How it fits together

Four things, and it helps to keep them apart.

Chat, container, plan and creditA chat uses one model at a time and can be attached to a container, a Linux machine whose files persist. One container can serve several chats. Each answer is a model request, and credit pays for it. The plan sets the container's hardware limits and adds some credit every month, but it does not pay for model requests itself.cores, memory, disk,run length, portsattach; one containercan serve several chatseach answerpaysadds some crediteach monthPlansets the hardwareChatone model at a timeCreditprepaid, for modelsContainera Linux machine,files persistModel requestpaid per request
Credit pays for the chat's model requests; the plan sets the container's hardware and only tops up credit.
Diagram as text
  1. A chat is a conversation with one model at a time, and you can change the model.
  2. A chat can be attached to a container. One container can serve several chats, and its files persist.
  3. Each answer is a model request that is paid per request.
  4. Credit, prepaid money, pays for those requests.
  5. The plan sets the container's limits: cores, memory, disk, how many containers run, how long an agent may run and how many public ports.
  6. Every paid plan also adds some credit each month. The plan itself does not pay for model requests.

The four things

You use

Models

Chat

The conversation. It belongs to you.

one model at a time, changeable

Hardware

Container

A real Linux machine, independent of any chat. You can attach the same container to several chats.

its files persist

You pay

Models

Credit

Prepaid money for model usage. Separate from the plan, though every paid plan adds some each month (see Plans and Credit).

paid per request

Hardware

Plan

What hardware you may use.

  • cores
  • memory and disk
  • how many containers run at once
  • how long an agent may run
  • how many public ports

The important consequence

Plan Model usage

A plan does not pay for model usage. It only adds some credit each month.

Credit Hardware

Credit does not buy hardware.

They are two meters because they are two different costs.

What survives closing the tab

Keeps running
  • A chat, an agent or a /goal run once you have sent it
  • A terminal session you can reattach to later
  • A container's files, across restarts
Needs your action
  • Stopping a run: the stop button or an explicit abort
  • Nothing stops it just because the tab closed or the page reloaded
