| Summary | ||
| Verdict | 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. | Conditional NVIDIA's Llama 3.1 fine-tune with custom RLHF. Inherits Llama 3.1 Community License terms. Strong conversational quality; useful default when you want Llama behaviour with NVIDIA's alignment. |
