Our Gemini 3 API Services

Access, operate, evaluate, and govern Gemini workloads through one production-ready AI platform.

Gemini 3.1 Access

Use Gemini 3.1 Pro through FastRouter’s unified, OpenAI-compatible API. Add Gemini to existing applications without maintaining a separate provider-specific integration or workflow.

Intelligent Routing

Route requests across Gemini and other models according to cost, latency, throughput, or output-quality priorities. Update model selection centrally instead of hard-coding decisions into every application.

Automatic Failover

Configure fallback models and providers to protect Gemini-powered experiences from outages, rate limits, and model failures. Failed requests can be rerouted automatically with no manual intervention.

Multimodal API

Build workflows that combine Gemini’s multimodal input capabilities with text, image, video, speech, and embedding models through the same unified endpoint and controls.

Observability Insights

Monitor Gemini API traffic with unified logs, real-time metrics, latency data, error rates, usage details, and searchable request records for faster troubleshooting and optimization.

Governance Controls

Apply project and API-key spending limits, member roles, and access controls at the gateway. Keep Gemini usage accountable across teams without adding policy logic to each application.

Unified AI Operations

Run Gemini Workloads With More Control

FastRouter gives teams a durable way to use Gemini 3.1 Pro in production without creating another isolated provider integration. Send requests through one OpenAI-compatible endpoint, then compare Gemini with GPT and Claude, set routing priorities, and establish fallback protection. Unified logs, evaluations, cost controls, and access policies help engineering, product, and platform teams make informed model decisions while maintaining reliable, accountable 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."

"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."

The FastRouter Platform Team

Built for teams operating AI reliably in production.

FastRouter is an LLMOps platform designed to simplify the operational work of running production AI. Its single OpenAI-compatible control plane brings multi-provider model routing, real-time observability, experiment tracking, guardrails, cost governance, and evaluations together across more than 100 models. For teams adopting Gemini 3.1 Pro, the platform provides a consistent path to integrate, compare, monitor, and govern model traffic without building separate tooling for each provider. FastRouter focuses on the practical requirements that emerge after an AI feature moves beyond a prototype: dependable routing, detailed request visibility, disciplined spending, safer outputs, and repeatable quality checks. The result is a more manageable AI foundation for engineering, product, platform, and enterprise teams.
