Paper reports gains from redistributing capacity across layers
Research on language models reports that cosine-shaped capacity allocation improved perplexity without increasing parameters or FLOPs.

What happened and what to do
Published on July 5, 2026, the paper investigates uniform parameter allocation across language-model layers. It reports that a cosine-shaped taper, with more capacity in earlier layers, improved perplexity across several architectures and scales without increasing parameter counts or FLOPs.
A company training or adapting models could test this approach in a controlled pipeline: compare cosine-shaped and uniform allocation, keep parameter and compute budgets constant, and monitor perplexity alongside metrics relevant to the application. The experiment can inform architecture decisions before increasing investment in training.
How the consultancy can help
Wendelmaques can assess the opportunity, define a comparison protocol, and implement an experimentation and monitoring pipeline. The scope can include operating the tests and analyzing results to support model architecture decisions.
