What should I watch out for with AI in game development?

Check 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.

26 October 2026Cloudflare Workers AI: GLM-5.3 leaked 155 answers between customers

Cloudflare reported that GLM-5.3 on Workers AI (@cf/zai-org/glm-5.3) returned data from other customers' requests in 27 answers between 9 August and 2026 September 155. Only prompts above 681,280 tokens were affected; the cause was a KV cache that was too small in the hosting configuration, not the model itself. Cloudflare found no evidence of misuse and fixed it on 9 September. If you used very long prompts containing personal data via Workers AI in that period, assess whether a data breach has occurred. source
