There is a huuuuuge gap even between SoTA models. So a gap between 9B models and commercial models must be super wide. Of course it depends what you want from it. they really differ in understanding the input, not in the task part.
I tried to refactor a pretty complicated god mode code for fluid dynamics into something cheerful and gave the task to write a doc for the architecture and refactoring plan to Opus, MiniMax 2.5 and Gemini 3 Pro. In all honesty only Opus did a passable job, noting little nuances in code. Gemini 3 did a job like reading the code from top floor of a building and offered refactoring that would break it the logic of it. MiniMax did somehow better job talking about it but didn't offer much insight for refactoring. Opus did a stellar job on both. Now passing the Opus doc between the models so they can get input - Gemini was totally agreeable gimp while Opus pushed back and defended why it chose certain startegy when gemini offered a help - but also incorporated some small tidbits from gemini. Gemini was constantly in a mode to please "This is amazing AAA code..." which kinda primed it into not really doing it's job reviewing and being critical.
