Getting GPT to reply persistently and with type
GPT, and some other generative mannequin, tends to supply disparate solutions for a similar query, generally they’re only a bit totally different, generally very totally different and even contradictory.

Having management of what GPT solutions is technically known as finetuning; finetuning is about “taming the beast” and making it reply what you want in your explicit arrange. There are totally different approaches to finetuning, usually primarily based on the software program aspect: parameters…
We’ve approached the issue utilizing knowledge: can we make GPT to reply correctly to some questions? By correctly we imply in the precise tone and company type, with the precise content material and with out glitches/contradictions/hallucinations.
For this experiment, we’ve generated a dataset verticalized for the banking sector (retail banking, loans, wealth administration…) and customised for Buyer Assist.
We name this dataset hybrid as a result of it combines some great benefits of artificial textual content (low value, excessive scalability and pace, privateness…) with out the disadvantages (hallucination and bias primarily). It accommodates 30M tokens… and you may see a pattern… With this knowledge we finetuned GPT 3.5…
See SCREENSHOTS 4, 5 and 6
As you’ll be able to see within the screenshots, the conduct of GPT might be modified (finetuned) for particular functions, in our case Buyer Assist Banking.
When the questions used for testing are a part of the coaching knowledge, it’s much less stunning that the solutions are positively influenced by the coaching.
It’s a bit extra stunning when utilizing questions that the place not used within the coaching, just like the one we used “how a lot does it value to open an account for worldwide banking”.
As we will see, all of them:
- present right content material (in response to coaching)
- comply with the identical construction (firm coverage for Buyer Assist)
- they’re constant amongst them, eliminating the “disparateness” issue we noticed in GPT solutions
Conclusion: data-based finetuning can get us one of the best of two worlds:
- the creativity of the generative capabilities of GPT
- the accuracy and consistency of finetuning
