> How plans work All plans give you access to every model. Your choice of model and the size of your tasks affect how quickly you use your allowance. Daily and weekly limits apply, along with a monthly allowance. You can see how much you've used and when each limit resets on the Usage page. More expensive models have an additional monthly limit; which models count depends on your plan. If you reach it, you can keep using other models within your remaining allowance. If you use up your included usage, you can switch to an available free model, wait for your allowance to reset, or continue with purchased pay-as-you-go credits. > FAQS How much more usage do Super and Ultra include? Super gives you substantially more included usage than Plus, and Ultra more again. Each plan card above lists its included Cloud agent size. How much work you can do depends on the models you choose and the size of your tasks. What counts toward usage? Model and included tool usage in Hermes Agent count toward your allowance when you sign in with your Nous account. Hosting for one Cloud agent is included as well. API-key requests and additional Cloud agents use pay-as-you-go credits. When does my usage reset? Daily usage resets after 24 hours, and weekly usage after seven days, starting when you first use each window. Your monthly allowance and large-model allowance reset with your billing period. Your Usage page shows the exact reset times. These limits apply together: a daily reset won't restore included usage if you've reached your weekly or monthly limit. What happens when I reach a limit? You can wait for the reset or switch to an available free model. Turn on Keep going on credits to continue using paid models with your pay-as-you-go balance. Leave it off and Hermes won't spend those credits when your included usage runs out. If you reach only the large-model limit, other models remain available within your remaining allowance. What happens to my existing subscription? When you switch, unused subscription credits carry over as pay-as-you-go credits, up to one month of your current plan's credits. Switching to a plan at the same price takes effect immediately with nothing to pay that day. Upgrades charge the price difference; downgrades take effect at the end of your billing period. Once you switch, you can't return to a legacy paid plan.

We've revamped Hermes Agent subscriptions. Every new plan now includes a cloud agent out of the box, and usage has daily and weekly limits instead of one monthly block of credits. Subscribers can switch to the new plans any time at portal.nousresearch.com/billing

Please be careful about downloading third-party apps. The official mobile apps are not in app stores yet, and apps that closely mirror Hermes branding are typically fraudulent and not legitimate community projects.
