Summary — verify against the official license text: https://www.llama.com/llama3/license/
Use, reproduce, distribute, copy and modify the Llama 3 materials, including commercially, subject to the Acceptable Use Policy, a "Built with Meta Llama 3" display, a separate license above 700 million monthly active users, and a ban on using the materials or outputs to improve other large language models.
| Use | Answer | Why |
|---|---|---|
| commercial_use | Yes | Permitted, with duties: attribution, license_notice, acceptable_use_policy, model_name_prefix, user_threshold. |
| model_training | Needs human review | You may fine-tune Llama 3 itself (a derivative must be named starting with "Llama 3"), but section 1.b.v forbids using the Llama materials or any output from them to improve any other large language model. A reviewer should confirm which side of that line your training falls on. |
