Why the edge:
- Reach, MiniCPM-o 4.5 +50: Inkling 2 Small 40 (Memory 0 of 30, the smallest build is Thinking Machines' NVFP4 checkpoint at 393.5 GB, about 472 GB with a fifth added, above the 256 GB line.); MiniCPM-o 4.5 90 (Memory 30, OpenBMB's 4-bit GGUF with its vision file is 5.9 GB, about 7 GB with a fifth added.)
- Agent interface, Inkling 2 Small +50: Inkling 2 Small 85 (Chat template 20, a Jinja file in the repository.); MiniCPM-o 4.5 35 (Chat template 20, a Jinja template in the tokenizer config.)
- Risk, Inkling 2 Small +25: Inkling 2 Small 65 (File safety 25, safetensors only and no repository code to run.); MiniCPM-o 4.5 40 (File safety 5 of 25, two pickle files sit in the speech stage and the documented load runs repository code.)
