The simplest way to do this is to look for AI sites that allow you to use a premium model as a trial.
Example is Google Gemini, or Suno.
With Google Gemini, you can have up to 5 messages with Gemini 2.5 pro per day, which considering Gemini is able to read up to 1
milion tokens (a lot of words), you can write long and long and long messages to consume as much server resource as you can, all within 5 messages.
As you can see, i dont have Google AI pro, but i can still chat with Gemini 2.5 pro up to 5 messages.
Same thing with Suno AI, they allow you to generate two songs, one minute each, as a preview of their latest audio model. you can generate 5 songs per day, which makes 10 minutes of premium ai music per day for absolute free, consuming server resources and company money without giving them anything.
There is another way:
using APIs.
For example, ChatGPT, aswell as Gemini, allow you to use their API for a little bit, for free, allowing you to use their premium models for a little bit.
Although this require you to be a developer, but i will write a script and a simple tutorial for anyone to do this in the future.
[NOVEMBER 2025 UPDATE]
Speaking of APIs, if you go to:
You can use premium Gemini Models for absolutely free, almost unlimited. It's basically a free way to have Google AI Pro/Ultra plans, but without giving them any money.
They lose on resources and budget.
And its not even illegal.
[DECEMBER 2025 UPDATE]
Sam Altman, CEO of OpenAI, seems to be victim of this basic method, since they launched code red for their AI model ChatGPT. Seems like the company is losing a lot on money, while having their model be dumber. A video that explains this well is linked below, although you can look up on internet any news article related to this event.
