OpenAI’s New Reasoning Models: o3 and o4-mini

OpenAI just released o3 and o4-mini — not only the company’s most advanced reasoning models to date, but also the first to introduce visual understanding and full access to all ChatGPT tools.

Details:

• The o3 model is OpenAI's most advanced reasoning model to date, outperforming previous models in math, coding, reasoning, science, and visual understanding. Meanwhile, o4-mini is a smaller, cheaper, and faster model.

• Unlike previous reasoning models, o3 and o4-mini can use all ChatGPT tools, including web browsing, Python, image understanding, and image generation, to better solve complex, multi-step problems — for example, finding the location of a restaurant based solely on a photo of the menu.

• Both models will also be the first to “think” with images, integrating them directly into their chain of thought.

• OpenAI has also launched Codex CLI, an open-source coding agent that runs locally in users' terminals. It is designed to provide users with a simple and clear way to connect AI models to their own code and tasks running on their computer.

The new models are already available for ChatGPT Plus, Pro, and Team users, replacing the previous o1, o3-mini, and o3-mini-high models. Meanwhile, free users can try o4-mini by selecting 'Think' in the composer before submitting their query, with rate limitations.

xAI Adds Memory Feature to Grok

xAI has introduced a new “memory” feature to its Grok chatbot, enhancing its ability to remember details from past conversations.

Details:

• This allows Grok to provide more personalized responses based on user interactions over time. For instance, if you've previously discussed your preferences with Grok, it can tailor future recommendations accordingly.

• The memory feature is currently available in beta on Grok.com and the Grok iOS and Android apps, though it's not yet accessible to users in the EU or U.K.

• Users have control over this feature; they can disable it via the Data Controls page in the settings menu and delete individual memories directly from the chat interface.

• xAI plans to extend this memory functionality to the Grok experience on X in the near future.

This new feature helps Grok catch up to competitors like ChatGPT, which recently upgraded its memory function, and Gemini, which offers similar capabilities. As companies continue to focus on personalization, "memory" is becoming a key feature in today’s leading AI models.
