Claude Fable 5: the $10/$50 long-horizon Anthropic SKU

Fable 5 is not Sonnet with extra adjectives. It is the expensive long-horizon row. Read SWE-bench and output price together.

Frequently Asked Questions

Which is better overall, Claude Fable 5 or Yi-Large?: Claude Fable 5 has the higher preference Elo in our latest snapshot (1,616). “Better” still depends on coding, price, and latency — see the table.
Which is better at coding, Claude Fable 5 or Yi-Large?: Claude Fable 5 leads SWE-bench at 80% vs 53.8%. SWE-bench is one harness, not your repo.
Which is cheaper to run in production?: Yi-Large output tokens are $0.3/1M versus $50/1M. Input prices and retry rates still move the real bill.
Which is faster, Claude Fable 5 or Yi-Large?: Yi-Large has the lower time-to-first-token (220 ms vs 340 ms). Tokens/sec is a separate column if you care about long completions.
Which has the larger context window?: Claude Fable 5 accepts 1M tokens versus 33k.
Can I self-host either model?: Neither model is marked open-weights here. You are comparing hosted APIs.
Are these scores from CompareLLM’s own evals?: No. V1 aggregates public leaderboards (and optional first-party latency pings). Each cell names its source and date. Read /methodology.
What does preference Elo mean on this page?: Preference Elo is a crowd vote from LMArena / Arena. People see two hidden answers and pick the one they like more. The model that wins more often gets a higher Elo. That means people preferred it — not that it passed a school test. It is not SWE-bench, not accuracy, and not a number we invent. Claude Fable 5 and Yi-Large Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
