I must be missing something about Gemini. When I use the web UI it won't even let me upload source code files directly. If I manually copy some code into a directory and upload that I do get it to work, but the coding output is hilariously bad. It produces ludicrously verbose code that so far for me has been 200% wrong every time.
This is on a Gemini 2.5 Pro free trial. Also - god damn is it slow.
For context this is on a 15k LOC project built about 75% using Claude.
