 # Qiskit Code Assistant - OpenAI API compatibility
 
-Qiskit Code Assistant offers compatibility with a subset of the OpenAI API specification, specifically with the [completions API endpoints](https://platform.openai.com/docs/api-reference/completions). The goal of this compatibility is to allow third-party packages to connect to Qiskit Code Assistant seamlessly by using well-known AI-related libraries and methods such as [OpenAI](https://github.com/openai/openai-python), [LiteLLM](https://github.com/BerriAI/litellm), or others.
