When generating images via Gemini API, ALWAYS use gemini-3.1-flash-image-preview (Nano Banana 2). Never use older models. Use the Python SDK:
from google import genai
from google.genai import types
client = genai.Client(api_key=os.environ["GEMINI_API_KEY"])
response = client.models.generate_content(
model="gemini-3.1-flash-image-preview",
contents=[prompt],
config=types.GenerateContentConfig(
response_modalities=['TEXT', 'IMAGE'],
image_config=types.ImageConfig(aspect_ratio="16:9", image_size="2K"),
),
)~30 seconds. Free. No account. Every finding cites a rule and a line of evidence.
