// AGENTIC RUNTIME v4.1

AETHER is the runtime for autonomous systems that can be trusted. Compose reasoning, tools, memory and guardrails into production agents — then replay every decision, deterministically, forever.

01 — Platform

Everything an agent needs.
Nothing it doesn't.

Six primitives, one runtime. Each layer is observable, versioned and independently scalable — so a prototype becomes a product without a rewrite.

Reasoning Engine

A planner that decomposes ambiguous goals, weighs competing strategies and revises its own plan mid-flight — with a full trace of every thought.

chain-of-thought · self-critique

Tool Synthesis

Point it at an API, a database or a schema. AETHER writes, type-checks and sandboxes the tool it needs before it ever calls it.

OpenAPI · SQL · MCP

Memory Fabric

Vector, episodic and semantic memory unified behind one query surface, with decay, provenance and tenant isolation built in.

vector · episodic · TTL

Multi-Agent Swarms

Fan out to hundreds of specialised workers, negotiate shared state, then converge on a single answer without a central bottleneck.

Guardrails

Policy-as-code around every tool call: least privilege, budget caps, PII redaction and human-in-the-loop escalation points.

Deterministic Replay

Every run is a sealed artifact. Replay it byte-for-byte in staging, diff two versions, and prove a fix before it ships.

02 — Architecture

How a single prompt
becomes a coordinated system.

The planner decomposes, workers execute in parallel, and the synthesizer resolves their findings into one defensible answer. Every hop is traced and replayable.

03 — Showcase

Watch a swarm
think out loud.

A real transcript shape, streamed from the runtime. Fourteen sources in, one cited synthesis out — in under nine seconds.

We replaced a twelve-service orchestration stack with one AETHER graph. Nothing broke, everything got faster, and for the first time we can explain exactly why an agent did what it did.

Build with Aether

Ship your first autonomous workflow this week. Bring a use case — we’ll bring the runtime, the guardrails and the replay.
