Why the edge:
- Documentation and upkeep, Arete-27B +27: Arete-27B 63 (Model card 8, no limitations, context length, languages or cut-off.); Laguna M.1 36 (Model card 11 of 20, intended use, architecture, parameters and context are there, limitations, languages and a cut-off aren't.)
- Agent interface, Laguna M.1 +25: Arete-27B 60 (Chat template 20, a Jinja file in the repository.); Laguna M.1 85 (Chat template 20, a Jinja file in the repository.)
- Reach, Laguna M.1 +20: 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.); Laguna M.1 70 (Memory 5 of 30, the smallest 4-bit build is Poolside's 139.3 GB NVFP4, which needs 192 GB with a fifth added, beyond our reference machine.)
