I felt the same way about openai's text-davinci-002 and code-davinci-002 (gpt-3.5). They were amazing completion models and openai basically dumped them with no equal cost or equal performance replacement. Instead all their models are opaque with no ability to work in completion mode where one actually controls the text input to the model.

These days no company even has completion models where one controls the text input fully. Worthless.
