Product Overview
What is FastRouter?
FastRouter helps developers and enterprise teams manage multiple model providers through one OpenAI-compatible API. It combines model routing, failover, evaluation, and monitoring to balance cost, response quality, and latency. Teams can compare models before deployment, control spending across projects, and track production workloads without maintaining separate provider integrations.
Key Features
Unified Model Access
Access 200+ models for text, images, video, embeddings, and speech through one OpenAI-compatible API.
Intelligent Request Routing
Route requests based on cost, latency, quality, or throughput to match different workload requirements.
Automatic Failover
Use provider retries, prioritized fallback models, and virtual model lists to keep applications running through service failures.
Model Comparison and Evaluation
Compare model outputs, latency, and costs in a playground, or combine models to cross-check responses.
Spending Controls and Governance
Set project and API key limits, manage member permissions, and apply guardrails to model inputs and outputs.
Monitoring and Cost Insights
Track usage, errors, latency, and spending with dashboards, request logs, alerts, and ranked cost-saving recommendations.
Use Cases
- Multi-Model Application Development : Build applications that use models from different providers without maintaining a separate integration for each service.
- Production Reliability : Configure alternative providers and fallback models to reduce interruptions caused by outages or capacity limits.
- Model Selection : Test prompts across models to identify the best cost-quality balance for a specific product or workflow.
- Inference Cost Optimization : Route suitable tasks to lower-cost models and use spending insights to identify inefficient model usage.
- Enterprise Workload Management : Manage model access, budgets, and performance across teams and projects through a shared gateway.
