LLM Gateway
Connect once to access 100+ models through a single OpenAI-compatible API, spanning text, image, video, speech, embeddings, and major AI providers without separate integrations.
FastRouter gives engineering, product, and platform teams one control plane for production LLM operations. Route requests across 100+ models, monitor latency and spend, run evaluations, enforce guardrails, and prevent provider outages from disrupting users. Use an OpenAI-compatible API to standardize model access while keeping reliability, governance, and cost optimization built into every application at scale.
FastRouter unifies routing, reliability, monitoring, governance, evaluations, and cost control for production LLM applications.
Connect once to access 100+ models through a single OpenAI-compatible API, spanning text, image, video, speech, embeddings, and major AI providers without separate integrations.
Automatically send each request to the best model for cost, latency, quality, or throughput. Central routing policies eliminate hard-coded choices and simplify optimization.
Monitor latency, uptime, cost, token usage, errors, and request logs in unified dashboards, giving teams complete visibility across every provider and model.
Run structured evaluations to compare model outputs, validate quality, detect drift, and make defensible model decisions before and after production deployment.
Validate inputs and outputs at the gateway to enforce safety, compliance, formatting, and consistency rules across all models before responses reach users.
Set project limits, API-key spend controls, roles, access policies, alerts, and analytics to keep AI usage accountable, predictable, and governed.
FastRouter turns scattered model integrations into a governed production LLMOps layer. Teams connect once, route across leading providers, compare models, monitor every request, and apply safety controls without rewriting application code. With unified billing, alerts, fallback policies, and evaluations in one platform, engineering leaders can ship AI features faster while reducing downtime, cost surprises, and operational risk.
See how production teams can standardize model operations, improve resilience, and control AI spend.
"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 gives teams the operational backbone needed to run LLM-powered products with confidence.
Manage routing, observability, governance, and evaluations from one OpenAI-compatible production control plane.
Access major providers and modalities through one integration without provider-specific maintenance work.
Automatic failover and fallback lists keep production applications running through outages and rate limits.
Project limits, API-key controls, analytics, and billing visibility prevent unexpected LLM spend spikes.
Meet the platform built for production AI operations.
FastRouter is built around a clear vision: production AI teams need more than access to models; they need an operational foundation for reliability, governance, and continuous improvement. The platform brings model routing, observability, evaluations, guardrails, experiment tracking, and cost controls into one OpenAI-compatible control plane. By abstracting provider-specific integrations, FastRouter helps engineering and platform teams move faster while reducing operational complexity. Its focus is practical LLMOps: keeping AI applications available during provider issues, making cost and quality measurable, and giving organizations a consistent way to manage model usage across teams, products, and workloads.
An LLMOps platform helps teams deploy, monitor, govern, evaluate, and optimize large language model usage in production. FastRouter provides these capabilities through one OpenAI-compatible control plane, including model routing, observability, guardrails, cost governance, experiment tracking, and evaluations. Instead of managing separate provider integrations, teams can standardize production AI operations across 100+ models.
