Theoretically this is an even better size, as it would fit on a 20GB-24GB GPU with more relaxed quantization and much longer context.
Metrics are slightly below 13B, but the theory is that the higher parameter count is more amenable to finetuning. If you search for 22B on huggingface, you can see that frankenllama experiments are ongoing:
Meta says later on that they aren't releasing it and give no explanation. I wonder why given how incredible it seems to be.
If you're using it commercially you're probably deploying it on a server where you're not limited by the 24GB and you can just run llama 2 70b.
The majority of people who want to run it locally on 24GB either want roleplay (so non commercial) or code (you have codellama)
