About Amp

Amp is a frontier AI agent designed for developers who want maximum capability from their coding assistant. It operates across web, terminal, and mobile devices, with agents running locally or in 'orbs'—remote machines that continue working even when the laptop is closed. Amp emphasizes staying on the cutting edge by rapidly adopting new models and workflows, and it offers a minimalist, opinionated experience that removes unnecessary features. It is extensible via plugins, supports event-driven orbs, multiplayer team control, scheduled agent tasks, Slack integration, and includes a meta-agent helper named Puck. Pricing is subscription-based (Megawatt $20/month, Gigawatt $200/month) or pay-as-you-go, with options to link third-party subscriptions like ChatGPT or X Premium to reduce token costs.

FAQ

Do I need to subscribe to use Amp?

No, you can use Amp on a pay-as-you-go basis where you pay API pricing for everything. However, subscriptions are the most cost-effective way to use Amp.

What if I use all the included usage on a subscription?

You can add paid credits to continue using Amp until your subscription usage replenishes at the end of each monthly period.

Can I use high and ultra modes on the Megawatt plan?

Only if you add additional paid credits. The Megawatt plan by default gives limited usage of low and medium agent modes. High and ultra modes are available on the Gigawatt plan or with extra credits.

Are there any additional fees for using a ChatGPT subscription?

No. Amp subscribers pay no per-token fees when using a linked ChatGPT subscription or other third-party subscription. You can use as many tokens as your third-party subscription allows.
