Why the edge:
- Reach, Qwopus3.8-27B-Flash-V2 +50: LongCat-2.5 35 (Memory 0, the smallest build is Meituan's W4A4 repository, 1,336 GB, and 1,336 GB × 1.2 = 1,603 GB, far above 256 GB.); Qwopus3.8-27B-Flash-V2 85 (Memory 25 of 30, Jackrong's IQ4_XS GGUF is 15.4 GB, about 18.5 GB with a fifth added, which fits 24 GB.)
- Agent interface, LongCat-2.5 +15: LongCat-2.5 75 (Chat template 20, chat_template.jinja in the repository (11,823 characters), with a copy in tokenizer_config.json.); Qwopus3.8-27B-Flash-V2 60 (Chat template 20, a Jinja file in the repository.)
- Risk, LongCat-2.5 +10: LongCat-2.5 60 (File safety 25, safetensors only, no .bin, .pt or .pth files and no Python in the repository.); Qwopus3.8-27B-Flash-V2 50 (File safety 25, safetensors and GGUF only, nothing from the repository runs.)
- Documentation and upkeep, Qwopus3.8-27B-Flash-V2 +5: LongCat-2.5 46 (Model card 11, Intended use, limitations (the usage considerations), the architecture and the parameter counts are on the card.); Qwopus3.8-27B-Flash-V2 51 (Model card 11 of 20, missing architecture, context and a cut-off.)
