What DeepSeek does in game development
- Asset creation: generate 3D models, textures, sprites, icons and UI from text, a sketch or your own art, in the style of the game
- Animation: have poses, in-betweens and physically accurate movements calculated, and convert video to motion capture
- Characters and dialogue: NPCs with backstory, memory and voice that respond to the player in real time
- Testing and prototyping: have AI agents playtest builds and report bugs, and build playable prototypes with an AI assistant in the engine
- Very low API costs
- Open weights (MIT), self-hostable
- Strong at reasoning, maths and code
- Large context window (1M tokens)
DeepSeek has a specific GDPR concern. The DeepSeek service stores personal data in China and was blocked by the Italian regulator in 2025 January. Not advised for regulated sectors unless you host the model yourself within the EU. Weigh this heavily before using it in game development.
Confidentiality and GDPR
GDPR: CautionCheck per subscription what happens to your assets and prompts. Meshy and Convai may use your input and output to improve or train their services on standard plans (with Meshy you can opt out via support), Scenario does this on self-serve plans too and only contractually excludes it on Enterprise, and Ludo.ai reserves the right to train in its terms. On the free plan of Meshy, Meshy owns the output (use under CC BY 4.0 with attribution). Kaedim says it does not use your IP for training and is ISO 27001-certified, Cascadeur runs the AI tools locally and does not collect your animations as training data, and with Unity, training on your content is off by default. Most generative services store data in the US. Only put unreleased art, scripts or player data into a tool once a data processing agreement is in place, and for AI NPCs, check what the model might say to underage players.
The DeepSeek service stores data in China and uses it for training by default (with an opt-out). Only an EU self-hosted variant of the open weights is defensible for sensitive data.
