Llama-2 and GPT series models: two different technical paths

Llama-2 and GPT series models are both large-scale language models, but there are significant differences in design philosophy, architectural details, training data, and application scenarios. Llama-2 is an open source project released by Meta and is easily accepted by the academic community and the developer community, while the GPT series is a mature closed-source commercial product developed by OpenAI. Llama-2 improves efficiency and effectiveness through a series of technological innovations, while the GPT series is known for its ability to support up to 26 languages.
