The goal is to enable Transformer LLMs to effectively process infinitely long inputs with bounded memory footprint and computation. They propose a new attention technique called Infini-attention which incorporates a compressive memory module into a vanilla attention mechanism.  It builds in both masked local attention and long-term linear attention into a single Transformer block. This allows the Infini-Transformer model to efficiently handle both long and short-range contextual dependencies. This approach outperforms baseline models on long-context language modeling with a 114x compression ratio of memory! They also show that a 1B LLM can naturally scale to a 1M sequence length and a 8B model achieves a new SoTA result on a 500K length book summarization task. Given how important long-context LLMs are becoming having an effective memory system could unlock powerful reasoning, planning, continual adaption, and capabilities not seen before in LLMs.
