Why the edge:
- Reach, MiniCPM5-2B +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.); MiniCPM5-2B 90 (Memory 30, OpenBMB's own MLX 4-bit build is 1.42 GB and its Q4_K_M GGUF 1.56 GB, about 2 GB with the fifth added.)
- Documentation and upkeep, MiniCPM5-2B +25: Inkling 2 Small 67 (Model card 17 of 20, everything but a dated knowledge cut-off.); MiniCPM5-2B 92 (Model card 17, everything but a knowledge cut-off.)
- Risk, Inkling 2 Small +10: Inkling 2 Small 65 (File safety 25, safetensors only and no repository code to run.); MiniCPM5-2B 55 (File safety 25, safetensors and GGUF only, and the documented way to load it runs no code from the repository.)
- Agent interface, Inkling 2 Small +10: Inkling 2 Small 85 (Chat template 20, a Jinja file in the repository.); MiniCPM5-2B 75 (Chat template 20, a Jinja file in the repository.)
