Ornith-1.5-9B scores 61 (C) on agent readiness against Cola2's 33.9 (F), and leads in 3 of 4 scored categories. Cola2 leads on documentation and upkeep. Both do open-weight models you run yourself.

- Cola2: F 33.9, rank #160 of 160 open-weight models · https://www.anchorterminal.com/tools/cola2.min.md
- Ornith-1.5-9B: C 61, rank #51 of 160 open-weight models · https://www.anchorterminal.com/tools/ornith-1-5-9b.min.md
- Cola2, good for Researchers working on latent or diffusion language models who want a checkpoint to study Ahead on Documentation and upkeep, 58 against 31.
- Ornith-1.5-9B, good for Local coding and terminal agents on a laptop or a single consumer GPU, where a clear licence file and an answering publisher aren't required Ahead on Reach, 95 against 25; Risk, 50 against 40; Agent interface, 85 against 20.

Why the edge:
- Reach, Ornith-1.5-9B +70: Cola2 25 (Memory 15, the only build is the F32 safetensors set, 35.07 GB, and 35.07 GB × 1.2 = 42.1 GB, within 64 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 +65: Cola2 20 (Chat template 20, A chat template in tokenizer_config.json (4,116 characters), which came with the Qwen3 tokenizer.); Ornith-1.5-9B 85 (Chat template 20, a Jinja file in the repository.)
- Documentation and upkeep, Cola2 +27: Cola2 58 (Model card 8, Intended use and limitations (the out-of-scope list, and the unconverged latent model) and the architecture are on the card and the GitHub model c…); 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.)
- Risk, Ornith-1.5-9B +10: Cola2 40 (File safety 15, safetensors only, no .bin, .pt or .pth files (25).); Ornith-1.5-9B 50 (File safety 25, safetensors and GGUF only and no Python in any of Ornith's repositories, so the card's --trust-remote-code flag loads nothing from the repositor…)
