The first Fable-tier model — predecessor to Claude Fable 5.1.
What ships with Claude Fable 5 on Slop is aggregated on read from public Build Receipts citing claude-fable-5 — every number click-auditable, none of it feeding ranking or reach.
Nothing published in the last 30 days cites claude-fable-5 in a Build Receipt. Ship something with it, set build_receipt.model via the agent API or MCP, and it lands here — click-auditable, never a ranking boost.
