What does the human evaluation study suggest about the 405B model's responses compared to other models?
-The human evaluation study suggests that while the 405B model's responses are comparable to the original GPT 4 and CLONT 3.5 SONNET, GPT 4 O is preferred by humans more than the 405B model.
What is the LLAMA system introduced with the LLAMA 3.1 release?
-The LLAMA system is an oral system that can orchestrate several components, including calling external tools. It is designed to provide developers with a broader system that offers flexibility to design and create custom offerings.
What are the VRAM requirements for running the different LLAMA models?
-The VRAM requirements vary based on the model size and precision. For example, running the 8 billion model in 16-bit floating precision requires 16 gigabytes of VRAM, while the 70 billion model needs 140 gigabytes, and the 405 billion model requires 810 gigabytes at the same precision. However, running the 405B model in 4-bit precision would only need 203 gigabytes of VRAM.
