Null Drift

Null Drift is an AI-agent memory system described as a holographic reversible state accumulator. It projects semantic embeddings into a 10,000-dimensional bipolar phase space, where salience and temporal permutation are used to retain event relationships and emphasize higher-salience information. Its documented components are a Rust daemon for isolated thread states, a Rust gateway that generates embeddings with fast

Practical overview

When it fits

Consider Null Drift when building an agent that needs thread-separated state accumulation, recall, or checkpointing, particularly when the project’s Rust services and listed CrewAI or LangGraph adapters suit your architecture.

Who it is for

  • Developers adding persistent episodic memory to AI agents.
  • Teams using CrewAI or LangGraph that want to explore the listed adapters.
  • Builders who want to manage agent state through thread-isolated HTTP operations.

Documented uses

  • Add text and a salience value to an agent thread’s memory.
  • Request a thread’s dominant state for use in an agent workflow.
  • Save an active memory index to a binary checkpoint and restore it to daemon memory.
  • Explore reducing model context tokens by accumulating state rather than repeatedly supplying a growing event history.
Before you choose

Requirements & limits

The repository is public and identifies an AGPL-3.0 license.

  • The architecture has distinct daemon and gateway services; the README’s Docker Compose command starts both.
  • The gateway path uses fastembed with ONNX Runtime, while the README also describes injecting embeddings directly into the daemon.
  • CrewAI and LangGraph adapters are listed; the excerpt does not provide their setup instructions.
  • The README reports token, latency and memory benchmarks, but these are project claims rather than independently confirmed results.
  • The project is licensed under AGPL-3.0, which may affect how developers can use or distribute modifications.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Start the services with Docker Compose

Build and start the documented Null Drift backend and gateway using Docker Compose.

Before you start

  • Docker Compose, as required by the README command.
  • The Null Drift repository, including its Compose configuration.

Steps

  1. From the repository, run the command below.

    Documented command
    docker compose up --build -d

  2. Use the gateway exposed at http://localhost:8000, as described in the README.

Expected outcome

The README says this starts the nulld backend and exposes the gateway on localhost:8000.

Guide limitations

  • This documented setup procedure does not cover agent integration or demonstrate that a particular deployment succeeds.

Inject and recall a thread’s memory

Use the documented gateway examples to add a memory item to a thread and request its dominant state.

Before you start

  • A running Null Drift gateway reachable at http://localhost:8000.
  • A thread ID to use in the request query parameter.

Steps

  1. Send a POST request to /inject?thread_id=agent_007 with JSON text and a salience value, following the README example.

  2. Send a GET request to /recall?thread_id=agent_007 to request the thread’s dominant state.

Expected outcome

The requests add an item to the named thread and ask the gateway to return its dominant state.
