- Substitute for Money: A metal or plastic disc used instead of cash for a bus, train, or arcade game.
- Digital or Crypto Unit: A unit of value on a blockchain or a digital pass that lets you log into a secure computer system.
- AI Text Unit: A piece of a word that an artificial intelligence model reads and writes. One token is about 4 characters or three-quarters of an English word.
- Minimal Effort: Doing something just to say you did it. Example: A token effor

1. AI and Tech Tokens
- Definition: Small pieces of data or characters used by computer code and AI.
- Function: AI systems break human words down into chunks to read and process them.
- Example: The phrase “eating apples” might be split by an AI into two tokens: “eating” and ” apples”.
2. Crypto Tokens
- Definition: Digital assets built on top of an existing blockchain network.
- Function: They represent a specific project’s currency, utility, or digital asset ownership.
- Example: Basic Attention Token (BAT) or various meme coins that run on the Ethereum network.
3. General English Definitions
- Definition: A physical object or small action that stands for an idea, feeling, or currency.
- Function: It acts as a symbol of appreciation, a voucher for goods, or a substitute for cash.
- Example: Giving someone a voucher for a free coffee, or handing an arcade token to a machine.

An AI token limit is the maximum number of tokens (words and word pieces) a model can process in a single conversation. This includes both your prompt and the AI’s generated response. [1, 2, 3]
Think of it like a computer’s short-term memory capacity. [4, 5]
How Token Limits Work
- The Memory Box: An AI has a fixed “context window” size.
- The Shared Pool: Your prompt and the AI’s answer share this single pool of tokens.
- The Cut-off: If your prompt takes up 90% of the limit, the AI only has 10% left to answer. [6, 7]
The Most Important Points to Know
- The “Goldfish” Effect: Once a conversation crosses the token limit, the AI forgets the very earliest messages.
- Hidden Math: System instructions, chat history, and uploaded files all eat into your token limit before you even type.
- Cost Factor: If you use a developer API, you are billed directly by the total number of tokens processed.
- Efficiency Matters: Writing highly concise prompts leaves more room for the AI to give a complete, detailed answer. [8, 9, 10, 11, 12]

Pay-as-you-go (PAYG) is a payment model where you only pay for a product or service as you use it, rather than paying a large amount upfront or signing a long-term contract. Depending on the industry, it can mean adding money to an account beforehand (prepaid) or being billed afterward based on your exact usage (consumption-based). [1, 2, 3]
- No long contracts: You are not locked into a subscription.
- No upfront waste: You never pay for unconsumed data or time.
- Full financial control: You can scale spending up or down instantly.
- Debt avoidance: It relies on current cash rather than credit cards.

| Industry | How It Works |
|---|---|
| Telecommunications | Prepaid SIM cards where you buy credit for talk, text, and data in advance. |
| Cloud Computing & Tech | SaaS and storage platforms (like Amazon Web Services) that charge strictly per gigabyte or processing hour used. |
| Utilities | Prepaid energy meters where you top up an account before using electricity or gas. |
| Transportation | Toll roads and transit cards (like London’s Oyster card) that deduct cash only when you make a trip. |
| Government Finance | A budgeting policy where government projects are funded via current tax revenues instead of taking on public debt. |
