Infini Memory: Maintainable Topic Documents for Long-Term LLM Agent Memory

arXiv:2606.10677v1 Announce Type: cross Abstract: Long-term LLM agents need persistent memory that can track changing facts and provide relevant evidence across sessions. Existing memory systems often store observations as isolated records, summaries, or indexed fragments, which makes evidence aggregation, fact revision, and memory maintenance difficult. We propose Infini Memory, a maintainable text-based persistent memory architecture that treats agent memory as topic-structured documents. Each topic document serves as a semantic unit for collecting related evidence, preserving metadata, and

Why this matters
Why now

The rapid advancement of LLM capabilities is pushing the boundary of agentic systems, necessitating more sophisticated memory architectures for practical application.

Why it’s important

Improved long-term memory for LLM agents is critical for their sustained utility and autonomy, enabling them to handle complex, multi-session tasks efficiently.

What changes

This proposal offers a method for LLMs to manage and update their persistent memory more effectively, moving away from isolated records to structured, maintainable topic documents.
