OpenAI's ChatGPT web app update shows references to 'GPT-5', 'gpt-5-pro', and 'gpt-5-thinking', alongside new 'gpt-4o' variants and internal model search features, hinting at future model releases and internal tooling.

READY TO POST:

looks like openai just dropped a new chatgpt web app update, and deep in the code there are multiple mentions of 'gpt-5' and 'gpt-5-pro'. could this be what they're testing internally?

interesting to see 'gpt-4o-mini' and various 'gpt-4o-gdrive' models pop up in the latest chatgpt web app bundle. they're clearly experimenting with more specialized and smaller variants.
