​
Multimodal Input

Gemini supports mixed text and image input: 
import PIL.Image

# Load image
img = PIL.Image.open('image.jpg')

# Send text and image
response = model.generate_content([
    "描述这张图片中的内容",
    img
])

print(response.text)

​
Streaming Output

response = model.generate_content(
    "写一个关于AI的故事",
    stream=True
)

for chunk in response:
    print(chunk.text, end="")

​
Safety Settings

Control content filtering levels: 
from google.generativeai.types import HarmCategory, HarmBlockThreshold

response = model.generate_content(
    "你的提示词",
    safety_settings={
        HarmCategory.HARM_CATEGORY_HATE_SPEECH: HarmBlockThreshold.BLOCK_ONLY_HIGH,
        HarmCategory.HARM_CATEGORY_HARASSMENT: HarmBlockThreshold.BLOCK_ONLY_HIGH,
    }
)
