Is ChatGPT more up to date than GPT3.5?

When I do a side by side comparison of data:

I get two separate answers. Does ChatGPT contain knowledge that GPT3.5 does not? Is the version of davinci in the playground not 3.5?

We’re not entirely sure about ChatGPT, but we think it’s possibly GPT-3.5.

The latest model in Playground is TD3 (Text-Davinci-003), which is also “kinda-sorta” a GPT-3.5 version?

Me and others are fairly certain they’re different models, though.

Hope this helps.


I was personally under the impression that text-embedding-ada-002 was the only available model built on GPT-3.5

Edit: Shows what I know!

So you don’t think any of the completion endpoints are 3.5?

Edit: wrong phrase

I mean, maybe TD3 (text-davinci-003) is GPT-3.5 (although unofficially…)

The model naming convention is evolving… Things are moving so quickly now…

ETA: I defer to the post below with a source! Thanks.So hard to keep up these days!


“GPT 3.5” is what they’ve started calling their models that combine code and text completion.

text-davinci-003, text-davinci-002 and code-davinci-002 are all considered “GPT 3.5”


This is perfect! Thanks all!
