This is a good question. Personally, I think it is a better way for most companies to directly use the API of OpenAI, which is currently the best in terms of ease of use and ability in the general field. I think there are only a few types that need to retrain the model themselves. 1. Researchers who are very cutting-edge and have sufficient funds. 2. Large companies that require ultra large amounts of calls or have strict confidentiality requirements. 3. Application scenarios in very specific fields, such as chemical molecules, may require more domain specific pretraining.
