Chat GPT is going to be faster and more interactive Open Eye Upgrades it Flagship model GPT5 to GPT-5.1.
Open Eye announced Two updates in the GPT 5 series: GPT 5.1 Instant and GPT 5.1 Think. Both models are now accessible on chatgpt.
GPT-5.1 Instant, essentially the default and most used model, is now “hotter, more intelligent and better at following your instructions,” according to OpenEye. Meanwhile, GPT-5.1 thinking is an advanced reasoning model that responds faster to simple tasks and more consistently to complex tasks.
“We heard clearly from users that great AI should not only be smart, but also fun to talk to,” Openei said in a statement. Blog post. “GPT-5.1 makes significant improvements on both intelligence and communication styles.”
The company added that both models offer users a way to “shape the tone of Chatput,” allowing people to control how the chat platform responds to their conversations.
Both models were designed for ChatGPT Pro, Plus, GO and Business users, as well as the Free tier. Those on Enterprise and EDU plans will get seven days of early access toggles for models before GPT-5.1 becomes the default model. Models can also be accessible through an API, both with adaptive logic, Openei said.
OpenEye has noted that it will soon update GPT5 Pro to version 5.1.
Quick and thoughtful models
tHe 5.1 reflects improvements in tag-base models, and considers them part of the OpenGPT5 family, which is trained on the same stack and data as its inference models. The biggest difference between OpenGCEO 5.1 and 5 for applications is its more natural and conversational tone. Post.
“Based on early testing, it often surprises people with its playfulness while remaining clear and useful,” Openai said in his post.
Can quickly use adaptive reasoning to help him make decisions when he needs to think about his answers, especially when it comes to more complex questions. OpenEye notes that it has improved the model’s directive following, so that while it continues to respond quickly, it also directly addresses the user’s query.
Recent model releases, eg Bedouin‘ERNIE-4.5-VL-28B-A3B-THINKING, is Optimizing GPT-5 In a benchmark such as instruction following.
GPT. It adapts to the type and complexity of a question, so a full, complex question will take longer to answer than a simple summary request.
Evaluations show that GPT-5.1 thinking spends less time and therefore uses fewer tokens on simple tasks than GPT5, improving the base model in response speed, Openei said.
One thing enterprises should note is that GPT-5.1 answers to thinking “with less jargon and less undefined terms.” When it comes to explaining technical concepts, eliminating the jargony response makes thinking more accessible, Oppani said.
More personalization
Another big update for ChatGPT is the increase in personalization. This allows users to toggle between a friendly and authentic chat platform experience in their conversations.
ChatGPT already allows users to choose preset options for model tones, but the new update expands those options “to better reflect the common ways people use ChatGPT.”
Ohptions include "default," "friendly" (First "The listener", "effective" (First "Robot", "professional," "clear" And "Quirky" Two other figures, "Reprobate" And "nervous," No change.
“We think many people will find that the GPT-5.1 does a better job of combining IQ and EQ, but a default obviously won’t meet everyone’s needs," Simo said. "That’s why we’re making it easy to customize ChatGPT with multiple presets to choose from. The model has the same capabilities whether you choose the default or one of these options, but the response style will be different – more formal or familiar, more playful or direct, more or less jargon or slang. Of course, the eight personalities still don’t cover the full range of human diversity, but we know from our research that many people prefer simple, guided control over many settings or open-ended options."
People can also adjust how much ChatGPT uses emojis. Openai offers granular control for the response and is experimenting with the ability to make the model more compact, warm or scannable.
A rollout saving
Openai’s GPT 5 rollout was…Less than perfect. While company executives, including CEO Sam Altman, touted the new model’s capabilities, the decision to sunset the old and beloved model initially met with dissatisfaction on ChatGPT. Worse, many early adopters found that GPT5 performed no better than older options in domains like math, science, and writing.
This led Altman to walk back some of his statements surrounding the removal of the model, blaming performance issues on the GPT5’s router. The router, which automatically directs queries to the most appropriate models, is not going away, as GPT-5.1 auto-models indicate the type of model that can best answer queries.
Openai is careful to note that GPT5 models Quick, Think and Pro are still available in ChatGPT’s model dropdown, although paid users only have three months to compare these older versions with the 5.1 update. The sunset period for the GPT-5, however, will not affect models like the GPT-4O.
“Going forward, as we introduce new ChatGPT models, our approach is to provide ample space for people to evaluate what has changed and by sharing feedback, allows us to continue to innovate our Frontier models during a smooth transition,” the company said. “Sunset periods will be communicated clearly and with sufficient advance notice.”
