Side-by-side comparison of Grok-2 (xAI · USA) and Llama 3.1 405B (Meta · USA) for self-hosted deployment of the open-weight model. Grok-2 is rated conditional; Llama 3.1 405B is conditional. They part ways on licence: Grok-2 is "Grok 2 Community", Llama 3.1 405B is "Llama community".
| Field | ||
|---|---|---|
| Summary | ||
| Verdict | Conditional xAI's first open-weights release. Commercial use allowed under the Grok 2 Community License with xAI's Acceptable Use Policy. Notable restriction: weights cannot be used to train other models (distillation ban). 500GB model, needs 8 GPUs with 40GB+. | Conditional Frontier-class 405B open model. Self-hosting requires serious compute (8×H100 minimum at FP8). Same Llama community licence caveats as the rest of the family. |
