Overview

What is GPT 6 | Sol?

GPT 6 Sol is the cost-efficient high-end model of OpenAI’s GPT-6 series, released in September 2026. It sits below the flagship GPT 6 Astra and above GPT 6 Luna, the fast tier. OpenAI presents it as close to Astra in factual reliability at a much lower cost, with the same clear, concise style.

In Havincy, Sol is the everyday sweet spot: captions, scripts, post ideas, replies to comments or automating repetitive tasks. It reads text, images and files and has a context window of over one million tokens.
