Last update on 2025-05-20

Llama2 70B is a large language model developed by Meta Llama, a company, featuring 70b parameters. It is released under the Llama 2 Acceptable Use Policy (LLAMA-2-AUP) and Llama 2 Community License Agreement (LLAMA-2-CLA). The model is part of the Llama2 series, which includes open-source language models ranging from 7B to 70B parameters, designed for diverse applications and research.

Description of Llama2 70B

Llama2 70B is a large language model with 70b parameters, part of the Llama2 series, which includes models ranging from 7 billion to 70 billion parameters. It features variations like Llama-2-Chat, optimized for dialogue interactions with enhanced helpfulness and safety. The model is trained on 2 trillion tokens of publicly available data and employs an optimized transformer architecture. It uses supervised fine-tuning (SFT) and reinforcement learning with human feedback (RLHF) to improve alignment with user expectations. The Llama 2 Acceptable Use Policy (LLAMA-2-AUP) and Llama 2 Community License Agreement (LLAMA-2-CLA) govern its usage, ensuring responsible deployment.

Parameters & Context Length of Llama2 70B

70b 4k

Llama2 70B has 70b parameters, placing it in the very large models category, which excel at complex tasks but require significant computational resources. Its 4k context length falls under short contexts, making it suitable for concise tasks but limiting its ability to handle extended texts. The high parameter count enables advanced reasoning and generation, while the moderate context length balances efficiency with practicality for many applications.
