Why the edge:
- Documentation and upkeep, Arete-27B +35: Arete-27B 63 (Model card 8, no limitations, context length, languages or cut-off.); InternVL3.5-GPT-OSS-20B-A4B-Preview 28 (Model card 8 of 20, the family card misses limitations, context, languages and a cut-off.)
- Reach, InternVL3.5-GPT-OSS-20B-A4B-Preview +15: 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.); InternVL3.5-GPT-OSS-20B-A4B-Preview 65 (Memory 15 of 30, the only builds are BF16 at 42.5 GB by the repository's safetensors index, or 51 GB with a fifth added, which fits 64 GB.)
- Agent interface, Arete-27B +15: Arete-27B 60 (Chat template 20, a Jinja file in the repository.); InternVL3.5-GPT-OSS-20B-A4B-Preview 45 (Chat template 20, a Jinja file in the repository, though it doesn't match the tokenizer.)
