Three-Promise Contract

FusionLayer makes three performance promises: cheaper, better, and barely slower than a direct vendor call. This page shows where each promise stands today.

Summary
Measuring

Promise 1 — Cheaper

Cost reduction versus naive full-session token spend.
Data collection started. Results pending sufficient traffic.
Measuring

Promise 2 — Better

Quality lift versus single-vendor baseline.
Requires quality rating data from production sessions.
Measuring

Promise 3 — Barely Slower

Latency benchmark data not yet available.
Methodology
Pipeline latency is measured via an in-process canonical workload benchmark (mocked vendor calls, 500–2000 samples). It reflects routing, context injection, policy checks, and telemetry overhead — not vendor API latency, which varies by model and network.

Cost reduction and quality lift require production traffic with sufficient session depth. These metrics will populate as real usage data accumulates.

Benchmarks run nightly via GitHub Actions. Source: bench-out/three-promise.json.
