Use case

Designed for multi-document reading, synthesis, and staying coherent across larger contexts.

Sources to include

All public sources can include official company results while independent results catch up.

Access model

Primary filters

Current scoring recipecoverage, recency, and included sources

This preset weights long context, document understanding, reasoning math science with a 50% coverage floor and a 180-day recency window. Official company results can contribute when they are clearly labeled. Copied, historical, and demo data stay out unless you explicitly allow them.

Evidence & limits

Read the argument before you commit

Why these options made the listtop reasons behind the current answer

Current shortlist: Claude Fable 5, Claude Opus 4.8, Claude Opus 4.7, and GPT-5.5.
Claude Fable 5 is the strongest exact-match option still visible.
Claude Fable 5 currently leads the fit score at 100.0, but the evidence is still too mixed for a single headline winner.

What to pressure testwhere the current answer is still fragile

No single winner: The current public evidence is only strong enough to support a shortlist, not one winner.
Strongest alternative · Claude Opus 4.8: Claude Opus 4.8 is strongest on Reasoning / math / science and Long context for this preset.
Evidence risk: The verified evidence is decent, but too much of it is aging to treat this as a clean current winner.

What would flip the answerthe assumptions the result rests on

If you tighten benchmark spread: Claude Fable 5 still holds if you care more about aligned evidence than upside.
If you tighten recency: The winner becomes less stable quickly because the last-updated score is only 68 in the visible source data.
If you require open-weight: No open-weight model currently clears the same evidence floor.
If cost and speed matter more: No clearly cheaper alternative currently clears the same evidence floor.

Why this is not a clean winlimitations to keep in mind

The current evidence supports a shortlist, not a single winner.
Claude Opus 4.8 remains close enough that a different scoring recipe can still flip the public answer.
