Free, no. But low cost, yes. We had a lot of problems with the free model because users expected more out of it than it was capable of.
We put $$$ signs next to the models to show their cost level. I've personally been taking Claude Haiku for a spin because it's pretty good and cheap. It can do a lot for a few bucks. I can test an idea and it can even pull some of them off. When you're ready, you can ratchet it up to a higher cost/more powerful model.
Or maybe start with Claude Sonnet 4.5 to do the heavy lifting, then switch to Haiku for follow-up prompts. There's no "right" way to vibe code. Just different schools of thought.
I personally would get hung up in Tybalt some of the time. Haiku is my frugal hack for now. There are an overwhelming amount of models.
