Perguntas frequentes
Who pays for the AI API costs?
The buyer pays all API usage costs. You will need to provide your own API key to get things running. I can guide your on setting up usage limits and monitoring so your costs are effective.
Which versions of Unity and Unreal Engine do you support?
I am fully up to date with Unity and Unreal Engine 5.1 - 5.4. If you are working with an older version or a custom engine branch, just shoot me a message before ordering so we can make sure everything integrates smoothly.
Is the AI logic optimized for Mobile or VR headsets?
Yes. Performance is huge priority for me. I use asynchronous programming and deep profiling to ensure the AI doesn't cause FPS drops and game runs smooth on Meta Quest and Mobile devices.
How do you keep my API key safe from Players?
I implement a secure AI bridge or backend handler so your secret keys are not hard coded into the game client which keeps your credits safe and protects API access.
Can we use local LLMs to avoid monthly API fees?
Yes we can! I can integrate local models like Llama 3 or Mistral that runs directly on the player's hardware.
Do I need to provide the 3D models and animations?
Yes please. I build the AI logic and technically link its decisions to your animations but you will need to provide the character assets and animation files for me to work with. If you don't have the assets and animations, you can contact me for a custom offer.
Will NPCs remember what the player said in past sessions?
Standard packages include per session memory. If you want them to remember names or events across different timelines, you can contact me for that.
