A New Agentic Memory Framework Uses 118K Tokens Per Query -- LangMem Burns 3.26M
A newly detailed agentic memory framework reportedly answers queries using about 118,000 tokens, versus roughly 3.26 million for the widely used LangMem approach -- a ~28x efficiency gain. As AI agents take on longer, multi-step tasks, how they store and retrieve memory is becoming a decisive factor in both cost and capability.

7,000 Langflow Servers Are Under Attack -- and LangGraph and LangChain Share the Holes
Roughly 7,000 internet-exposed Langflow servers are being actively exploited, and researchers warn the same class of flaws extends to LangGraph and LangChain -- the orchestration backbone of much of today's agent stack. It's a stark reminder that the rush to ship AI agents has outpaced the security hardening underneath them.

7,000 Langflow Servers Are Under Active Attack -- and LangGraph and LangChain Share the Holes
Roughly 7,000 internet-exposed Langflow servers are under active attack, and security researchers warn that the same class of vulnerabilities extends to LangGraph and LangChain -- the de facto plumbing of the agent boom. As enterprises rush AI agents into production, the orchestration layer is emerging as a soft, high-value target.
