Hamza(@hamza72510):Codex’s /goal command can be used in really creative ways. I used it to iteratively update a robotic RL reward function and fine-tune a humanoid policy to walk like the reference GIF. Codex ran a simple loop: edit reward → train → evaluate → compare rollout video → repeat, while preserving the RL architecture and trying to match the reference behavior. @OpenAIDevs @OpenAI @Codex
