MoDA connects attention across LLM layers
Published on April 19, 2026, the paper presents MoDA, a mechanism combining key-value pairs from the current layer with information from earlier layers.

What happened and what to do
Published on April 19, 2026, the paper presents Mixture-of-Depths Attention (MoDA). The mechanism lets each attention head access sequence key-value pairs in the current layer and depth key-value pairs from earlier layers. The proposal addresses signal degradation in deeper large language models.
A company developing or adapting models can evaluate this approach in controlled experiments: compare architectures with and without access to information from earlier layers, and monitor quality, memory use, latency, and stability on relevant tasks. Decisions should be based on measured results in the company’s environment and with its data.
How the consultancy can help
Wendelmaques can diagnose the opportunity, define an evaluation scope, and implement the experiment and monitoring pipeline. It can also support operation of the selected solution on the client’s infrastructure.
