Why the edge:
- Documentation and upkeep, Arete-27B +17: Arete-27B 63 (Model card 8, no limitations, context length, languages or cut-off.); BigBang-v1 46 (Model card 11 of 20, limitations, architecture and a cut-off are missing.)
- Reach, BigBang-v1 +10: Arete-27B 50 (Memory 10, the only build from Nous Research is the 54.7 GB BF16 release, which needs about 66 GB and fits the reference machine.); BigBang-v1 60 (Memory 10 of 30, the only build from the publisher is BF16 at 71.9 GB, 86.3 GB with a fifth added, which fits the reference machine but not 64 GB.)
