Prototype your AI ideas instantly, without the OpenAI bill.
[!IMPORTANT]
This is an OpenAI API Simulator, not the actual OpenAI service. It is designed solely for verification and prototyping of AI workflows using your local VS Code models.
💡 Why use this?
Validate your prompt logic, LangChain workflows, or AI scripts for "free" by leveraging your existing GitHub Copilot subscription. Perfect for testing ideas before you commit to a commercial API subscription.
⚡ Quick Start
Launch: Open the sidebar panel, select a model, and click Start Server.
Connect: Update your app's configuration:
Base URL: http://127.0.0.1:9090/v1
API Key: sk-test (anything works)
Model: The ID shown in the bridge (e.g., copilot-gpt-4o)
🐍 Python Example
from openai import OpenAI
client = OpenAI(base_url="http://127.0.0.1:9090/v1", api_key="sk-test")
# Uses your local VS Code model!
response = client.chat.completions.create(
model="copilot-gpt-4o", # The model selected in extension will actually work, not the one in the request.
messages=[{"role": "user", "content": "Hello!"}]
)
