Train context only to gpt-3.5-turbo (fine-tuning)

I need to train my context only to gpt-3.5-turbo, if I ask question through chat completion, it should answer from the learned context. can I do this? if so someone please give an example train data and code

You can read all about fine-tuning on the API, which not only costs for the training, but then your use of the model is significantly higher (but you may not need to have as much data as input in order to receive some degree of success on new behaviors.

https://platform.openai.com/docs/guides/fine-tuning

The data you need to prepare is extensive and laborious: a large set of examples showing the AI the type of input the user will be making, and how the AI would respond to each, then hopefully picking up some knowledge and skill on similar questions asked by real users.

You can see this is not for your own personal use, but rather for developing products. If you already know all the answers the AI should be providing, you don’t actually need an AI to answer them.
