Token-indexed memory changes attention in Transformers
A post published on September 25, 2026 describes an architecture that sums contextual keys and token-indexed, layer-specific memory vectors, and allows the memory to reside in CPU memory.

What happened and what to do
In a post published on September 25, 2026, Memory Attention replaces the Transformer's learned value projection with a sum of contextual keys and token-indexed memory vectors specific to each layer. The post says the memory can reside in CPU memory and presents the approach as a way to add capacity to a model.
A company that develops or operates models can evaluate the architecture in a controlled experiment: define tasks and metrics, compare the approach with its current implementation, and monitor quality, latency, and memory use. Adoption should depend on results in the company's own environment and workloads.
How the consultancy can help
Wendelmaques can assess the opportunity, define a scope for evaluating the architecture, and implement the necessary tests and instrumentation. If results support adoption, it can also assist with implementation and operation on the company's infrastructure.
