Notion says its new automatic model picker delivers results similar to its top AI models at about 90% lower average cost, according to the company’s October 19 announcement. That one number tells you something important about where AI pricing is going. The same request can cost you very different amounts depending on which model handles it. Welcome to AI credits. If that phrase makes your eyes glaze over, this guide is for you.
What an AI credit actually is
An AI credit is a unit of AI usage that a software company sells you, a bit like tokens at an arcade. Each time the AI does something for you (writes a draft, summarizes a document, runs an agent), it uses up some credits. Bigger or harder tasks use more.
Behind the scenes, AI companies pay for computing power every time a model answers. Simple tasks on small, fast models are cheap. Long tasks on the most powerful models are expensive. Credits are how software companies pass that varying cost on to you without billing you a few cents at a time.
Why this suddenly matters for a solo business
For the past couple of years, most AI features came bundled into a flat monthly price. You paid for the plan and used the AI as much as you liked, within fair limits. That is changing. More tools now include a monthly allowance and charge for extra usage, or ask admins to buy top-ups.
Notion is a clear example. Its new system, live now for new customers and arriving for existing customers on November 2, puts all AI use under one credit balance. Business and Enterprise seats include two monthly pools: one for when Notion picks the model, and a smaller one for when you pick the model yourself or run custom agents. Microsoft is heading the same way; its Copilot release notes now refer to tracking “credit usage” for business customers.
The practical effect: two people on the same plan can have very different AI bills, depending on how they use it.
The three things that make a task “expensive”
You do not need to understand the technology to spend credits wisely. Just watch three things:
- Which model you choose. The most powerful models cost the most. If a tool offers “Auto,” it usually picks a cheaper model for simple work.
- How much you feed it. Asking AI to read a 60-page document costs more than asking about one paragraph.
- How long it works. Agents (AI that takes many steps on its own) can run for minutes or hours. Every step uses credits.
A simple budgeting habit for credit-based AI
You do not need a spreadsheet. Try this for one month:
Week 1: just watch
Use your tools as normal, then look at the usage or billing page at the end of the week. Most tools that use credits show a running balance. Note roughly what share of your monthly allowance you used.
Week 2: default to Auto
Wherever a tool offers automatic model selection, use it. Only switch to a premium model for work that clearly needs it, like a tricky client proposal or a contract summary. In Notion’s case, picking a model yourself draws from the smaller pool, so Auto stretches your allowance much further.
Week 3: trim the inputs
Instead of pasting a whole document, paste the section you need. Instead of “read my entire inbox,” ask about one client thread. Smaller inputs mean fewer credits and, often, better answers.
Week 4: decide on agents
If you run agents, list each one and what it saves you. An agent that saves two hours a week is worth its credits. One you set up and forgot about is quietly spending your allowance.
Credits versus flat plans: which is better for you?
Neither is automatically better. Credit systems tend to suit light or uneven users, because you pay closer to what you actually use. Flat plans suit heavy, steady users, because the price stays put no matter how busy you get. If you use AI a little most weeks and a lot in a busy season, credits are often fairer. If you lean on AI all day, every day, watch for “unlimited” or high-allowance plans and compare the total monthly cost, not just the headline price.
Money-saving moves worth knowing
- Reuse subscriptions you already pay for. Notion now lets you connect a ChatGPT Plus, Pro, or Go plan to your personal Notion agent, and says that usage does not draw down your Notion credits.
- Free tiers are shrinking, so test before you upgrade. We covered one example in 7 quick moves before you pay for Google AI Plus.
- Do not pay twice for the same job. If your automation tool, writing app, and CRM all add AI, pick one place for each task. Our automation tool comparison shows how usage limits differ between Zapier, Make, and n8n.
- Set alerts where you can. Notion says spending limits and usage alerts are coming to its admin tools. Turn on any alerts your tools offer.
Your first step, today
Open the one AI tool you use most and find its usage or billing page. That is it. Knowing where the meter lives is the foundation of everything else.

Credits can feel like one more thing to manage. In practice, a few habits (use Auto, trim inputs, review agents monthly) keep most solo owners comfortably inside their allowance. Which of your AI tools has switched to credits so far?
