I got a bit further with my harness for running Qwen 3.6 model on Codex. While testing, analyzing, and building the harness, I evolved TBG(O)llama-swap into a full forensic UI bridge and LLM analytics tool where every harness finding, modification, correction, tool call, reasoning step, and execution flow is fully visible. This level of transparency was necessary to identify the behavioral differences between native OpenAI models and Qwen 3.6, and to fine-tune the harness accordingly. The video shows a full Codex run on Qwen 3.6 running on a single NVIDIA GeForce RTX 5090.
