Compare 2-25 AI models side-by-side showing FNI scores, factor breakdown (Semantic, Authority, Popularity, Recency, Quality), specs (params, VRAM, context length), and license. Read-only, no side effects. Cold upper-range multi-paper requests may return a transient 503 (retry after the indicated delay). Use this when the user wants to decide between specific known models; use free2aitools_select_model to discover models first, then compare the top candidates.
