I've been using DS4F+Pi with great results, but I think one thing that helps is at the end of my prompt I'll tell it how to verify it, e.g. "Make sure the compose file works by running it locally (use self-signed certs if required)".

The argument could be made that "the model should be smart enough to figure it out" , and maybe DS4 isn't. But with just a bit of steering you can get the correct result for like 1/10th the cost, or even cheaper.
