VM0 positions Claude Fable 5.1 as a core agent model for orchestration, code-touching work and other steps where a wrong answer is expensive.
Credits and the $$$$ price tier
VM0 prices every Built-in model on a four-step credit scale — $, $$, $$$, $$$$ — shown as a badge in the model picker and on the price tier line of zero model ls. Claude Fable 5.1 sits at $$$$. That tier is what you spend from your VM0 credit balance; the vendor list price in the table above is what the upstream provider charges before VM0 converts it into credits.
