GPT3.5 fine tuning is here

The Future is Here: How Fine-Tuning GPT-3.5 Turbo Will Change the Game for Developers

Hi everyone! Today I want to talk to you about something new that is shaking the world of technology: fine-tuning for GPT-3.5 Turbo is finally available! And that's not all, as fine-tuning for GPT-4 will arrive this fall. But let's go in order, there's meat on the fire here!

What is Fine Tuning?

For those who don't know, fine-tuning is a technique that allows you to customize artificial intelligence models to make them better perform in specific contexts. In practice, it is as if we could "educate" the model to do exactly what we want, and do it well.

Why is it a Big Deal?

First of all, preliminary tests have shown that a fine-tuned version of GPT-3.5 Turbo can match, or even exceed, the basic capabilities of GPT-4 in certain specific tasks. So, imagine having an AI that you can mold like clay into a real ace in your field. And the great thing is that the data you send for fine-tuning is yours and is not used by OpenAI or other organizations to train other models.

Use Cases

Fine-tuning can be used to:

  • Improve “drivability”: For example, if you want the model to always respond in German, you can do so.
  • Reliable response formatting: If you need your model to generate code or API calls in a specific format, fine-tuning is your secret weapon.
  • Tone customization: If you have a brand with a distinctive voice, you can use fine-tuning to make the model align with your style.

How does it work?

  1. Prepare the data: Train the model with specific examples.
  2. Upload files: Use the OpenAI API to upload your data.
  3. Create a fine-tuning job: Once again, an OpenAI API comes to the rescue.
  4. Use the fine-tuned model: Once the process is complete, the model is ready to be used in production.

Safety and Costs

OpenAI has put security measures in place to ensure fine-tuning complies with their standards. As for costs, they are divided into training costs and usage costs, which vary based on the number of tokens used.


Fine-tuning is a revolution, friends. And if you are a developer or entrepreneur in the digital world, this is one of the most powerful weapons you can have in your arsenal. So get ready, because the future is already here!

And you, what do you think of fine-tuning? Let me know in the comments!
