How to Use Gemini 2.5 Flash Image

Google offers access through multiple channels:

• Gemini API for integration
• Google AI Studio for rapid prototyping
• Vertex AI for enterprise-scale applications

Example Python snippet:

from google import genai
from google.genai import types

client = genai.Client()
prompt = "Futuristic city skyline at sunset, digital art style"
response = client.models.generate_content(
    model="gemini-2.5-flash-image",
    contents=[prompt],
    config=types.GenerateContentConfig(
        response_modalities=["IMAGE"],
        image_config=types.ImageConfig(aspect_ratio="9:16")
    )
)
# Display the generated image

Developers can feed input images plus text prompts for blending, transformations, or edits.
