The March blog post mentions text-davinci-003, but you only say text-davinci-002 was released in March. The latter seems more plausible, since it matches with the newsletter OpenAI sent out at the end of November: “New GPT-3 model: text-davinci-003”.
Starting today, you can access text-davinci-003 through our API and playground at the same price as our other Davinci base language models ($0.0200 / 1k tokens).
So I think the “March” blog post has probably been edited and isn’t decisive evidence that code-davinci-002 (the GPT 3.5 base model) actually came out in March.
