# A3M Manifesto — Intelligent Multi-LLM Routing

*The intelligence layer between your app and every model.*

---

## The Problem

LLM ops are noisy. Expensive. Fragile.

You choose providers one at a time. Bills accumulate. Providers fail silently. Quality varies across models. And when one provider fails, everyone retries at once — making the problem worse.

**Sequential fallback is the default. It shouldn't be.**

## The Insight

Every query is different. Some need deep reasoning. Some need creative writing. Some need quick lookups. Most don't need GPT-4o — but you pay for it anyway.

**Nobody does parallel multi-LLM execution with result merging. Everyone does sequential fallback (try A → B → C).**

## The Solution

A3M Router is a routing layer that sits between your app and every LLM provider. It:

1. **Routes** every query to the cheapest capable model (99.5% accuracy)
2. **Executes in parallel** when quality matters (ensemble voting)
3. **Enforces budgets** with hard caps per user and team
4. **Recovers gracefully** when providers fail (circuit breaker, failover)
5. **Learns from history** (persistent memory, exponential moving average)

## The Principles

1. **Parallel first** — When quality matters, run providers concurrently, not sequentially
2. **Transparent scoring** — Every ensemble result shows why it won
3. **Cost-aware** — Route simple queries to cheap providers automatically
4. **Zero ML** — Heuristic routing achieves 99.5% accuracy without GPUs or training
5. **Self-hosted** — No vendor lock-in, no account required
