Oh, good catch. I do use Sol in production, for cases where I need quite good results, but can't afford to run in production the highest tier model due to pricing (so it's like the highest tier model I can afford for that use-case).

To be more specific, this is for a support automation, where the model has to be quite accurate in following rules and generate responses, and Luna models or lower-tier models often make bad mistakes and generate wrong responses, so are not really usable for sending data directly to the user.
