Choosing this model

Selection advice by Y-API. The checks below are suggested evaluations, not published test results.

Where to start

Use it as the workhorse for professional tasks that are too involved for a Lite tier but do not need the flagship: code review, structured extraction from long documents, multi-step tool use.

What to watch for

It shares a price point with GPT-5.6 Sol in this catalog, so the generation number alone does not tell you which is the better buy. Compare on your own tasks instead of assuming the newer entry wins.

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
$7.00
Estimated cash equivalent
$0.70

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.

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

Extract every obligation from this contract into a table with party, action, deadline and penalty. Mark any clause whose deadline is relative rather than fixed.

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.

How to evaluate the result

Check the relative deadlines — “within 30 days of notice” is not a date. A table that fills in a calendar date for a relative clause has invented information.

Before you choose

Does GPT-6 Sol replace GPT-5.6 Sol?

No — both remain separate catalog entries. They are close in price, so the choice should come from a head-to-head run on your tasks, not from the version number.

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.
