Claude Sonnet is my favorite, despite occasionally going into absurd levels of enthusiasm.
Opus is... Very moody and ambiguous. Maybe that helps with complex or creative tasks. For conversational use I have found it to be a bit of a downer.
As the companies sprint towards AGI as the goal the floor for acceptable customer service has never been lower. These two concepts are not unrelated.
I’m not suggesting this is sufficient, I’m just noting there is somewhere in the user interface that it is displayed.
Another possible reason is that they want to discourage users from using the product in a certain way (one big conversation) because that’s bad for content management.
Example prompts:
- “Modify my Push #2 routine to avoid aggravating my rotator cuff”
- “Summarize my progression over the past 2 months. What lifts are progressing and which are lagging? Suggest how to optimize training”
- “Are my legs hamstring or glute dominant? How should I adjust training”
- “Critique my training program and suggest optimizations”
That said, I would never log directly in ChatGPT since chats still feel ephemeral. Always log outside of ChatGPT and copy/paste the logs when needed for context.
Back in April 2025, Altman mentioned people saying "thank you" was adding “tens of millions of dollars” to their infra costs. Wondering if adding per-message timestamps would cost even more.
I would be very surprised if they don’t already store date/time metadata. If they do, it’s just a matter of exposing it.
if response == 'thank you': print('your welcome')
I just asked ChatGPT this:
> Suppose ChatGPT does not currently store the timestamp of each message in conversations internally at all. Based on public numbers/estimates, calculate how much money it will cost OpenAI per year to display the timestamp information in every message, considering storage/bandwidth etc
The answer it gave was $40K-$50K. I am too dumb and inexperienced to go through everything and verify if it makes sense, but anyone who knows better is welcome to fact check this.
I'll have to look into the extension described in the link. Thank you for sharing. It's nice to know it's a shared problem.
Now you’re going to the doctor and you forgot exactly when the pain started. You remember that you asked ChatGPT about the pain the day it started.
So you look for the chat, and discover there are no dates. It feels like such an obvious thing that’s missing.
Let’s not over complicate things. There aren’t that many considerations. It’s just a date. It doesn’t need to be stuffed into the context of the chat. Not sure why quality or length of chat would need to be affected?

This has been requested consistently since early 2023 on the OpenAI community forum, with hundreds of comments and upvotes and deleted threads, yet remains unimplemented.
Do any of you could think of a reason (UX-wise) for it not to be displayed?

Not a joke. To capture a wide audience you want to avoid numbers, among other technical niceties.

EDIT: It's not a new issue, and Asimov phrased it well back in 1980, but I feel it got much worse.

What does this even mean

I can imagine a legal one. If the LLM messes big time[1], timestamps could help build the case against it, and make investigation work easier.
