name for image generation |
| system_prompt | STRING | System-level prompt that affects the overall image generation style | |
| prompt | STRING | Main prompt content for image generation | |
| temperature | FLOAT | 1.000–2 | Sampling temperature, higher values produce more random outputs |
| top_p | FLOAT | 0.000–1 | Sampling probability threshold, controls output diversity |
| max_tokens | INT | 81920–32768 | Maximum number of tokens in the generated text |
| retry_count | INT | 1 | Number of retries when request fails |
| provider | COMBO | auto | Infrastructure provider preference |
| provider_list | STRING | Provider list (comma separated, e.g: 'openai,azure,together'), empty means use provider | |
| chat_template | STRING | <-system-> {{system_instruction}} <-/system-> <-user-> {{prompt}} <-/user-> | Content template for the image generation prompt |
| proxy_url | STRING | 代理URL，格式: protocol://user:pass@addr:port，支持http,https,socks5,socks5h | |
| seed | INT | -1-1–2147483647 | Random seed for generation (-1 for random) |
| aspect_ratio | COMBO | auto | Aspect ratio for generated images |
| timeout | INT | 00–2147483647 | Timeout for the request in seconds, 0 means no timeout |
| image_size | COMBO | 1k | Image size for the generated image (gemini only for now) |
