This is Part 1 of "Building My Own Coding Agent Based on Codex (Open Source)."

Since I usually struggle with expensive token fees while developing, I often wonder if I can develop using a local machine on a spare computer.

Vive Coding tools are typically built assuming the powerful models of frontier companies.

Because local models are inherently weak, I felt that the agent itself needed to be tailored to the local model.

This is the first time I am creating a video documenting my personal usage and development log, rather than a lecture.

In this first session, I will demonstrate the principles and methods for achieving performance of over 80 tokens per second even with a local model, and I will also build a Tetris game using the agent I created myself.
