LOCOMO, LLM-judged: 92.9%, above mem0's published 91.6.

Scored end-to-end by the unmodified mem0ai/memory-benchmarks harness (gpt-5 answerer + judge) over Lians retrieval · arctic-embed-l-v2.0 + tuned hybrid ranking · full report ↗

2026-07-06 · v0.4.0

The memory-lifecycle release: flush, resurface, decay, degrade, export.

Pre-compaction memory flushNew

Durable facts persist into governed memory before the host framework compacts context, automatic via CompactionGuard, with flush nodes/tools for LangGraph, the OpenAI Agents SDK, CrewAI, and AutoGen.

Signed Markdown memory statementNew

An agent's point-in-time knowledge state as a human-readable document, its SHA-256 anchored in the audit chain, so the statement you hand an examiner is itself tamper-evident.

Open conflicts resurface until adjudicatedNew

Unresolved conflicts ride at the top of every assembled context block as explicit "X disagrees with Y" lines.

Audited degraded retrievalNew

Embedding outages no longer take recall down: queries proceed lexical-only, with the degradation declared on every result and audit event.

Materiality-weighted retrieval decayNew

Retrieval half-life scales with materiality: passing preferences fade in 7 days, critical flags hold for 365.

Live on PyPI, npm, the Go module proxy, and Maven Central; deployed to managed cloud 2026-07-06. GitHub Release ↗
