Table of Contents
OpenAI has this week launched GPT-5.1, a meaningful update too its ChatGPT platform designed to address user feedback regarding the previous model’s perceived impersonality and brevity. The new iteration, arriving just three months after the release of GPT-5, promises a more bright, welcoming, and adaptable assistant, signaling a shift towards a more balanced approach between efficiency and user experience.
The update comes as OpenAI continues to refine its leading-edge artificial intelligence offerings, responding directly to concerns raised by a growing user base. According to reports from tek.sapo.pt, the GPT-5.1 model is already available to users, even in the free version, despite initial plans for a phased rollout limited to paid subscription tiers.
Two Models for Diverse Needs: Instant and thinking
GPT-5.1 arrives in two distinct variants, each tailored to different user preferences and task requirements. The GPT-5.1 Instant model is described by the company as “more welcoming, more intelligent and better at following instructions” than its predecessor. Conversely, GPT-5.1 Thinking excels in understanding and speed for simpler tasks, while demonstrating increased persistence when tackling complex challenges.
ChatGPT will, by default, intelligently select the most appropriate model based on the user’s query. Though, users retain the ability to manually choose their preferred model, offering a degree of customization previously unavailable.
Expanded Personality Options for a More Personalized Experience
Beyond the core model selection, OpenAI is also expanding the range of available personalities for chatgpt interactions. The existing options – “Default,” “Cynic” (sarcasm), “friendly” (formerly Listener), “Efficient” (formerly Robot), and “Nerd” (geek) – are being joined by three new additions: “Professional,” “Candid” (frank), and “Quirky” (eccentric). this expanded palette of personalities allows users to tailor the assistant’s tone and style to better suit their individual preferences and the context of the conversation.
Fine-Tuning Control and Future Updates
OpenAI is also preparing to test more granular controls over response formatting with a limited group of users. These controls will allow for adjustments to parameters such as simplicity, readability, and even the inclusion of emojis. the system itself may proactively suggest these adjustments during conversations, further enhancing the user experience.
While the initial rollout prioritizes subscribers to Business, Pro, Plus, and the newly introduced Go plans, the Tek Notícias team confirmed the availability of GPT-5.1 in the free version,demonstrating OpenAI’s commitment to broad accessibility. The company plans to eventually migrate all users from the original GPT-5 model to the new GPT-5.1.
