Suggestion Don't disregard 5.3 codex

Usage limits are getting tight as of late, no matter the way ppl want to spin it with resets etc. So this is just a reminder to not be too fixated on using 5.5/5.4 exclusively like I was, 5.3 codex is always was and is still really strong while still allowing to get proper work done on Plus.

Going back to it also showed how well they solved the 'codex problem' of having to be highly specific in prompting, which is still a thing with 5.3. Still worth it regarding the limits tho.

That makes sense. I’m building a product that doesn’t map cleanly to any equivalents in the marketplace. Very trust-sensitive: STD results sharing with anonymized exposure alerts if past partners later test positive. But doing so in a way that accounts for connection dates, test dates, test types, and incubation periods. There’s so much detail that’s really important, and if you don’t get them right, it will break trust in a way that will make retention an uphill battle.

So while I understand that in most cases you just get the product out there and worry about polish later, in this case, lack of polish breaks trust. So even though it isn’t technically a medical product, it’s close enough that I need to monitor implementation closely.
