Yeah this is the opposite, they did impressively well with fewer parameters.

In general larger models and more data has been an effective strategy for getting better performance but getting the right ratio is also important: https://www.deepmind.com/publications/an-empirical-analysis-...

+1, also this is a teacher model. The implications are huge here as AWS will likely spin this into an offering like they did with their other AI products. Building a model downstream of GPT-3 is difficult and usually yields suboptimal results; however 20b is small enough that it would be easy to finetune this on a smaller dataset for a specific task.

You could then distill that model and end up with something that’s a fraction of the size (6b parameters for example, just under 1/3, would fit on commercial GPUs like 3090s). There are some interesting examples of this with smaller models like BERT/BART or PEGASUS in Huggingface Transformer’s seq2seq distillation examples.
