AI Gateway

Route to 250+ LLMs with 1 fast & friendly API

Docs | Enterprise | Hosted Gateway | Changelog | API Reference

The AI Gateway is designed for fast, reliable & secure routing to 1600+ language, vision, audio, and image models. It is a lightweight, open-source, and enterprise-ready solution that allows you to integrate with any language model in under 2 minutes.

• Blazing fast (<1ms latency) with a tiny footprint (122kb)
• Battle tested, with over 10B tokens processed everyday
• Enterprise-ready with enhanced security, scale, and custom deployments

What can you do with the AI Gateway?

• Integrate with any LLM in under 2 minutes - Quickstart
• Prevent downtimes through automatic retries and fallbacks
• Scale AI apps with load balancing and conditional routing
• Protect your AI deployments with guardrails
• Go beyond text with multi-modal capabilities
• Explore agentic workflow integrations
• Manage MCP servers with enterprise auth & observability using MCP Gateway

[!TIP] Starring this repo helps more developers discover the AI Gateway 🙏🏻

Quickstart (2 mins)

1. Setup your AI Gateway

# Run the gateway locally (needs Node.js and npm)
npx @portkey-ai/gateway

The Gateway is running on http://localhost:8787/v1

The Gateway Console is running on http://localhost:8787/public/

2. Make your first request

# pip install -qU portkey-ai

from portkey_ai import Portkey

# OpenAI compatible client
client = Portkey(
    provider="openai", # or 'anthropic', 'bedrock', 'groq', etc
    Authorization="sk-***" # the provider API key
)

# Make a request through your AI Gateway
client.chat.completions.create(
    messages=[{"role": "user", "content": "What's the weather like?"}],
    model="gpt-4o-mini"
)

Supported Libraries:   JS   Python   REST   OpenAI SDKs   Langchain   LlamaIndex   Autogen   CrewAI   More..

On the Gateway Console (http://localhost:8787/public/) you can see all of your local logs in one place.

3. Routing & Guardrails

Configs in the LLM gateway allow you to create routing rules, add reliability and setup guardrails.

config = {
  "retry": {"attempts": 5},

  "output_guardrails": [{
    "default.contains": {"operator": "none", "words": ["Apple"]},
    "deny": True
  }]
}

# Attach the config to the client
client = client.with_options(config=config)

client.chat.completions.create(
    model="gpt-4o-mini",
    messages=[{"role": "user", "content": "Reply randomly with Apple or Bat"}]
)

# This would always response with "Bat" as the guardrail denies all replies containing "Apple". The retry config would retry 5 times before giving up.

You can do a lot more stuff with configs in your AI gateway. Jump to examples →

MCP Gateway

MCP Gateway provides a centralized control plane for managing MCP (Model Context Protocol) servers across your organization.

• Authentication — Single auth layer at the gateway. Users authenticate once; your MCP servers receive verified requests
• Access Control — Control which teams and users can access which servers and tools. Revoke access instantly
• Observability — Every tool call logged with full context: who called what, parameters, response, latency
• Identity Forwarding — Forward user identity (email, team, roles) to MCP servers automatically

Works with Claude Desktop, Cursor, VS Code, and any MCP-compatible client. Get started →

Core Features

Reliable Routing

• Fallbacks: Fallback to another provider or model on failed requests using the LLM gateway. You can specify the errors on which to trigger the fallback. Improves reliability of your application.
• Automatic Retries: Automatically retry failed requests up to 5 times. An exponential backoff strategy spaces out retry attempts to prevent network overload.
• Load Balancing: Distribute LLM requests across multiple API keys or AI providers with weights to ensure high availability and optimal performance.
• Request Timeouts: Manage unruly LLMs & latencies by setting up granular request timeouts, allowing automatic termination of requests that exceed a specified duration.
• Multi-modal LLM Gateway: Call vision, audio (text-to-speech & speech-to-text), and image generation models from multiple providers — all using the familiar OpenAI signature
• Realtime APIs: Call realtime APIs launched by OpenAI through the integrate websockets server.

Security & Accuracy

• Guardrails: Verify your LLM inputs and outputs to adhere to your specified checks. Choose from the 40+ pre-built guardrails to ensure compliance with security and accuracy standards. You can bring your own guardrails or choose from our many partners.
• Secure Key Management: Use your own keys or generate virtual keys on the fly.
• Role-based access control: Granular access control for your users, workspaces and API keys.
• Compliance & Data Privacy: The AI gateway is SOC2, HIPAA, GDPR, and CCPA compliant.

Cost Management

• Smart caching: Cache responses from LLMs to reduce costs and improve latency. Supports simple and semantic* caching.
• Usage analytics: Monitor and analyze your AI and LLM usage, including request volume, latency, costs and error rates.
• Provider optimization*: Automatically switch to the most cost-effective provider based on usage patterns and pricing models.

Collaboration & Workflows

• Agents Support: Seamlessly integrate with popular agent frameworks to build complex AI applications. The gateway seamlessly integrates with Autogen, CrewAI, LangChain, LlamaIndex, Phidata, Control Flow, and even Custom Agents.
• Prompt Template Management*: Create, manage and version your prompt templates collaboratively through a universal prompt playground.
