A funded OpenRouter account. OpenRouter lists the model at $1.25 per million input tokens and $4.25 per million output tokens. You buy credit on the site and spend it as you chat. We found no free way to chat with this model today, and we looked.
A short conversation may cost only a few cents, depending on how many tokens it uses.
A browser and about 5 minutes, plus a few more if you sign up. Nothing to install.
Running it at home instead takes two Apple M5 Ultra Mac Studios. What that means, below.
