Thinking and effort modes toggle.

A feature that lets you choose how hard a model things or the effort put in, however the more effort, the larger the credit deduction based on the model. For example say the normal thinking mode/effort prior to this update was medium: would deduct the same amount credits as the model does currently, however if the user selects low effort/low thinking it would deduct less, if the user chooses higher effort or thinking it would cost more points then per usual
