Why the edge:
- Agent interface, MiMo-V2.6-Flash-RL +25: BigBang-v1 60 (Chat template 20, the base's template in the repository.); MiMo-V2.6-Flash-RL 85 (Chat template 20, chat_template.jinja in the repository (3,868 characters), with a copy in tokenizer_config.json.)
- Documentation and upkeep, MiMo-V2.6-Flash-RL +13: BigBang-v1 46 (Model card 11 of 20, limitations, architecture and a cut-off are missing.); MiMo-V2.6-Flash-RL 59 (Model card 14, Intended use, the architecture, the parameters, the context and the languages (in the metadata) are on the card.)
- Risk, BigBang-v1 +10: BigBang-v1 55 (File safety 25, safetensors only and nothing from the repository runs.); MiMo-V2.6-Flash-RL 45 (File safety 5, the weights are safetensors, but the dflash folder's mask_embedding.pt is a pickle beside them (15).)
- Reach, MiMo-V2.6-Flash-RL +5: 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.); MiMo-V2.6-Flash-RL 65 (Memory 5, the smallest build at 4 bits or better is ggml-org's MXFP4 GGUF, 168.93 GB with its projector, and 168.93 GB × 1.2 = 202.7 GB, within 256 GB.)
