Odysseus only supports llama.cpp on Windows (vLLM/SGLang are explicitly blocked). llama.cpp requires GGUF, so AWQ/GPTQ/FP8 safetensors models without a GGUF alternate should not be recommended in the Cookbook on Windows hosts. Changes: - hardware.py: add 'platform': 'windows' to _detect_windows() so downstream logic can identify Windows hosts. - fit.py: include is_windows in the existing GGUF-only filter alongside apple_silicon and consumer_amd. - tests: add test_hwfit_windows.py with regression tests. Fixes #122, #614 (root cause: unservable models recommended).
