Add access to Meta LLaMa models

[mwolfson]

I would like to add access to these models next, but not sure which API resource is a good one to use. I've already added the APIs for the products I have access to (and I signed up for Anthropic which allows access to APIs with a pay-as-you-go plan, but not requiring a pro subscription).

Would love to add LLaMa (and other models) and want to figure out the best way to do this.
