Pricing questions
Can I switch plans later?
Yes — upgrade the moment you need more, and cancel just as easily. Changes take effect right away.
What's the difference between the models?
Sol Mini is fastest for everyday questions, Sol is a balanced all-rounder, and Sol Max is the most capable for deep, complex work. Higher plans unlock the stronger models.
What does 'effort' mean?
Effort lets you trade speed for depth. Quick gives short, fast answers; Deep and Max push Sol to think harder and write more thorough responses.
What counts as unlimited?
Business and Enterprise remove the daily message cap, so your team can chat as much as you need. Fair-use applies to keep things running smoothly for everyone.
How do I cancel?
