You can now use OpenAI-compatible client libraries and tools with AI Gateway through a simple URL change, allowing you to access 100s of models with no code rewrites required.
Here is a Python example with the OpenAI client library:
from openai import OpenAI
client = OpenAI( api_key='my-ai-gateway-key', base_url='https://ai-gateway.vercel.sh/v1')
stream = client.chat.completions.create( model='anthropic/claude-4-sonnet', messages=[ { 'role': 'user', 'content': 'Write a one-sentence bedtime story about a unicorn.' } ], stream=True,)
for chunk in stream: content = chunk.choices[0].delta.content if chunk.choices[0].delta.content else None if content: print(content, end='', flush=True)print()This makes it easy to keep your current tools and workflows while improving uptime, tokens per minute, quotas, and reliability via provider failover and adding observability through the AI Gateway.
