Can the model retain and reason over evidence spread across a very long input?

Long-context retrieval and reasoning, not context-window size alone. Higher is better. The value is the percentage reported in this lab's table.

Harness, tools, prompts, attempt count, and benchmark version can materially change the result. Compare within one reporting context.

Meta's general-capability figure; the report labels this as a 1M context window result.
