Introduction

GPT-5.6 Sol is OpenAI's high-capability Sol tier for demanding reasoning, coding, and agent workflows.

On LumeAPI you call it through the standard OpenAI-compatible chat completions surface with model id `gpt-5.6-sol`.

Pricing is published as input/output per 1M tokens at 50% off the official list rate, so production teams can keep Sol-class quality without paying full list price.

Use it when answer quality and tool-calling reliability matter more than raw latency.
