# Zep Q1 Product Round-up

By Jack Ryan · Mar 25, 2025 · https://www.getzep.com/blog/zep-q1-2025-product-round-up/ · Tags: Product updates, Benchmarks and evaluation, Context graphs

Graph Explorer, an upgraded Playground, and a practical Cookbook—giving developers more control, better graph quality, and improved usability.

In Q1, we shipped updates to Zep focused on improving developer control over knowledge graphs, a significant improvement to fact and graph quality, and overall platform usability. The highlights include a [Graph Explorer](#graph-explorer) for visualizing user and group knowledge graphs directly in the web app, a redesigned [Playground](#new-playground) emphasizing our graph-based memory architecture, and a practical [Cookbook](#cookbooks) featuring concrete examples for customizing Zep's functionality.

Below, we'll break down these updates and new features in more depth.

## Zep is the State of the Art in Agent Memory

In research we [published in January](https://www.getzep.com/blog/state-of-the-art-agent-memory/), Zep outperformed MemGPT on the Deep Memory Retrieval (DMR) benchmark, achieving a 94.8% accuracy compared to MemGPT’s 93.4%; however, the study noted DMR’s limitations in assessing practical performance due to advancements in LLMs.

More importantly, Zep demonstrated stronger results on the LongMemEval benchmark, which aligns more closely with real-world enterprise scenarios, delivering aggregate accuracy improvements of up to 18.5%, with some individual cases surpassing 100%, and simultaneously reducing response latency by 90%.

### Graph Explorer

You can now visualize and explore every knowledge graph you create, by visiting the page of the relevant user or group in [the web app](https://app.getzep.com/).

### New Playground

We released a new version of [the Playground](https://app.getzep.com/playground) that focuses on our new graph-based memory design. The new playground allows you to:

- Explore the knowledge graphs from preloaded datasets
- Add arbitrary message, JSON, or text data to these data sets and see how the graph changes
- See how the graph, the memory context string, and an LLM's answer to a question change in response to new data

### Cookbooks

In our new [Cookbook](https://help.getzep.com/cookbook/customize-your-memory-context-string), you can find guided examples of techniques you can use to fully utilize Zep, such as [customizing your memory context string](https://help.getzep.com/cookbook/customize-your-memory-context-string) or [sharing memory across users using group graphs](https://help.getzep.com/cookbook/how-to-share-memory-across-users-using-group-graphs).

### Other Updates

Other additions include:

- **Enhanced data ingestion:** Upgraded models provide higher-quality data ingestion into Zep knowledge graphs.
- [**ignore_role option**](https://help.getzep.com/memory#ignore-assistant-messages): Exclude assistant (or other role) messages from graph ingestion for cleaner, more focused graphs.
- [**Delete episode method**](https://help.getzep.com/deleting-data-from-the-graph#delete-an-episode)**:** Easily remove specific Episodes from your graph.
- [**Add fact triple method**](https://help.getzep.com/adding-data-to-the-graph#adding-custom-factnode-triplets): Directly insert structured data into graphs using node-edge-node relationships.
- [**Get user node method**](https://help.getzep.com/users#get-the-user-node)**:** A convenience method for easily returning the User node in a User graph
- [**Returning the created Episode UUID**](https://help.getzep.com/adding-data-to-the-graph#managing-your-data-on-the-graph): The graph.add method now returns the newly created episode UUID for immediate use.
