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?

Quickstart (2 mins)

1. Setup your AI Gateway

# Run the gateway locally (needs Node.js and npm)
npx @portkey-ai/gateway
Deployment guides:   Portkey Cloud (Recommended)   Docker   Node.js   Cloudflare   Replit   Others...

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..

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.

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

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

* Available in hosted and enterprise versions
