OpenAI: GPT-4o
OpenAI GPT-4o API pricing
GPT-4o costs $1.00 per million input tokens and $4.00 per million output tokens on Oxyy. These are the pay-as-you-go prices after the current 60% discount (Launch Promo; standard price $2.50 input and $10.00 output), and cached input tokens are billed at $0.500 per million. It accepts text and images and returns text, with a 128K-token context window and up to 16K output tokens per response. A cheaper OpenAI option is GPT-6 Sol at $0.800 / $4.00 per 1M tokens; for every model and rate, see OpenAI API pricing.
Providers
Where this model runs, and what each route costs. Requests are sent to a healthy provider automatically; if one errors, the gateway retries against another serving the same model.
| Provider | Input /M | Output /M | Cache read /M |
|---|---|---|---|
| OpenAI | $1.00 | $4.00 | $0.500 |

Supported parameters (2)
A parameter not listed here may be removed before the request reaches the model. When it is, the request still succeeds and the response names it, with the reason, in provider_specific_fields.dropped_params.
Pricing
What this model costs on Oxyy, pay as you go. "Charged" is the rate a request is billed at; the standard price is shown beside it for reference.

Quickstart
Call gpt-4o with a POST to /v1/chat/completions on https://api.oxyy.ai, using your Oxyy API key from the OXYY_API_KEY environment variable. The same key works for every model in the catalog.
import os
from openai import OpenAI
client = OpenAI(
base_url="https://api.oxyy.ai/v1",
api_key=os.environ["OXYY_API_KEY"],
)
response = client.chat.completions.create(
model="gpt-4o",
messages=[
{"role": "user", "content": "Explain unified AI APIs in one sentence."},
],
)
print(response.choices[0].message.content)Availability
The share of requests to this model that completed successfully over the last 30 days. Requests the caller cancelled, and requests still in flight, are not counted. When an upstream provider errors, the gateway retries against another provider serving the same model, so a single provider incident does not necessarily show up here.
Days are UTC days. Days with no completed requests are omitted rather than drawn at 100% — no traffic is not evidence of availability.
Activity
Token volume and request traffic to this model over time. Daily totals, UTC.
Prompt tokens measure input size. Completion tokens reflect total output length. Reasoning is not priced separately for this model, so it is not itemised here.
