Why the edge:
- Agent interface, gpt-oss-20b +70: Cola2 20 (Chat template 20, A chat template in tokenizer_config.json (4,116 characters), which came with the Qwen3 tokenizer.); gpt-oss-20b 90 (The chat template earns 20, a Jinja file in the repository.)
- Reach, gpt-oss-20b +65: 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.); gpt-oss-20b 90 (Memory earns 25, since OpenAI's own MXFP4 build is 13.76 GB and a fifth on top is 16.5 GB, just past the 16 GB band, and Ollama's 14 GB build lands in the same…)
- Risk, gpt-oss-20b +45: Cola2 40 (File safety 15, safetensors only, no .bin, .pt or .pth files (25).); gpt-oss-20b 85 (File safety earns 25, since the weights are safetensors and metal/model.bin is OpenAI's own raw Metal format rather than pickle, and nothing in the repository r…)
- Documentation and upkeep, Cola2 +16: 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…); gpt-oss-20b 42 (The model card earns 17, covering six of the seven points and missing a statement of supported languages.)
