What is the right way for a company to use Transformers library for commercial use?

Hello, I would like to get some guidance on using Transformers library for commercial use.

I work for a small company and fine-tuned Bert for text classification. I used Trainer() on our internal data and the classification pipeline will be called to get a class. Now we want to add the fine-tuned model predictions as a step in the service that we sell.

Do we have to buy a Licence to use it in production?

I see there is a Pricing section. Now I am on a free community plan as a developer. Do we have to buy organisation subscription in our case?

Thank you!
