What "free" usually contains
Every major assistant has a free tier, and they are more generous than most people expect. A typical one gives you:
- A limited number of messages on the strong model, then an automatic switch to a smaller one.
- Smaller limits on file size, uploads per day, and images.
- Web search, sometimes, and often fewer searches.
- Little or no memory across conversations.
- Your conversations used to improve the model, unless you change a setting or live somewhere the law says otherwise.
That is enough for a great deal of real work. A student writing essays, a shopkeeper drafting supplier emails, a nurse checking her English phrasing — none of these people need to pay anything.
Six traps
1. The silent downgrade. You use up your allowance of the strong model, the product moves you to a smaller one, and the only sign is that answers get shallower. People conclude "it got worse this week." It did not. You did. Look for the model name in the interface before you form an opinion.
2. Judging a company by its free tier. The free tier is the cheapest model the company is willing to serve at scale. It is not what the product can do. If you are deciding whether to pay, that decision cannot be made on free-tier output alone.
3. Rolling windows, not calendar days. Limits usually reset on a rolling window — five hours from your first message, not at midnight. Plan the heavy task for the start of a window.
4. Free trials with a card attached. A one-month trial that renews at full price is a normal business practice and a real cost if you forget. Set a reminder for two days before it renews, the day you sign up.
5. Free API credits that expire. Several providers hand new developers credits worth $5 to $300. They expire, often in 30 to 90 days, and they are not refundable. Fine, as long as you know.
6. Wrappers charging for something free. App stores and browser extension stores are full of apps that charge a monthly fee to pass your question to a model you could have used at no cost. This trap catches the most people in markets where the official apps are hard to reach or pay for. Before paying anyone, check whose model is underneath.
Free things genuinely worth knowing about
- Developer free tiers. Google's AI Studio has historically offered a free quota on its API that is generous enough for small projects. Others offer free credits. These come with the usual condition: free usually means your data can be used to improve the service.
- Open models on your own machine. No account, no limit, no message cap, and nothing leaves your laptop. Two lessons from now.
- Cheap hosted open models. Several companies serve Llama, Qwen, Mistral and DeepSeek at a fraction of frontier prices, some with a free tier.
- School and university access. Many institutions have licences their students do not know about. Ask.
Getting a lot from free
Run two or three free tiers side by side. When one caps you, move to the next. Save your strongest-model messages for the task that needs them — the hard analysis, not the quick rewrite. Batch small questions into one message rather than spending five turns on them.
A person who is deliberate about this gets most of the value of a paid plan for nothing. The next lesson is about the cases where that stops being true.
