Building CIEL

Memory for
long-running
AI agents.

We’re building CIEL to help agents carry important context across conversations, code, and decisions.

The idea behind CIEL

Keep the thread.

Useful context lives across conversations, code, tool output, and documents. CIEL explores how to keep the relevant pieces available as the work moves forward.

It is a research prototype. We’re studying three complementary roles for memory, and evaluating them on long histories.

Continuity, across the work.

Working memory

The decisions and constraints that should stay close to the task.

Recent context

The latest conversation, code, and tool output that inform the next step.

Older details

Relevant information from earlier work, brought back when it is needed.

We’re looking for teams building agents that work over time.

Bring a real
workflow.

We are looking for a team with a long-running coding, research, support, or operations agent to test CIEL on a real workflow.
