Failed Implementation: 'Leave No Context Behind, Infinite Context Transformers'

Overview

This write-up documents an exploratory effort to implement the Infini-attention mechanism from the paper “Leave No Context Behind: Efficient Infinite Context Transformers with Infini-attention.” While the attempt did not yield a working prototype, the process highlighted key design difficulties and implementation bottlenecks in adapting attention architectures to unbounded contexts.

A follow-up article will dive into lessons learned, including challenges with chunkwise recurrent processing, memory state tracking, and stability in decoder-only models.
