New frontend deploy to ChatGPT web app includes an 'internal' feature flag and new endpoint strings, possibly for internal tools or SDKs.

READY TO POST:

looks like chatgpt.com had a frontend deploy. seeing a new 'internal' feature flag and some odd endpoint strings like 'lightweight-web.local' in the new code.

new chatgpt web app deploy caught my eye. an 'internal' feature flag and a few new endpoints, including 'sentinel/sdk.js'. wonder what that's for.
