gemini_image.vertex(
  image = NULL,
  prompt = "Explain this image",
  type = "png",
  tokens = NULL,
  temperature = 1,
  maxOutputTokens = 8192,
  topK = 40,
  topP = 0.95,
  seed = 1234
)

Arguments

image: The image to generate text
prompt: A character string specifying the prompt to use with the image. Defaults to "Explain this image".
type: A character string specifying the image type ("png", "jpeg", "webp", "heic", "heif"). Defaults to "png".
