Why the edge:
- Risk, Darwin-36B-Opus +15: Darwin-36B-Opus 55 (File safety 25, safetensors and GGUF only with no code in the repository, so the card's trust_remote_code flag loads nothing extra.); LFM3-Audio-2B 40 (File safety 15, safetensors only, no .bin, .pt or .pth files (25).)
- Agent interface, LFM3-Audio-2B +15: Darwin-36B-Opus 70 (Chat template 20, Qwen3.6's Jinja template in the repository.); LFM3-Audio-2B 85 (Chat template 20, chat_template.jinja in the repository (9,328 characters), with roles, audio, tools, deferred tools and tool results.)
- Documentation and upkeep, Darwin-36B-Opus +9: Darwin-36B-Opus 61 (Model card 11, it covers architecture, parameters, context and languages but not intended use, limitations or a knowledge cut-off.); LFM3-Audio-2B 52 (Model card 17, Intended use (local agents, tool calling, structured outputs, fine-tuning), limitations (not recommended for agentic coding or complex multi-step…)
