Glossary

Routing

Tier — one of light, standard, heavy. Each tier maps to a set of provider models with similar price/quality.

Routing profile — budget, balanced, or quality. Shifts the thresholds between tiers: budget routes aggressively to light, quality to heavy.

Scoring — the deterministic 7-analyzer pipeline that produces a 0.0–1.0 complexity score for each request, used to pick a tier.

Pinning — bypassing the router by setting model to a specific tier or provider model. Useful for A/B testing or when you want deterministic model selection.

Billing

Mandat transparent — the legal structure under which HiWay settles provider costs on your behalf. Keeps the disbursements outside French VAT scope (CGI art. 267-II-2°).

Débours — the pass-through cost of a provider call. Out of VAT scope, zero markup.

Subscription fee — the flat monthly fee HiWay charges for routing intelligence. Within VAT scope (20% in France).

Fee-free allowance — the first $10 of cumulative credits per user, exempt from the 5% commission. One-time per account.

Compte de passage — accounting account 467 where unused credits are held, separate from HiWay's operating revenue.

Safety

Guardian — the anti-loop / anti-spike safety system. Three rules: duplicate detector, cost spike, zombie agent.

Strict spend protection — the pre-flight reservation system that prevents overdraft by reserving the worst-case cost before forwarding a request.

Drift detection — the 24h background poller that compares our pricing (providers.py) against the LiteLLM catalog to detect silent provider price changes.
