Yesterday's post covered the basic Vector Engine API offer. Today's note is more practical: how to move an existing OpenAI SDK integration to an OpenAI-compatible API relay with the smallest possible code change. The useful part is that most apps already have the right abstraction. If your code uses the OpenAI SDK, you usually only need to change the API key and the base URL. What Changes In a direct OpenAI setup, the SDK sends requests to the default OpenAI endpoint. With Vector Engine API, you keep the same SDK shape and point it at: https://www.vectronode.com/v1 Enter fullscreen mode Exit fullscreen mode That means your existing chat completion flow can stay familiar: Same messages array Same model field Same chat.completions.create call Same environment-variable based deployment pattern Python Migration Before: from openai import OpenAI client = OpenAI ( api_key = " YOUR_OPENAI_KEY " ) Enter fullscreen mode Exit fullscreen mode After: import os from openai import OpenAI client = OpenAI ( api_key = os .…
