You're thinking of the old "ada" GPT-3 model - the one that was a companion to "davinci" and "babbage".

I believe "text-embedding-ada-002" is entirely unrelated to those old GPT-3 models. It's a recent embedding model (released in December 2022 - https://openai.com/blog/new-and-improved-embedding-model ) which OpenAI claim is their best current best available embedding model.

I understand your confusion: OpenAI are notoriously bad at naming things!

Oh, thanks for clarifying!

Edit: looking at the press release, the improvement over old Ada is ... marginal? And Ada-01 is/was a poor performing model, tbh. I guess I'll have to run some tests, but at first sight it doesn't seem that wow-ey.

So just to be super clear, this is an embedding model. It generates no text. It’s not outputting words.

Maybe I am assuming incorrectly, but I think the poor performance you are referring to is the old Ada completion model, where the output is text. That was poor indeed.

This article is not kind to the old ada embeddings model:

If the new ada model only has marginal improvements, it seems open source is way to go.
