The GPT-5.1 version by default has become more conversational. It &#8220;surprises people with its playfulness while remaining clear and helpful.&#8221;<\/p>\n<p>The instruction processing has been improved, enabling the neural network to follow requests more accurately and provide more stable, relevant responses.<\/p>\n<p>GPT-5.1 Instant features &#8220;adaptive thinking&#8221;\u2014it can decide when it needs to &#8220;think&#8221; before responding. <span data-descr=\"large language model\" class=\"old_tooltip\">LLM<\/span> shows significant improvements in mathematics and programming tests AIME 2025 and Codeforces, noted OpenAI.<\/p>\n<h2 class=\"wp-block-heading\">GPT-5.1 Thinking<\/h2>\n<p>The upgrade to GPT-5 Thinking has made the model more efficient and understandable in everyday use.

Users will be able to compare the performance of new and old solutions and adapt to changes.<\/p>\n<p>In the future, the company will give people &#8220;enough time&#8221; to evaluate changes and provide feedback. Periods for discontinuing support for old neural networks will be announced in advance.<\/p>\n<h2 class=\"wp-block-heading\">Tone and Style Settings<\/h2>\n<p>Additionally, OpenAI has simplified the tone and style settings for ChatGPT.<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>&#8220;People have strong and diverse preferences about how ChatGPT should respond, and setting its tone to suit you should be easy,&#8221; the company believes.<\/p>\n<\/blockquote>\n<p>The options &#8220;Default,&#8221; &#8220;Friendly,&#8221; and &#8220;Efficient&#8221; remain, with &#8220;Professional,&#8221; &#8220;Candid,&#8221; and &#8220;Unusual&#8221; added.<\/p>\n<p>The new styles are designed with how users practically interact with the model in mind.<\/p>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/forklog.com\/wp-content\/uploads\/img-b86168d97c55050a-9413990099122576-1024x576.png\" alt=\"image\" class=\"wp-image-269595\" srcset=\"https:\/\/forklog.com\/wp-content\/uploads\/img-b86168d97c55050a-9413990099122576-1024x576.png 1024w, https:\/\/forklog.com\/wp-content\/uploads\/img-b86168d97c55050a-9413990099122576-300x169.png 300w, https:\/\/forklog.com\/wp-content\/uploads\/img-b86168d97c55050a-9413990099122576-768x432.png 768w, https:\/\/forklog.com\/wp-content\/uploads\/img-b86168d97c55050a-9413990099122576-1536x864.png 1536w, https:\/\/forklog.com\/wp-content\/uploads\/img-b86168d97c55050a-9413990099122576.png 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Choosing ChatGPT tone.
