Good morning, AI enthusiasts. One of the biggest gaming platforms in the world just made 3D content creation as simple as a text command — and its 85M daily users are about to build and monetize like never before.

Between Roblox’s new open-source Cube 3D model and other recent AI and coding upgrades, building the game of your dreams is suddenly just a few prompts away.

In today’s AI rundown:

  • Roblox’s open-source 3D generation AI

  • Zoom’s AI Companion goes agentic

  • Turn logos into ready-to-sell product mockups

  • Google’s AI satellite to spot wildfires early

  • 4 new AI tools & 4 job opportunities

LATEST DEVELOPMENTS

ROBLOX

The Rundown: Roblox just announced Cube 3D, a new open-source AI system for generating 3D objects and scenes from text prompts — alongside a slew of other tools and updates for AI-assisted game development.

The details:

  • Cube 3D generates complete, functional 3D objects from text prompts, training on native 3D data instead of traditional image-based reconstruction.

  • Developers can generate assets through simple commands like "/generate motorcycle," with image input capabilities also coming in the future.

  • Cube uses ‘3D tokenization’ to predict and generate shapes the same way language models predict text, enabling future 4D scene generation capabilities.

  • Roblox also released updates to its Studio content creation suite including improved performance, real-time collaboration features, and monetization tools.

Why it matters: Between ‘vibe-coding’, Gemini’s new native multimodal image capabilities, and open-source tools like Cube 3D, it has never been easier to take a game from idea to reality. With 85M+ daily active users, these AI tools will supercharge both Roblox’s growth and the ability for users to build and monetize on the platform.

ZOOM

The Rundown: Zoom announced a major upgrade to its AI Companion, introducing new agentic capabilities and skills that allow the assistant to identify and complete tasks across the platform’s ecosystem.

The details:

  • AI Companion is getting new memory and reasoning capabilities to problem-solve and leverage the correct agentic tools for each task.

  • Zoom Tasks automatically detects and executes action items from meetings, scheduling follow-ups, or generating documents without user intervention.

  • Other new features include calendar management, clip generation, writing assistance, voice recording transcriptions, and live notes for meetings.

  • A new $12/month Custom AI Companion add-on is also launching in April, offering personal AI coaches, AI avatars for video messages, and more.

Why it matters: Zoom pivoted in 2024 to be entirely ‘AI-first’, so it’s no surprise to see it now enter the agentic game with automated workflows and tasks on the platform. CEO Eric Yuan previously shared a vision of AI digital twins that can attend meetings in a user’s place, and April’s launch may be the first step towards that goal.

AI TRAINING

The Rundown: In this tutorial, you will learn how to use Recraft's mockup tool to place your brand logos directly onto product images for instant e-commerce and presentation visuals.

Step-by-step:

  1. Sign in to Recraft (free account includes 50 daily credits) and click anywhere on the blank canvas to begin.

  2. Select "Product Photo" and choose a preferred product template (like a t-shirt).

  3. Click "Import Image" to upload your logo to the canvas and click "Remove Background" to make it transparent.

  4. Drag your logo onto the product photo and watch as it automatically adapts to the fabric's contours.

Pro tip: You can try different placements on your product to find the most appealing position before finalizing your mockup.

PRESENTED BY INNOVATING WITH AI

The Rundown: Innovating with AI's new program, AI Consultancy Project, transforms AI enthusiasts into professional consultants — tapping into a market projected to reach $54.7B by 2032.

The 6-month program delivers:

  • Proven frameworks for client acquisition and service delivery

  • A step-by-step path to six-figure consulting income

  • Students who land their first AI client in as little as 3 days

GOOGLE

The Rundown: Google Research and Muon Space just launched the first AI-powered FireSat satellite, designed to provide powerful tools for early wildfire detection — with the ability to spot fires as small as a classroom within minutes of ignition.

The details:

  • Current wildfire detection relies on infrequently updated, low-resolution imagery that often can't spot fires until they've grown to several acres in size.

  • Using infrared sensors and AI analysis from space, FireSat can detect fires as small as 5x5 meters — dramatically smaller than current satellite systems.

  • The satellite is the first of more than 50 planned for the entire FireSat constellation, which will scan nearly all of Earth's surface every 20 minutes.

  • When fully deployed, the system will create a global historical record of fire behavior to help scientists better understand and model wildfire patterns.

Why it matters: Wildfire seasons continue to intensify worldwide, and early detection can be the difference between a small containment and a catastrophic event. In addition to the wealth of real-time data being fed to emergency responders, FireSat’s data will also advance scientific understanding for more efficient firefighting.
