Lumen

Platform

Six layers, one continuous system

From the runtime up to the surfaces you touch, everything is observable, replayable and yours to inspect.

Architecture

Built in layers you can see through.

L1

Runtime

A streaming edge runtime with deterministic replay of every run.

L2

Retrieval

Hybrid lexical and vector recall over your own corpora, with citations.

L3

Reasoning

Planner and critic loops that trade latency for depth on demand.

L4

Evaluation

Continuous scoring against your rubrics, not a public leaderboard.

L5

Governance

Per-team policy, redaction and full audit of prompts and outputs.

L6

Surfaces

Workspace, API and SDKs that share one model of state.

Runs

Every answer has a paper trail.

01

Plan

Decompose the question into checkable sub-questions.

02

Gather

Retrieve, deduplicate and rank the evidence.

03

Reason

Draft, critique, revise — visible at each step.

04

Report

Deliver the answer with confidence and citations attached.
