GPT-5.6 Sol

openai/gpt-5.6-sol

GPT-5.6 Sol is the flagship entry of the GPT-5.6 family in OpenRouter’s catalog. Its stated focus is complex reasoning, command-line coding and multi-step problem solving, with text, image and file inputs listed in the reference.

Choosing this model

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

Where to start

Use it as a candidate for repository-level debugging where commands and tests supply feedback. Provide a bounded task, permitted tools and a requirement to report evidence for the final change.

What to watch for

Choosing the model does not provide a terminal, web search or filesystem. Those belong to the surrounding application. Do not import claims about a hosted agent product into the capabilities of this text request.

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.

Estimate your cost

Estimated credit consumed
$20.00
Estimated cash equivalent
$2.00

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.

Use the API

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

Tests pass locally but fail in CI with a case-sensitive import error. Give a diagnosis, a minimal fix and a check that prevents recurrence.

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

Look for a case mismatch in file paths and imports, not a recommendation to disable checks. Verify the fix on a case-sensitive filesystem and include a CI check.

Before you choose

Is this an OpenAI-hosted API endpoint?

No. This page documents the Y-API gateway and its exact catalog ID. OpenRouter supplies reference model information; neither that reference nor the name makes the gateway an official OpenAI endpoint.

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.
