How this RAM-tier order works

This contextual order uses LocalClaw catalogue quality, reasoning, coding and speed fields plus freshness and RAM fit. It is not the homepage LocalClaw score, not a standardized third-party benchmark and never includes community stars. Catalogue summaries may repeat upstream claims; verify them at the linked model repository.
