Portkey provides a robust gateway to facilitate the integration of your locally hosted models through Ollama.
First, install the Gateway locally:
npx @portkey-ai/gateway
Then, connect to your local Ollama instance:
from portkey_ai import Portkey

portkey = Portkey(
    base_url="http://localhost:8787/v1",  # Your local Gateway
    provider="ollama",
    custom_host="http://localhost:11434"  # Your Ollama instance
)

response = portkey.chat.completions.create(
    model="llama3",
    messages=[{"role": "user", "content": "Hello!"}]
)

​
Integration Steps

1

Expose your Ollama API

Expose your Ollama API using a tunneling service like ngrok or make it publicly accessible. Skip this if you’re self-hosting the Gateway.For using Ollama with ngrok, here’s a useful guide:
ngrok http 11434 --host-header="localhost:11434"
2

Add to Model Catalog

  1. Go to Model Catalog → Add Provider
  2. Enable “Local/Privately hosted provider” toggle
  3. Select Ollama as the provider type
  4. Enter your Ollama URL in Custom Host: https://your-ollama.ngrok-free.app
  5. Name your provider (e.g., my-ollama)

Use in Your Application

from portkey_ai import Portkey

portkey = Portkey(
    api_key="PORTKEY_API_KEY",
    provider="@my-ollama"
)

response = portkey.chat.completions.create(
    model="llama3",
    messages=[{"role": "user", "content": "Hello!"}]
)

print(response.choices[0].message.content)
Or use custom host directly:
from portkey_ai import Portkey

portkey = Portkey(
    api_key="PORTKEY_API_KEY",
    provider="ollama",
    custom_host="https://your-ollama.ngrok-free.app"
)
Important: The custom_host / customHost parameter (your Ollama URL) should be passed without /v1 — Portkey handles the provider routing automatically. However, when using a local gateway, the base_url / baseURL parameter must include /v1 (e.g. http://localhost:8787/v1).
