ChatGPT's web app update includes references to 'GPT-5', 'gpt-4l', and several 'gpt-4o-gdrive' models, alongside numerous internal feature flags and endpoints.
READY TO POST:
looks like openai is testing a 'gpt-5' internally, along with a 'gpt-4l' and a bunch of 'gpt-4o-gdrive' variants. interesting to see what sticks!
new chatgpt web app code hints at 'gpt-5' and 'gpt-4l'. lots of internal model names appearing in the frontend bundle. could be early testing!
