Equation 1 · Part 1 · Context Window Size Versus What a Frontier Model Can Actually Recall From It
Symbol W
What this part means
the context window a vendor documents for a given model, a fixed engineering figure set by attention implementation, position encoding, and what the serving stack supports.
Its job in the formula
W is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it
Formalise the distinction the whole comparison rests on: let W be the context window a vendor documents for a given model, a fixed engineering figure set by attention implementation, position encoding, and what the serving stack supports.
The passage around this formula
Put the documentation and the independent benchmarks side by side and a pattern emerges that is more informative than any single score. Formalise the distinction the whole comparison rests on: let W be the context window a vendor documents for a given model, a fixed engineering figure set by attention implementation, position encoding, and what the serving stack supports. Let S(n) be some benchmark’s measured accuracy at input length n W , and the same benchmark’s accuracy at a short reference length. For a chosen retention threshold , define the effective context length as

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
