I warn you that it is addictive.

I am using DS and MiMo on Pi.dev, and I don't see myself going back to OpenAI. They are criminally cheap in a way that I don't care to spend tokens. That leaves me space to experiment.

And in terms of capability, well... I use Sonnet and Opus at work (provided by my employer), and I see no difference in terms of what I can achieve. Well, besides Claude costing dozens of times more.
