Simon Willison Creates Custom Codex Pet Pedalican with GPT-5.6
Simon Willison accidentally activated a pet in Codex Desktop and then created his own custom pet called Pedalican, a pelican on a bicycle. The process used GPT-5.6 Sol xhigh and gpt-image-2 to generate sprite assets. Willison documented the entire process, including generated images, sprite sheets, and GIFs, and shared the open-source skills on GitHub.
