DeepSeek R1 thinking-mode release convergent with sequential-recursion anchor

The claim - verbatim

Michael Darius Eastwood first reported that recursive sequential processing amplifies AI reasoning ('each iteration learns from and builds upon the last') in the 8 December 2024 manuscript at V1 line 148. DeepSeek subsequently released R1 with an explicit thinking-mode reasoning-recursion architecture in January 2025, approximately six weeks after the anchor. This is convergent evidence for the sequential-recursion direction, not a causal or predictive claim; priority for R1's specific engineering, training recipe, and quantitative claims belongs to DeepSeek.

Limits and citation guidance - what this claim does not support, and how to cite it

Limits. Convergent, not causal. The anchor supports only the directional claim about sequential-recursive processing.
