Reply to comment by MysteryInc152 in [D] Are modern generative AI models on a path to significantly improved truthfulness? by buggaby

Thanks for that note. This sounds like, basically, 2 data sets are needed for this process. One with general responses and language, and one with high-accuracy contextual knowledge.

According to OpenAI

So maybe we need even more work to keep these truthful.

From the paper,

>While larger models were less truthful, they were more informative. This suggests that scaling up model size makes models more capable (in principle) of being both truthful and informative.

I suppose that was what i was getting at.

The only hold up with the original paper is that none of the models evaluated were instruct aligned.

But you can see the performance of more models here

You can see the text Davinci models are way more truthful than similar sized or even larger models. And the davinci models are more truthful than the smaller aligned Anthropic model.

Yup. Decided to go over it properly.

If you compare all the instruct tuned models on there. Greater size equals Greater truthfulness. From Ada to Babbage to Curie to Claude to Davinci-002/003.

So it does seem once again that scale will be in part the issue

Informative. Thanks. I'm a complexity scientist with training in some ML approaches, but not in transformers or other RL approaches. I'll review this (though not as fast as a LLM can...)

How do you find the model size? All those you listed appear to be based on GPT-3 or 3.5 which, according to my searching, are both 175B parameters. It looks to me like they are different only in the kind and amount of fine-tuning. What am I missing?
