ChatGPT 5.1 is here

🔍 AI Idea of the Week: ChatGPT 5.1 Just Dropped ​​

Big news: ChatGPT 5.1 just launched. 🤩

OpenAI says the new version is “warmer,” more conversational, and much better at following instructions, closer to the natural feel people loved in GPT-4o.

The model is faster on easy tasks and more consistent on complex reasoning or multi-step work.

This update also includes expanded personality options in Settings → Personalization.

The update is rolling out to paid users this week, with free users getting access later.

🛠 AI Tool We’re Testing: Learn Your Way (Google)

Learn Your Way is Google’s personalised learning tool that can rewrite textbooks, PDFs, and even complex technical documents based on your interests. 

If you prefer gaming analogies, it might explain an AI concept through controller setups or game mechanics. If you’re into music, it can connect ideas to production, rhythm, or sound design. The goal is simple: make difficult material easier to understand by linking it to something you already enjoy.

The tool also turns each lesson into multiple formats, including audio lessons, interactive quizzes, mind maps, and custom illustrations, so you can learn in the style that works best for you.

It’s free to try while in beta, and a strong early look at where personalised learning is heading.

Thanks for reading, have an amazing week ahead. 🚀

Best,
