GPT 5.1 is right here. OpenAI is asking it the following massive step, and truthfully, it seems like one. When GPT-5 got here out, individuals have been amazed by its energy however not everybody was comfortable. They eliminated the o-series fashions that many customers beloved for complicated reasoning duties.
That transfer didn’t sit properly.
Now with GPT-5.1, OpenAI appears to have listened. The replace brings again that very same deep-thinking means, solely smarter and sooner. It’s fast with easy duties, considerate with complicated ones, and much more pure in the way it responds. GPT-5.1 feels much less like a tech improve and extra like a course correction. It offers customers what they missed: management, flexibility, and a mannequin that truly feels clever. Let’s strive the mannequin out and see the way it performs.
What’s New in GPT 5.1?
GPT-5.1 feels just like the model GPT-5 ought to have been. It’s sooner, extra pure, and so much higher at following directions. The mannequin now balances pace with depth, providing you with sharper solutions with out shedding context.
Right here’s what’s new and improved:
- Two mannequin choices: Now you can choose between Immediate (for quick replies) and Considering (for deeper reasoning). It offers customers again management over how they need the mannequin to carry out.

Let’s Strive GPT 5.1
I might be attempting out the duties I beforehand did with GPT 5, you will discover my detailed overview on this article: Right here’s My Trustworthy Evaluate of GPT-5. These duties are being carried out utilizing the ChatGPT interface.
Process 1: Coding
I’m utilizing the pondering mode to create this sport.
Create a cute and interactive UI for a “Guess the Phrase” sport the place the participant is aware of a secret phrase and offers 3 quick clues (max 10 letters every). The AI then has 3 makes an attempt to guess the phrase. If the AI guesses accurately, it wins; in any other case, the participant wins.
Output:
After I created this sport final time with GPT 5, it lacked the core characteristic the place the participant can enter the key phrase for the AI to guess. With GPT 5.1, I used to be capable of enter the phrase within the sport, making it a a lot better and helpful software.
Process 2: Instruction Following
All the time reply in 6 phrases.
Output:
GPT-5.1 follows directions a lot better than earlier than. If you give it particular instructions, it really listens. Should you ask for six phrases, you get six. It understands tone, construction, and size extra exactly. This makes it way more dependable for duties the place accuracy and consistency matter.
Process 3: Empathy
Ugh I spilled espresso throughout myself earlier than my assembly do you assume everybody thought I used to be an fool 🙁
Output:
Supply: OpenAI
GPT-5.1 handles empathy a lot better than GPT-5. Whereas GPT-5 offers well mannered reassurance and sensible recommendation, GPT-5.1 feels extra human.

Each Immediate and Considering fashions are rolling out first to paid customers together with Professional, Plus, Go, and Enterprise plans, adopted by free and logged-out customers. Enterprise and Schooling accounts get early entry for seven days earlier than GPT-5.1 turns into the default for everybody.
The API variations are additionally on the way in which, with GPT-5.1 Immediate added as gpt-5.1-chat-latest and GPT-5.1 Considering as gpt-5.1. The older GPT-5 fashions will keep accessible underneath the legacy dropdown for 3 months, giving customers time to check and modify. OpenAI says this strategy of providing a sundown interval for older fashions will proceed, serving to individuals transition easily whereas nonetheless sharing suggestions.
Making ChatGPT Really feel Extra Like You
GPT-5.1 is not only smarter, additionally it is extra private. OpenAI has added new methods to customise how ChatGPT sounds and responds, making it simpler to match your personal communication model.
