DeepSeek-V4-Flash-Vision-Exp is amazing at creating game worlds!

• Model: DeepSeek-V4-Flash-Vision-Exp (local and API when impatient)
• Time: about one weekend (2 days) of QA and small improvements
• Full game is here

After Qwen3.8-Flash-Next one-shotted a really cool Cat-Hunt game demo, I decided to see what the new DeepSeek vision model can do.

Now that it has vision, DeepSeek-V4-Flash is able to take game screenshots, allowing it to:

• Generate and correct game models and textures until they look right
• Fix any visual artifacts or glitches
• Write scripts to take sequences of screenshots for animations and correct animations
• Generally play-test the game, including UI and game mechanics

The results are incredible, I was able to create a compelling game world in just a couple of days!

Edit: I noticed the game was slow on a laptop, so I added some performance improvements - let me know if you still find it too slow!

Edit: Some more info to answer common questions

• Custom engine on top of three.js
• 6800 lines of code for everything - models, textures, animations, sounds, effects, shaders, and all the game logic
