Unified Multi-LLM Gateway

One API for
Every LLM Provider

Route between Claude, GPT-4, Gemini, and 20+ LLMs with intelligent failover

Stop managing multiple API keys, billing accounts, and rate limits. G8KEPR gives you one unified API that automatically routes to the best provider based on cost, latency, or task type.

What is an AI Gateway?

The missing infrastructure layer for production LLM applications

The Multi-LLM Challenge

Production AI apps need multiple LLM providers for reliability, cost optimization, and feature coverage. But managing multiple providers means juggling separate API keys, billing accounts, rate limits, and error handling.

API Key Management
Separate keys for OpenAI, Anthropic, Google, Azure, Bedrock...
Cost Tracking
Different pricing per model - Claude $3/M, GPT-4 $30/M, Gemini $0.50/M
Rate Limit Handling
Each provider has different limits - OpenAI 10k RPM, Anthropic 50 RPM
Failover Logic
Manual retry logic when OpenAI is down - switch to Claude or Gemini

The Traditional Approach

Most teams hard-code provider-specific logic throughout their codebase. Every provider switch requires code changes, redeployment, and testing. Cost tracking is manual. No failover.

Vendor Lock-In
Switching from OpenAI to Claude requires changing every API call
No Failover
If OpenAI goes down, your entire app is down
Hidden Costs
No visibility into which models/users cost the most
Scattered Logic
Provider-specific code duplicated across services

How G8KEPR AI Gateway Works

One unified API that intelligently routes to the best LLM provider

Intelligent LLM Routing
1. Your Application
client.chat.completions.create(model="auto")

Single API call with model="auto" - no provider-specific code

2. G8KEPR Routing Engine
Selects optimal provider
Check Costs: Claude $3/M, GPT-4 $30/M, Gemini $0.50/M
Measure Latency: Claude 145ms, GPT-4 180ms
Health Check: Is provider available?
Rate Limits: Has quota remaining?

✓ Routed to Claude • Cost-optimized • 145ms response • Failover to GPT-4 if unavailable

Cost-Based Routing

Always route to cheapest provider. Gemini ($0.50/M) for simple tasks, Claude ($3/M) for complex reasoning.

✓ Save 90% on costs

Latency-Based

Route to fastest provider based on real-time metrics. Critical for user-facing chat applications.

✓ Sub-200ms responses

Task-Based

Match task to best model. Code → Claude, Chat → GPT-4, Analysis → Gemini based on your rules.

✓ Best quality per task

Round Robin

Distribute load evenly to prevent rate limits. Essential when hitting 10k RPM limits on OpenAI.

✓ No rate limit errors

AI Gateway Features

Everything you need to manage multi-LLM applications in production

BYOK (No Markup)

Use your own API keys for OpenAI, Anthropic, Google. We never mark up LLM costs - you pay providers directly at published rates.

✓ Your $3/M stays $3/M

Automatic Failover

If primary provider is down or rate limited, automatically fail over to backup provider. Configure fallback chains: Claude → GPT-4 → Gemini.

✓ 99.99% uptime SLA

Per-User Cost Tracking

Tag requests with user_id, team_id, or project_id. Track costs per user, set budgets, generate chargebacks. Export to CSV or API.

✓ Track costs by any dimension

Real-Time Latency Metrics

Track P50, P95, P99 latency per provider and model. Route to fastest provider automatically. Set latency SLOs and get alerts.

✓ Sub-200ms responses

Rate Limit Management

Respect provider rate limits (OpenAI 10k RPM, Claude 50 RPM). Queue requests, distribute load with round-robin, prevent 429 errors.

✓ Zero rate limit errors

Health Monitoring

Continuous health checks for all providers. Automatic circuit breakers when providers degrade. WebSocket alerts for downtime.

✓ Always know provider status

Request Logging

Complete audit trail of all LLM requests. Log prompts, responses, costs, metadata. Debug failed requests, replay for testing.

✓ Full observability

Multi-Region Routing

Route to providers closest to users. US-East for US users, EU for European users. Reduce latency with intelligent geo-routing.

✓ Global edge network

OpenAI SDK Compatible

Drop-in replacement for OpenAI SDK. Change base URL and start using all providers. No code changes to your application logic.

✓ One line integration

AI Gateway FAQs

Everything you need to know about multi-LLM routing

Calling LLM APIs directly means managing separate API keys, billing accounts, rate limits, and error handling for each provider (OpenAI, Anthropic, Google, etc.). An AI Gateway gives you one unified API that routes to all providers. Change providers in one line of config, not scattered across your codebase. Get unified cost tracking, automatic failover, and intelligent routing - impossible when calling APIs directly.
