| If you want to add data URL example too, something like this works, but it's nice-to-have: FILEPATH = os.path.join(os.path.dirname(__file__), "media/image_bison.jpg") def image_to_base64(image_path): with open(image_path, "rb") as image_file: encoded_string = base64.b64encode(image_file.read()).decode("utf-8") return encoded_string @function_tool def fetch_random_image() -> ToolOutputImage | ToolOutputImageDict: """Fetch a random image.""" print("Image tool called") b64_image = image_to_base64(FILEPATH) return { "type": "image", "image_url": f"data:image/jpeg;base64,{b64_image}", "detail": "auto", } |
