Imagine controlling a video game where the graphics, gameplay, and environment aren’t rendered by a traditional engine but generated in real time by artificial intelligence. That’s exactly what Microsoft has made possible with WHAMM.


WHAMM, short for World and Human Action MaskGIT Model, is the latest innovation from Microsoft’s Copilot Labs. Building upon the earlier WHAM architecture and the Muse family of world models, WHAMM allows for real-time interaction within a fully AI-generated environment starting with Quake II.


Let’s unpack this leap forward in interactive AI.


From Tokens to Gameplay: How WHAMM Works


WHAMM differs from its predecessor by doing one thing exceptionally well: speed. Where WHAM generated a single image per second, WHAMM hits over 10 frames per second, enabling responsive, real-time gameplay powered by a generative model.

Instead of using the traditional autoregressive model (generating one token at a time), WHAMM adopts a MaskGIT architecture, which allows multiple image tokens to be predicted in parallel and refined iteratively—creating a playable simulation of a fast-paced FPS.


This isn’t just AI rendering graphics. It’s AI understanding context, predicting outcomes, and simulating reactions based on user input in real time.


Training Smarter, Not Harder


WHAMM’s improvements weren’t just technical—they were strategic. Microsoft trained this model on just one week of curated Quake II gameplay data, a massive reduction from the seven years of gameplay used for WHAM-1.6B.


This efficiency was achieved by working with professional testers and focusing on a single, diverse level. Microsoft also doubled the output resolution to 640×360, further enhancing the user experience.


Under the Hood: A Dual Transformer Setup


WHAMM’s architecture relies on two core modules:


  • The Backbone Transformer (~500M parameters): Processes nine previous image-action pairs and predicts the next image.

  • The Refinement Transformer (~250M parameters): Iteratively improves the initial prediction using a lightweight MaskGIT loop.


Together, they enable fluid gameplay that responds instantly to movement, camera angles, and even environmental interaction—like exploding barrels or discovering in-game secrets.


Quake II Inside an AI Mind


The most astonishing part? You can play inside the AI model. Walk, run, shoot, and explore the world that WHAMM generates in real time. It’s not a recorded simulation—it’s a dynamic, generative space that responds to your actions.


What’s more, WHAMM allows inserting objects into the scene and watching them integrate naturally into the gameplay, opening doors to editable, player-influenced environments inside AI simulations.


Limitations to Note


As groundbreaking as WHAMM is, it’s still a research prototype. Notable limitations include:


  • Fuzzy or unrealistic enemy interactions

  • Limited memory (about 0.9s of context)

  • Imperfect health/damage tracking

  • Single-level scope

  • Minor input latency in public demos


These aren’t bugs they’re glimpses of how far this tech can go. WHAMM isn’t trying to replace a game engine. It’s a preview of what AI-generated media could become.


Why This Matters


WHAMM represents more than a cool tech demo. It shows how AI can model and simulate reality with minimal training data, in real time, using intuitive control schemes.


Future applications could range from fully interactive narrative experiences to AI-assisted game design—or even education and simulation tools that learn and adapt as you interact.


This isn't about replicating Quake II. It's about the rise of playable models—AI-powered experiences that are built as you explore them.


Final Thought


Microsoft’s WHAMM is a powerful step toward the convergence of machine learning and interactive media. It reimagines the very idea of what a “game” can be, placing players not just inside a world, but inside a model capable of creating that world in real time.


And the most exciting part? This is just the beginning.
