Which plan to pickStart on Pro to see which jobs it handles well for you. If you hand it real work most days you will hit the limits, and Max is the plan that makes it a daily tool.Hermes itself costs nothing. If you already pay for an AI model's API, plug that in. If you'd rather not collect separate keys for models, search and browsing, Nous Portal Plus at $20 a month covers light use. There's also a free Portal tier limited to free models.It's all free. Sign in with a free Opera account if you want your chats saved and more images; otherwise just download it and click Ask AI. Opera sells a separate VPN Pro, but you don't need it for the AI.
