Credits: what costs what

Gumloop · Practical · 8 min

Agents can do a lot of work per request; knowing where credits go keeps costs predictable.

Gumloop measures usage in credits. Unlike a fixed price per message, you pay for what the agent actually does, so a quick question costs far less than a long research task. (Prices and plan amounts change, so check your account for current numbers.)

What uses credits:

  • Chat & Reasoning: the model reading, thinking and writing. Bigger models and longer conversations cost more, and so does every connected tool, because tool descriptions are sent to the model too.
  • Tool calls: each successful app action. Failed calls are free. Some tools add their own fees.
  • Compute: time the agent spends actively working, such as running code or browsing. Waiting for you is free.
  • Brain searches and indexing.
  • An orchestration fee: a percentage on top for running the agent loop.

Where to see it: every task shows a running credit total; click it for a breakdown by type. Usage & Limits has detailed logs you can export, and you can set alerts when usage crosses a threshold.

How to spend less:

  • Use the simplest model that does the job well.
  • Start a new task for a new topic.
  • Attach only the connectors and abilities the agent needs.
  • Prefer built-in triggers over AI-created polling triggers where one exists.

Bring your own key (BYOK): on paid plans you can connect your own AI provider account, so model costs are billed by that provider instead; tool calls and compute still use credits. In shared agents, usage is usually charged to the person running it.

Remember

  • Credits pay for model work, tool calls, compute, Brain and orchestration
  • Each task shows its credit total and a breakdown
  • Smaller models, fewer tools and fresh tasks reduce spend
