Agent Model Access
Connect AI agents to 100+ text, image, video, speech, and embedding models through one OpenAI-compatible API. Add or change models without rebuilding provider-specific integrations.
Build dependable agentic applications with a unified gateway designed for high-volume, multi-step AI workflows. FastRouter connects agents to 100+ models through one OpenAI-compatible API while intelligently routing requests, applying guardrails, controlling spend, and preserving continuity during provider outages. Give your teams the operational control to move from prototype to production without maintaining separate model integrations.
Production controls, model access, and resilience for reliable, scalable agentic applications.
Connect AI agents to 100+ text, image, video, speech, and embedding models through one OpenAI-compatible API. Add or change models without rebuilding provider-specific integrations.
Route each agent request according to cost, latency, quality, or throughput priorities. FastRouter selects suitable available models per step, reducing hard-coded model decisions.
Keep multi-step agent runs moving through provider outages, rate limits, and model errors with prioritized fallback lists, automatic retries, and multi-provider redundancy.
Discover, consume, and govern Model Context Protocol servers through an enterprise-grade registry with routing, access controls, and observability for production agent teams.
Validate agent inputs and outputs centrally to catch unsafe, non-compliant, malformed, or policy-violating content before it reaches users or downstream systems.
Capture request-level logs, latency, cost, errors, and outcomes across agent runs. Use unified dashboards to debug multi-turn behavior and maintain performance standards.
FastRouter gives agent teams one durable control plane for the model calls that power autonomous workflows. Connect through an OpenAI-compatible API, then centrally manage routing, fallback, governance, guardrails, logging, and cost limits across providers. Agents can use efficient models for routine tool calls and stronger models for complex reasoning, while your team retains visibility into every request, outcome, and dollar spent.

"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."

A unified operational layer for teams running AI agents in production.
Reach 100+ models through one OpenAI-compatible integration instead of maintaining separate provider APIs.
Automatic fallback and multi-provider redundancy keep agent loops running through outages and rate limits.
Apply spend limits, roles, access policies, and guardrails consistently across every agent application.
Inspect model cost, latency, errors, and responses with unified logs, analytics, evaluations, and alerts.
A platform foundation for dependable production AI.
FastRouter is positioned as an LLMOps platform for teams that need to run AI reliably beyond the prototype stage. Its unified, OpenAI-compatible control plane brings multi-provider model routing, observability, experiment tracking, guardrails, cost governance, and evaluations into one operational layer. For agent builders, this means less time maintaining one-off provider integrations and more control over the high-volume, multi-step workflows that reach customers and internal teams. FastRouter supports access to 100+ models across modalities, helping organizations select and change models without unnecessary application rewrites. The platform’s vision is to empower businesses with intelligent AI solutions while giving engineering, product, finance, and security teams clearer oversight of production AI usage.
A gateway agent is an AI agent that accesses language models, tools, or external services through a gateway layer rather than connecting directly to a single provider. The gateway centralizes authentication, routing, fallback, governance, and monitoring. This architecture lets teams change underlying models, apply consistent policies, and maintain visibility across every step of an agent’s workflow without rewriting the agent’s provider integration.
