OpenAI has run simultaneous A/B tests on updated text and image models inside ChatGPT in recent days. The tests reference GPT-5.5 as the current model and version 5.6 as the next candidate. Google plans to release AI model 3.2 this week. OpenAI has previously launched models shortly after major Google releases, with GPT-5.6 positioned as a potential follow-up.

I love GPT-5.5. It's a workhorse and exactly the model I was hoping for. But the fact that rumors say version 5.6 is already in the starting blocks makes me even more excited! OpenAI is on fire.

Big week for AI

Google is dropping 3.2 and it’s a pretty good model

Historically OpenAI has countered with their own launch - GPT 5.6 may land as well
