You can't expect a 1B model to perform as well as 7B or chatGPT, probably the best use case is speculative decoding or to use to fine tune for a specific use case.

What is "speculative decoding"?

[regularfry]

Speculative decoding is using a small model to quickly generate a sequence that every so often you pass through a larger model to check and correct. It can be much faster than just using the larger model, with tolerably close accuracy.

No, speculative decoding has exactly the same accuracy as the target model. It is mathematically identical to greedy decoding.

Is there a reference for this? I was wondering the same thing.

[qeternity]

Read the original whitepaper or go look at how any framework implements it.

You will see that tokens not predicted by greedy sampling of the target model are rejected. Ergo, they are mathematically identical.
