Symbol c
c is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.
How to interpret it
Its accuracy depends on the assumptions and range of use described in the article.
What the article says around this equation
Every published leaderboard number implicitly assumes c 0 . The methods above show that assumption is not something the field can currently verify for a given open-weight release, only something it can occasionally catch violated in specific, published cases — which is a different and much weaker guarantee than a general bound on c .
