Reading through that article, the specific Davinci/Curie models they seem to be referring to are called the following: 'text-search-davinci-001', 'text-search-curie-001', 'text-similarity-davinci-001' and 'text-similarity-curie-001'.

Are you sure these have anything to do with 'text-davinci-003' or 'text-curie-001'?

Will have to agree with everyone here that OpenAI is good at being extremely confusing. It seems like the logic might be something along the lines of the 'text-search' portion being the actual type of the model, while the 'curie-001' / '<name>-<number>' format is just a personalized way of expressing the version of that type of model. And the whole 'GPT<number>' category used to be a sort family of models, but now they've just switched it to the actual name of the newer gargantuan LLMs. Then, because the 'GPT<number>' models are now that different thing altogether these days, the newest 'text-embedding' model is just named 'ada-<number>' because it's on that iteration of the 'text-embedding' type of model, adhering to the older principle of naming their models? Not sure, ha. Definitely feels like doing some detective work.
