How People Are Using AI For Developing Games

We just launched Claude Sonnet 4.5 and “Imagine with Claude”, a 5-day preview that creates dynamic experiences for you in real-time (and the first product I’ve worked on at Anthropic!). It pioneers the concept of “model-as-backend”, using a model to not only generate interfaces on the fly but also power all the functionality behind it – all made possible by our newest model, Claude Sonnet 4.5. Here’s a "choose your own adventure" version of my founder journey, as retold by Imagine with Claude:

Meet https://t.co/X8NRTZ8C7X — the world’s first vibe coding game agent. 1️⃣ From months of coding in engines → now one prompt builds a full game. 2️⃣ All assets — characters, maps, music, sound effects, animation — are AI-generated and auto-organized. 3️⃣ Built-in ads & map editor are on the way — making creation and monetization even easier

2023 was the year of AI avatars 2024 was the year of AI photos 2025 was the year of AI videos And I think it's becoming clear now that 2026 will be the year of AI world models Fully interactive explorable 3d worlds generated from one or multiple 2d images or a prompt In turn these 2d images can then be generated by AI too So soon you can generate fully explorable virtual 3d worlds based on your own imagination Next will be figuring out how to make those worlds interactive This is @theworldlabs (unaffiliated, but I like it) As always a lot of big AI model companies are now working on the same thing: 3d world models, only World Labs has a real properly working demo (for now) Very exciting time again!

Generated 3D worlds aren't just for viewing, you can also play projectile jenga inside link below https://t.co/d1G5fvGrZ3

Generate persistent 3D worlds from a single image, bigger and better than ever! We’re excited to share our latest results and invite you to try out our world generation model in a limited beta preview. https://t.co/HkPO4E5X2g

NeRFs & 3DGS look great but are static. Veo/Genie show how exciting dynamic worlds can be. What if we brought that dynamism into explicit 3D? ✨ Meet Pixie: a feed-forward “Physics from Pixels” model — simulatable, fast, and generalizable 👇🧵 🌐 https://t.co/2HrsbqPHED

Introducing Mirage 2 — a real-time, general-domain generative world engine you can play online Upload any image—photos, concept art, classic paintings, kids' drawings—and step into it as a live, interactive world. Prompt your worlds with text to create any surreal scenes and wild events. Then share a link—your friends can jump in and play instantly. 👉 Playable link and demos below in the thread

Matrix-Game 2.0 — The FIRST open-source, real-time, long-sequence interactive world model Last week, DeepMind's Genie 3 shook the AI world with real-time interactive world models. But... it wasn't open-sourced. Today, Matrix-Game 2.0 changed the game. 🚀 25FPS. Minutes-long interaction. Fully open-source.

Introducing Genie 3, our state-of-the-art world model that generates interactive worlds from text, enabling real-time interaction at 24 fps with minutes-long consistency at 720p. 🧵👇 https://t.co/ew3JoEAsLG

A few researchers at Anthropic have, over the past year, had a part-time obsession with a peculiar problem. Can Claude play Pokémon? A thread: https://t.co/K8SkNXCxYJ
