A layered memory system for AI Agents that combines symbolic short-term memory with hierarchical long-term storage. It optimizes performance by offloading verbose tool logs into compact Mermaid symbols, reducing token usage by up to 61% while improving accuracy. The system organizes experiences into a semantic pyramid (L0-L3), enabling structured persona management instead of flat vector retrieval. Integrated with OpenClaw and Hermes, it provides a traceable and lossless memory architecture.
MemPalace is a local-first AI memory tool designed to store conversation history verbatim and retrieve it through semantic search, without summarizing or paraphrasing. It utilizes a structured index, categorizing information into "wings," "rooms," and "drawers" to enable scoped searches. The retrieval layer is pluggable (ChromaDB by default), ensuring all data remains on the user's machine unless opted out. It achieves an impressive 96.6% R@5 raw recall on the LongMemEval benchmark, notably without requiring LLMs or API calls, showcasing high performance in a local environment.
Agent S, developed by Simular AI, is an open-source framework enabling autonomous computer interaction via an Agent-Computer Interface (ACI). By pairing major LLMs with visual grounding models like UI-TARS, it translates natural language into precise mouse and keyboard actions. The latest Agent S3 features a local coding environment for Python/Bash execution and Behavior Best-of-N mechanisms. It demonstrates strong zero-shot generalization across platforms and is the first GUI agent to surpass human-level performance (72.60%) on the OSWorld benchmark.
OpenSquilla is a token-efficient, microkernel AI agent built for CLI, Web UI, and various chat channels. Its core feature is an on-device model router (SquillaRouter) that dynamically dispatches each turn to the most cost-effective capable model. With persistent memory, a layered sandbox, built-in web search, and a pluggable provider layer supporting multiple LLMs, it maximizes intelligence density on the same budget.
