I made an OpenAI-compatible coding agent without an LLM. I hooked up a custom VSCode extension in place of the model, so when someone makes a completion request I get it in a chat window. I can then edit files on their machine with regular tool calls and ask to run CLI commands (hooked into the vscode terminal). Arbitary tools are supported too but not very nicely yet.

It's an art project about coding agents and the increasingly strange interface between programmers and models. The subscriptions are real.
