How to Use OpenAI on Antbase
All OpenAI models are available through Antbase's unified OpenAI-compatible API. You can either route directly to a specific OpenAI model or let ANT's intelligent router automatically select the best model for your task.
python
from openai import OpenAI
client = OpenAI(
base_url="https://antbase.ai/v1",
api_key="your-ant-api-key",
)
# Let ANT auto-route (may use OpenAI if optimal)
response = client.chat.completions.create(
model="ant:auto",
messages=[{"role": "user", "content": "Hello!"}],
)
# Or route directly to a OpenAI model
response = client.chat.completions.create(
model="openai/gpt-5",
messages=[{"role": "user", "content": "Hello!"}],
)Why Use OpenAI Through Antbase?
- •No separate account needed — access OpenAI models instantly through your Antbase API key.
- •Intelligent routing — ANT automatically selects the best OpenAI model for each task, or falls over to another provider if OpenAI is slow or down.
- •Same token prices — Antbase charges zero markup on OpenAI token prices. You pay exactly what OpenAI charges.
- •Automatic failover — if OpenAI has an outage, your requests seamlessly route to an equivalent model on another provider.
