Gemini API: Multimodal AI at Fraction of GPT-4o Cost
Why Gemini?
Setup
bash
pip install google-generativeai
python
import google.generativeai as genai
genai.configure(api_key="your-key")model = genai.GenerativeModel("gemini-2.0-flash")
response = model.generate_content("Explain quantum computing")
print(response.text)
Models
Image Analysis
python
import PIL.Image
image = PIL.Image.open("screenshot.png")
response = model.generate_content([image, "Identify UI issues"])
print(response.text)
Video Analysis
python
video = genai.upload_file(path="demo.mp4")
model = genai.GenerativeModel("gemini-1.5-pro")
response = model.generate_content([video, "Summarize this demo"])
Google Search Grounding (Unique to Gemini)
python
grounding = genai.protos.Tool(
google_search_retrieval=genai.protos.GoogleSearchRetrieval()
)
model = genai.GenerativeModel("gemini-2.0-flash", tools=[grounding])
response = model.generate_content("What are the latest AI regulations in 2026?")
Response includes real web citations
Cost at 1M tokens/day
Gemini Flash is 15-20x cheaper. Benchmark for your use case before committing.
