Why the edge:
- Reach, Ornith-1.5-9B +55: Kimi K3.1 Pro 40 (Memory 0, the only build is Moonshot's 1,561 GB MXFP4 release, far above 256 GB.); Ornith-1.5-9B 95 (Memory 30, since Ornith's own MLX 4-bit build is 5.0 GB and needs about 6.0 GB with the fifth added, and its Q4_K_M GGUF and Ollama's build fit 16 GB too.)
- Agent interface, Ornith-1.5-9B +20: Kimi K3.1 Pro 65 (Chat template 10, the format is only code to run.); Ornith-1.5-9B 85 (Chat template 20, a Jinja file in the repository.)
- Documentation and upkeep, Kimi K3.1 Pro +20: Kimi K3.1 Pro 51 (Model card 11, no limitations, languages or cut-off.); Ornith-1.5-9B 31 (Model card 11, it covers intended use, architecture, parameters and context but not limitations, languages or a knowledge cut-off.)
