Alibaba Cloud Bailian adds "memory bank" to give AI Agents long-term memory

What was released

Alibaba Cloud Bailian (阿里云百炼) has formally launched a "memory bank" feature that gives AI Agents cross-session, long-term memory. The feature is reportedly free for a limited time and can be called directly via API or installed with one click through Agent marketplaces such as OpenClaw. The move aims to shift Agents from single-session chatbots toward persistent, personalized assistants.

How it works

The memory system is built around four modules — extract, store, retrieve and inject — so the agent can automatically capture key information at the end of each conversation and reinsert relevant memories into later contexts. Developers get white‑box configuration for memory rules, allowing extraction of user profiles (for example, "personality" or "shopping habits") and scene‑specific snippets such as "family relationships." Built‑in templates are said to cover use cases from consumer electronics and customer service to emotional companionship, and reportedly cut configuration costs by about 50%.

Performance and risks

Alibaba Cloud says the memory bank uses a special retrieval algorithm to speed and improve recall: it has been reported that average retrieval latency (RT) falls roughly 50%, date‑related answers improve by 66%, and content relevance by 39%. Those performance gains could accelerate the adoption of agent-based services, but they also raise data‑protection and governance questions. Persisting cross‑session memories heightens the need for clear consent, retention policies and compliance with China’s tightening data and algorithm regulations.

Bigger picture

This launch is part of a broader effort by Chinese cloud and AI firms to productize agent capabilities even as global tensions shape the supply chain for high-end AI chips and models. Will long‑memory agents change user expectations for convenience — and for privacy? For now, Alibaba Cloud Bailian has given developers a fast path to build more personalized agents, while regulators and customers will watch how those persistent memories are stored, accessed and controlled.
