OpenAI made its family of GPT-5.6 models available to its app and API users globally at the start of July.
Since launch, users have had the choice of three model versions: Sol as the most powerful; Terra for mainstream use; and Luna as the fast, efficient option for everyday tasks.
Sol is the star
Named after the Latin word for sun, OpenAI initially positioned GPT‑5.6 Sol as inherently more cost-efficient and capable of getting “more useful work from every token”, with the company’s most robust safety stack ever released. The company announced stronger protection for higher-risk activities and sensitive cyber requests, and spent “multiple weeks finding weaknesses” to pressure-test the system against real-world attacks.
Yet for all that galvanization, developers appear to be most interested in GPT‑5.6 Sol’s core functionalities and problem-solving capabilities.
Dallas Fort Worth-based AI research & development leader at content automation platform company BlogBuster, Russell Twilligear tells The New Stack that he’s been using GPT‑5.6 Sol and drawing direct performance comparisons to results from Anthropic’s Claude Opus 5.
“Sol is doing a better job creating things for me and finding mistakes made by Anthropic’s models; it’s blowing my mind,” Twilligear says.
“I’m creating a massive nationwide database (USA) with over three million entries, and Sol keeps finding mistakes made by Opus and correcting them. So, I did a reversal of roles: I asked Sol to create the database and then asked Claude Opus 5 to check it, and it didn’t really find anything wrong (only super …
