Choosing this model
Selection advice by Y-API. The checks below are suggested evaluations, not published test results.
Where to start
Try it on a problem that has an objective answer you can verify — a failing proof, a numerical method that loses precision, a multi-file bug — rather than on open-ended writing.
What to watch for
Flagship positioning is the publisher’s framing, not a benchmark result on this page. The listed window is the model’s, not a promise that a 1M-token request will be accepted end to end through the gateway.
Model specifications
These are OpenRouter model-level specifications, not a Y-API compatibility test. A particular route may accept fewer input formats, parameters or tokens. Verify the features you need with a small request; a successful text response does not validate vision or tool calling.

API pricing & cost estimate
- Estimated credit consumed
- $14.00
- Estimated cash equivalent
- $1.40
Illustrative token budget, not measured usage or a quote. Includes input and output; excludes separate media charges, cache discounts and retries. Include billed reasoning tokens in your output budget where applicable. Actual billing follows usage returned by the service.
$1 paid adds $10 of credit. Cash equivalent = credit consumed ÷ 10; this is not the model publisher’s list price.
| Model | Estimated credit consumed | Estimated cash equivalent |
|---|---|---|
| Gemini 4 Argon | $14.00 | $1.40 |
| Gemini 3.1 Pro Preview | $9.50 | $0.95 |
| GPT-6 Astra | $35.00 | $3.50 |
API integration examples
These minimal, text-only requests use the exact Y-API model ID. They do not demonstrate image, audio, video, file or tool support. The output limit also needs room for reasoning; an empty answer with finish_reason=length can mean the budget was exhausted.
A task to try
This integration test fails only when the suite runs in parallel. Give the most likely shared-state cause, the smallest change that removes it, and a command that reproduces the failure before the fix.
Set the TOKEN environment variable to a key from your console. Run this on your server or locally; never expose a key in browser code or a public repository.

JSONHow to evaluate the result
The proposed reproduction should actually fail before the change and pass after it. A diagnosis that cannot be reproduced is a hypothesis, not a fix.
Before you choose
Does the multimodal input list mean I can send video?
The specification lists video input, but gateway forwarding is a separate fact. Test one small video request and check the response before you depend on it in a product.
Sources & scope
Technical facts come from the cited model page and, where available, its linked publisher card. A card describes that checkpoint; it is not proof of the weights a gateway serves. Prices come only from the Y-API catalog. We do not claim measured latency, uptime or benchmark scores for this endpoint.
