🛠️ Codex Pooler: Self-Hosted Codex API Gateway

This is a self-hosted API gateway written in Elixir, designed specifically for OpenAI Codex and similar code-generation models. Its main purpose is to provide a unified interface for teams, AI agents, or individual developers to manage and route code-generation requests, supporting integrations with AI coding tools like Aider and Continue. When rolling out AI coding assistants within a team, managing API keys, controlling concurrent requests, and monitoring usage can be cumbersome. This project provides a lightweight middle layer that makes it easier for teams to share and route underlying model resources, fitting the needs of development teams with custom infrastructure requirements.
