| top_p | number | Nucleus sampling parameter - the model considers the results of the tokens with top_p probability mass. (0.1 means only the tokens comprising the top 10% probability mass are considered.) | 0 ≤ n ≤ 1 · default: 1 |
| prompt | string | The prompt to send to the model. Do not use if using messages. | |
| messages | object[] | A JSON string representing a list of messages. For example: [{"role": "user", "content": "Hello, how are you?"}]. If provided, prompt and system_prompt are ignored. | default: [] |
| image_input | string[] | List of images to send to the model | default: [] |
| temperature | number | Sampling temperature between 0 and 2 | 0 ≤ n ≤ 2 · default: 1 |
| system_prompt | string | System prompt to set the assistant's behavior | |
| presence_penalty | number | Presence penalty parameter - positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics. | -2 ≤ n ≤ 2 · default: 0 |
| frequency_penalty | number | Frequency penalty parameter - positive values penalize the repetition of tokens. | -2 ≤ n ≤ 2 · default: 0 |
| max_completion_tokens | integer | Maximum number of completion tokens to generate | default: 4096 |
