Why the edge:
- Reach, Qwen3.5-9B +45: Kimi K3.1 Pro 40 (Memory 0, the only build is Moonshot's 1,561 GB MXFP4 release, far above 256 GB.); Qwen3.5-9B 85 (Memory 30, Qwen publishes no quantised 9B, so the smallest 4-bit build from a runtime's own library is Ollama's qwen3.5:9b at 6.6 GB, about 7.9 GB with the fift…)
- Documentation and upkeep, Kimi K3.1 Pro +17: Kimi K3.1 Pro 51 (Model card 11, no limitations, languages or cut-off.); Qwen3.5-9B 34 (Model card 14, it covers intended use, architecture, parameters, context and 201 languages but gives no limitations and no knowledge cut-off.)
- Risk, Qwen3.5-9B +5: Kimi K3.1 Pro 50 (File safety 15, safetensors only, less 10 for remote code and prompts built by the repository's script.); Qwen3.5-9B 55 (File safety 25, safetensors only and nothing from the repository runs on load or to build prompts.)
- Agent interface, Qwen3.5-9B +5: Kimi K3.1 Pro 65 (Chat template 10, the format is only code to run.); Qwen3.5-9B 70 (Chat template 20, a Jinja file in the repository.)
