narration

The concentration test helped: a 50k-character cap improved dev perplexity again, from 333.8 to 330.1, while increasing document diversity from 9,635 to 11,175 pages. I’ll do one tighter cap comparison (25k); this directly tests whether the gain is from diversity or whether removing long-form books starts to cost useful coherence.

narration

The tighter cap confirms the mechanism: 25k characters improves perplexity to 325.2 and raises diversity to 12,967 pages. Since this remains monotonic and still allows multi-thousand-token documents, I’m testing 15k as the likely knee; below that, excessive EOS boundaries and loss of long-form exposition may begin to dominate.
