Difference between davinci:2020-05-03 and text-davinci-002

As the title says, I am confused between these 2.
If I select davinci for fine-tuning, it seems to pick davinci:2020-05-03. When I get the list of models, davinci:2020-05-03 also comes up as an older version to davinci:2020-05-03, but in the documentation, text-davinichi-002 is said to be the most advanced with data up to Jun 2021.

  1. Can someone please clarify this?
  2. Is davinci:2020-05-03 also trained up to 2021 and the only difference is that it doesn’t support instruct hence better for finetuning?
