ENTERPRISE SCALE MEMORY

Introducing the Context Lake

Millions of context graphs, governed and served as one system. The data-lake pattern, applied to agent context. Powered by Zep’s proprietary Context Graph Engine.

Sub-200ms retrieval

Retrieval stays under 200 milliseconds, regardless of graph size or count.

Governed at the substrate

Authorization, retention, and audit live in the substrate, not bolted on. Policy applies across every graph, every query, every layer.

“I only wear Adidas shoes. I love them!”

Provenance preserving

Every fact in the graph traces back to the source episode that produced it. Audit any answer back to where it came from.

Recognition

Agent memory infrastructure for the enterprise.

We can easily see Zep becoming a de facto partner in this layer of the enterprise agent stack.

— Melissa Incera, S&P Global Market Intelligence

Memory that understands when things change

When new information contradicts what’s in the graph, Zep invalidates the old fact. Your agent reasons with the latest decisions, traits, and behaviors.

Old facts stay as history. Ask what’s true now, or what was true on any past date.

Memory patterns become Observations

Zep analyses the structure of the graph to surface Observations: patterns, recurrences, and co-occurrences in memory. Your agent gains a global perspective, beyond facts and summaries.

Three Lines of Code

Add memory to your agent in minutes. Works with any agent framework, or none.

quickstart.py
# Add messages and get context in one callresponse = client.thread.add_messages(    thread_id=thread_id,    messages=[Message(name="Jane", role="user", content="I'd like to upgrade my plan...")],    return_context=True,) # Add business data to the user's graphclient.graph.add(    user_id=user_id,    type="json",    data=json.dumps({"event": "plan_upgrade", "to": "pro", "mrr": 49}),) # Get relevant contextuser_context = client.thread.get_user_context(thread_id=thread_id)

Governed at the substrate

Govern context across thousands of agents, users, and context sources.

Access control

Attribute-based access control

Control what context agents can access and what they can do with it.

INGESTEXPIRE30d windowLEGAL HOLD
Retention

Retention policies

Retention is policy-driven. Data expires on the schedule you set. Legal hold blocks deletion when compliance requires it.

Audit and API logs

Detailed logs of every request and policy decision, ready for audit.

More accurate. Faster. Fewer tokens.

Agent memory systems often trade one for another. Zep leads on all three.
