🧠 Using OpenRouter API
The OpenRouter API provides unified access to a wide range of large language models — including GPT, Claude, Gemini, and many others through a single API interface. Billed through fal.
🚀 Usage with OpenAI Client
from openai import OpenAI
import os
client = OpenAI(
base_url="https://fal.run/openrouter/router/openai/v1",
api_key="not-needed",
default_headers={
"Authorization": f"Key {os.environ['FAL_KEY']}",
},
)
response = client.chat.completions.create(
model="google/gemini-2.5-flash",
messages=[
{"role": "user", "content": "Write a short story (under 200 words) about an AI that learns to dream. Use vivid sensory details and end with a surprising twist that makes the reader feel both awe and melancholy."},
],
)
print(response.choices[0].message.content)
