+# AI SDK - OpenAI Compatible Provider
+
+This packge aims to speed and support the implementation of new
+OpenAI-compatible providers. The intent is to allow more effective code sharing
+across multiple concrete provider implementations.
+
+The primary OpenAI provider is heavier-weight than what this package offers.
