Token retention may reduce reliance on the KV cache
A publication dated September 13, 2026, claims that keeping four initial tokens and a 64-token window without training matches or exceeds distilled linear-attention models on nearly all benchmarks.

What happened and what to do
The September 13, 2026 publication claims that a no-training strategy, retaining four initial tokens and a 64-token window, matches or exceeds distilled linear-attention models on nearly all benchmarks. The approach may reduce reliance on the KV cache, but its impact needs to be measured against a company’s models and workloads.
A practical implementation starts with controlled tests: compare quality, latency, and memory use between the current configuration and token retention, using representative tasks and defined acceptance criteria. A company can then integrate the alternative into its inference service, monitor results, and retain a rollback path in case of regressions.
How the consultancy can help
Wendelmaques can diagnose inference and memory requirements, scope an evaluation, implement tests and integration on the company’s infrastructure, and establish solution operations and monitoring.
