The new open-source AI model from China, Yi, has double the capacity of ChatGPT and can handle up to 200,000 tokens of context. The Yi models outperform larger models like LLaMA2-70B and Falcon-180B and quickly became the second most popular open-source model on Hugging Face. Users can run Yi locally, offering greater control, customization, and independence from external servers, making it a promising alternative for AI applications.
