At the time of writing, AWS Inferentia2 does not support dynamic shapes for inference, which means that we need to specify our sequence length and batch size ahead of time. 1 70B. LLaMA 2 represents the next iteration of LLaMA and comes with a commercially-permissive license. py script: Llama 2 Parameters. From Table 4, we can see that the performance of LLAMA 2-7B and 13B on LAMA is identical , and even increasing the model size to 70B results in only a slight improvement (58. 3. Model Architecture. If not, A100, A6000, A6000-Ada or A40 should be good enough. 28 GB: 31. Input: Models input text only. Token counts refer to pretraining data only.

Variations Code Llama comes in four model sizes, and three variants: Code Llama: base models designed for general code synthesis and understanding; Code Llama - Python: designed specifically for Python; Code Llama - Instruct: for instruction following and safer deployment; All variants are available in sizes of 7B, 13B, 34B, and 70B parameters. I personally prefer Llama-3. Example using curl: Although one might think Llama 2’s size makes it less accurate than GPTs, the 5-shot MMLU benchmark shows that Meta’s model performs nearly on par with GPT-3. This indicates that only increasing model size is difficult to improve the model’s ability to remember and understand knowledge present in the training You're only looking at 1 dimension to scaling (model size), and ignoring the other: dataset size (number of training tokens). Model Dates Llama 2 was trained between January 2023 and At the heart of any system designed to run Llama 2 or Llama 3. Bigger models - 70B -- use Grouped-Query Attention (GQA) for improved inference scalability. 2. Llama-2–70b that has 70 billions parameters. gguf: Q2_K: 2: 29.
