Muranyi-3 is here. It is the latest model from Tesana — our most powerful AI game model yet, and the biggest leap forward we have ever shipped in a single release.
If you have built a game with Tesana before, you already know how it feels: you describe what you want, and the AI builds a real, playable game for you. Muranyi-3 keeps that core experience and rebuilds nearly everything around it.
What is new
Built-in code editor
A full code editor is now baked right into the studio. Browse your game's files, open any script, make changes, and the agent picks up from where you left off — the best of both worlds, AI-driven generation when you want it and direct control when you need it.
Better animations
Characters in M3 finally move like characters. Smoother, more realistic motion across run cycles, attacks, idle poses — all of it reads as alive in a way previous versions struggled to nail.
Improved asset library
A rebuilt asset library lets you browse, preview, and manage every model, texture, and audio file in your game without leaving the studio. Faster, cleaner, built to scale as your project grows.
Smarter code generation
The model is meaningfully smarter at writing code. Games built with M3 are cleaner, more scalable, and more consistent — every prompt produces a slightly better starting point, and every follow-up edit lands cleanly on top.
Fewer bugs
Across thousands of games built on Tesana, we cataloged the bugs and crashes our model has produced. With Muranyi-3, 90% of the most common errors are solved before they ever ship.
Smaller game files
A new build pipeline ships dramatically smaller game files. Players open your games faster, downloads finish quicker, and your games feel snappier — even on slower connections.
Faster generation
Better games in less time. Muranyi-3 generates faster end-to-end than any previous version.
Available everywhere you already use Tesana
Muranyi-3 is live now — on the web at tesana.ai and on iPhone. There is nothing to upgrade, nothing to pay for. Open Tesana and you are already on M3.
Tesana desktop apps for macOS and Windows are coming soon.
