With GPT-4 LJ costing around $6,000 to train and Dolly 2.0 featuring a 12 billion parameter model fine-tuned on 15,000 human-generated prompts, both offer exciting opportunities for developers. These models can be economically trained and deployed for proprietary use cases, making it an exhilarating time for data scientists.
