Knowledge graph

Memory is a graph of facts kept between runs. A run reads what the organization already knows before it works, and a turn that completes teaches it what the run found.

  1. ReadMemory is readBefore and during the turn
  2. TurnThe turn worksTools, models, people
  3. DoneThe turn completesOnly a completed turn teaches
  4. WriteMemory is writtenFrom what the run recorded
Failed, cancelled and replaced turns teach nothing. Work done inside a called workflow or an agent is learned from once, when the turn that holds it completes.

Three graphs

GraphBelongs toWhat it holds
World
The organization
What the organization knows about the world, taught or learned: people, places, organizations, events and ideas.
User
The signed-in person
What Momor knows about the person, kept so answers fit them, including their preferences. It follows them across every organization they belong to.
Flow
One run
What the run has found, for its own later turns. Deleting the run erases it.

Each fact keeps where it came from. Memory points back to the run evidence behind a fact rather than copying it, and a fact supported by more independent sources carries more weight.

How a turn reads memory

  • The map. Every root turn’s instructions include a map of the organization’s world graph: what kinds of things it holds and how many.
  • Graph reads. Model steps of the root workflow whose output admits calls are offered GraphResolve, GraphExpand and GraphSource. A workflow’s Budget.MemoryProbes caps how many reads a turn makes.
  • Nested work reads none. A called workflow, an agent or a debater touches no graph: it is offered no graph reads and writes none.

Settings

Four settings belong to the organization. Workflows do not declare them and people cannot override them. The organization’s owner reads and changes them with GET and PATCH /organization/preferences, under workflow.

SettingDefaultWhat it decides
AllowEphemeralRuns
Off
Whether a run may be ephemeral at all. Off, a run asked for as ephemeral is stored as permanent.
LearnFromEphemeralRuns
On
Whether an ephemeral run teaches the world graph. Permanent runs always do.
LearnFromUsers
On
Whether a person’s own words, the request that opened a turn and their answers to questions, may become world knowledge.
NoMemoryShortcuts
Off
Whether every turn runs all its steps, even where memory already holds a strong enough answer.
Momor SearchSearch admits ephemeral runs, and learns neither from them nor from what people type, so public questions do not become memory.

Erasure

Deleting a run erases its flow graph. A person’s user graph is deleted with their account. Facts in the world graph stay as long as their own evidence and corrections allow; a deleted run’s contribution to a fact’s weight remains, without the run it came from.
