Cost Governance
Set project and API-key spend limits, assign member roles, and enforce access controls at the gateway to prevent bill spikes and keep LLM usage accountable.
Take control of LLM spend before it becomes unpredictable. FastRouter helps teams manage budgets across providers with unified billing, spend limits, usage analytics, alerts, and cost-optimized routing—so engineering can keep shipping while finance gains clear visibility into every token, model, project, and team driving AI costs.
FastRouter unifies LLM cost visibility, billing, routing, alerts, and governance across providers.
Set project and API-key spend limits, assign member roles, and enforce access controls at the gateway to prevent bill spikes and keep LLM usage accountable.
Use intelligent routing, automated model selection, batching, and live-traffic audits to reduce AI API spend without sacrificing reliability or output quality.
Track token usage, request volume, model consumption, provider costs, project spend, and team attribution from one unified dashboard.
Consolidate OpenAI, Anthropic, Google Gemini, xAI Grok, and other provider bills into one reconciled view with clearer reporting.
Audit live API traffic to compare cost, quality, latency, and reliability, then receive a practical report highlighting savings opportunities.
Receive real-time notifications when usage, cost, latency, or error rates exceed defined thresholds, helping teams catch budget anomalies early.
FastRouter gives engineering, platform, and finance teams a shared source of truth for LLM costs. Instead of juggling separate provider dashboards and unpredictable token bills, you can monitor usage, apply budget limits, optimize routing, and reconcile spend in one OpenAI-compatible control plane built for production AI operations.

"Excellent platform to test the latest LLMs for our use case. With new LLMs coming out every few weeks and benchmarks not giving the full picture, I rely on Fastrouter.ai to optimize my cost vs quality balance."
"Amazing product. Have had a great experience using FastRouter. Reliable access to models across providers helps removes the worry about outages or vendor lock-in."
"FastRouter is a good value add, specifically when you are not sure which LLM is better for your use cases. You can play around with models, can compare against them, and then use normal OpenAI compatible APIs call to leverage the full potential of it."

FastRouter helps teams make LLM spend measurable, governable, and easier to optimize.
Manage spend, routing, observability, and governance across providers from one unified control plane.
Apply project and key-level limits automatically without rebuilding budget controls per application.
Route requests to cost-efficient models while maintaining your chosen quality, latency, and reliability goals.
Consolidate invoices, analytics, logs, and alerts so finance and engineering share clear cost data.
A control plane built for production AI operations.
FastRouter is built for teams that need more than a basic LLM gateway. Its platform unifies routing, observability, experiment tracking, guardrails, cost governance, and evaluations into one OpenAI-compatible control plane across 100+ models. The vision is to give engineering and platform teams the operational foundation required to run AI reliably in production while giving finance and leadership clearer budget accountability. By centralizing model access, spend limits, usage reporting, fallback policies, and provider billing, FastRouter helps organizations move faster without losing control of cost, performance, or governance as AI adoption expands.
LLM budget management is the practice of tracking, controlling, and optimizing AI model spend across teams, projects, keys, models, and providers. FastRouter supports this by routing all requests through one control plane, where usage analytics, spend limits, consolidated billing, alerts, and cost-optimized routing help prevent surprise bills while keeping applications running reliably.
