Tarseek sits between your code and model providers. You keep the SDK; we make the routing decision.

Pass the exact Public model ID in your request and configure project-level model or provider restrictions.

Tarseek picks the route

Each request is matched with the best eligible, healthy deployment serving that exact model.

See what you saved

Every decision is visible in your request logs, with cost, latency, fallback details, and estimated savings.

OpenAI compatible

Change one URL. Keep your stack.

Use the SDK and request format you already know. Pass the exact Public model ID shown in the Models page; Tarseek selects its best eligible deployment.

Python

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.tarseek.com/v1",
    api_key=os.environ["TARSEEK_API_KEY"],
)

response = client.chat.completions.create(
    model="openai/gpt-4.1-mini",
    messages=messages,
)
