OpenAI has started a pilot program for group chats on ChatGPT in four countries. These chats, accessible in Japan, New Zealand, South Korea, and Taiwan, let multiple users interact with the AI simultaneously for collective tasks. The rollout requires access to the GPT-5.1 model, which was introduced earlier this week. This new feature is designed for activities like planning trips, researching projects, or choosing restaurants together, as explained in a recent blog post.
Throughout the year, OpenAI has rapidly introduced new products and updates to its AI systems. In February, ChatGPT rolled out Deep Research and the GPT-4.5 “Orion” model. This version was notable for delivering research-level output with citations, though some concerns arose about its ability to sort reliable sources from unreliable ones.
In April, OpenAI launched the o3 and o4-mini models focused on reasoning and step-by-step problem-solving. These changes marked the start of ChatGPT’s move from pure text generation to more agent-like AI assistance. May brought the GPT-4.1 model, which made code generation and debugging more dependable, benefiting software teams.
Significant changes followed in August with the debut of GPT-5, featuring multimodal functions and intelligence able to choose between quick or deep responses. The same month saw the introduction of ChatGPT Go, a cheaper subscription available for around $5 per month, less than the Plus plan at $20 per month. This lower price led to double the number of paid ChatGPT users in the initial rollout country.
Further advancements arrived in October and November with the release of Sora 2, a text-to-video tool delivering realistic scenes and synchronized audio. Mobile apps for this tool were also launched, with the iOS version briefly topping the Apple App Store. In November, OpenAI released GPT-5.1, updating its main model with a friendlier conversational tone and greater analytical detail.
