Good morning, AI enthusiasts. OpenAI just released o3 and o4-mini, two new reasoning models that president Greg Brockman called a “GPT-4 level qualitative step into the future.”

With o3 pushing SOTA across all benchmarks and supposedly capable of creating new scientific ideas, is this the leap that finally puts the AI world at AGI’s doorstep?


In today’s AI rundown:

  • OpenAI’s o3 and o4-mini, new coding agent

  • Copilot gets hands-on computer use

  • How to run AI privately on your own computer

  • Claude gains autonomous research powers

  • 4 new AI tools & 4 job opportunities

The Rundown: OpenAI just released o3 and o4-mini, its smartest reasoning models yet that are now equipped with full agentic access to all ChatGPT tools and the ability to "think with images” — alongside the launch of a new open-source coding agent.

The details:

  • OpenAI o3 is the new top-tier reasoner, pushing SOTA performance across coding, math, science, and multimodal benchmarks.

  • o4-mini offers fast, cost-efficient reasoning, significantly outperforming previous mini models and even saturating benchmarks like AIME 2025 math.

  • Both models can use and combine all tools within ChatGPT (web search, Python, image generation, etc.) as part of their problem-solving process.

  • The models are also the first to be able to "think with images", integrating visual analysis and manipulation directly into their chain of thought.

  • Also launching is Codex CLI, an open-source coding agent that runs in users’ terminals and links reasoning models with coding tasks.

  • President Greg Brockman said the release is a “GPT-4 level qualitative step into the future,” with the models capable of producing novel scientific ideas.

Why it matters: Whatever the bar for AGI is, it feels like the latest SOTA models are getting close. While reasoners were already a massive leap, equipping them with access to tools and multimodal capabilities has led to a class of models that is creating new ideas — seemingly taking us to Step 4 of OpenAI’s ladder of AI intelligence.

MICROSOFT

🖥️ Copilot gets hands-on computer use

The Rundown: Microsoft just rolled out a new 'computer use' capability in Copilot Studio, enabling users and businesses to build AI agents that can directly operate websites and desktop applications.

The details:

  • The new feature allows agents to interact with graphical user interfaces (GUIs) by clicking buttons, selecting menus, and typing into fields.

  • The process unlocks automation for tasks on systems lacking dedicated APIs, allowing agents to use apps just like humans would.

  • Computer Use also adapts in real-time to interface changes using built-in reasoning, automatically fixing issues to keep flows from breaking.

  • All processing happens on Microsoft-hosted infrastructure, with enterprise data explicitly excluded from model training.

Why it matters: Copilot joins the likes of OpenAI and Anthropic’s Computer Use tools, marking another step in AI’s agentic shift from chat windows into everyday software. While it’s not the only UI automation tool, Microsoft users’ existing business workflows are a perfect use case to take advantage of this type of feature.

AI TRAINING

🤖 How to run AI privately on your own computer

The Rundown: In this tutorial, you will learn how to run powerful AI models directly on your own computer for complete privacy, zero cost, and offline use—without sending data to external servers.

Step-by-step:

  1. Choose your platform by downloading Ollama or LM Studio based on your command-line or GUI interface preference.

  2. Install the software and open it (both options are available for Windows, Mac, and Linux).

  3. Download an AI model that's suitable for your computer

  4. Start chatting with your AI using terminal commands in Ollama or the chat interface in LM Studio.

Pro tip: Match the model size to your computer's capabilities; newer computers might be able to handle larger models (12-14B), while older ones should stick with smaller models (7B or less).

ANTHROPIC

🔍 Claude gains autonomous research powers

The Rundown: Anthropic just unveiled major upgrades to Claude, introducing autonomous research capabilities and Google Workspace integration to allow the assistant to search both the web and user files for answers with better context.

The details:

  • The new Research feature can autonomously perform searches across the web and users’ connected work data, providing comprehensive, cited answers.

  • A new Google Workspace integration lets Claude securely access user emails, calendars, and docs for context-aware assistance without manual uploads.

  • Enterprise customers also get access to enhanced document cataloging, using RAG to search entire document repositories and lengthy files.

  • Research is launching in beta for Max, Team, and Enterprise plans across the US, Japan, and Brazil, with Workspace integration available to all paid users.

Why it matters: Anthropic continues to move at its own pace when it comes to feature rollouts, giving Claude a “Deep Research” type feature well after the other major labs. But as we’ve seen with other rivals, the combination of web search, user data integration, and SOTA models can lead to some extremely powerful results.
