Llama 3.1 405B

Llama 3.1 405B is the largest and most capable model in the Llama family, representing Meta's flagship open-source release. It competes directly with leading proprietary models on benchmarks spanning reasoning, coding, math, and multilingual understanding. Running this model locally requires enterprise-grade hardware with multiple high-end GPUs. However, for users with the necessary infrastructure, it provides state-of-the-art open-source performance without any API dependencies.
