We’re making GPT-5 warmer and friendlier based on feedback that it felt too formal before. Changes are subtle, but ChatGPT should feel more approachable now.

You'll notice small, genuine touches like “Good question” or “Great start,” not flattery. Internal tests show no rise in sycophancy compared to the previous GPT-5 personality.

Changes may take up to a day to roll out, more updates soon.

Introducing shopping research, a new experience in ChatGPT that does the research to help you find the right products.

It’s everything you like about deep research but with an interactive interface to help you make smarter purchasing decisions.
Shopping research asks smart clarifying questions, researches deeply across the internet, reviews quality sources, and builds on ChatGPT’s understanding of you from past conversations and memory to deliver a personalized buyer’s guide in minutes.

openai.com/index/chatgpt-…
With shopping research, ChatGPT learns what you like as you shop.

You can guide the results by marketing suggested items as “Not interested” or “More like this.”

This allows the research to adapt based on your real-time feedback.

We’ve developed a new way to train small AI models with internal mechanisms that are easier for humans to understand.

Language models like the ones behind ChatGPT have complex, sometimes surprising structures, and we don’t yet fully understand how they work.

This approach helps us begin to close that gap.
openai.com/index/understa…
Most neural networks today are dense and highly entangled, making it difficult to understand what each part is doing.

In our new research, we train “sparse” models—with fewer, simpler connections between neurons—to see whether their computations become easier to understand.
Unlike with normal models, we often find that we can pull out simple, understandable parts of our sparse models that perform specific tasks, such as ending strings correctly in code or tracking variable types.

We also show promising early signs that our method could potentially scale to understand more complex behaviors.

GPT-5.1 in ChatGPT is rolling out to all users this week.

It’s smarter, more reliable, and a lot more conversational.

openai.com/index/gpt-5-1
GPT-5.1 is now better at:

- Following custom instructions
- Using reasoning for more accurate responses
- And just better at chatting overall
GPT-5.1 Instant is now warmer and more conversational.

The model can use adaptive reasoning to decide to think a bit longer before responding to tougher questions.

It also has improved instruction following, so the model more reliably answers the question you actually asked. Image

Today we’re introducing GDPval, a new evaluation that measures AI on real-world, economically valuable tasks.

Evals ground progress in evidence instead of speculation and help track how AI improves at the kind of work that matters most.
