by Polygoningenieur in Addons

What Blender Version do the AIs know?
  • OpenAI GPT-4o - Blender 3.6
  • Google Gemini 1.5 Pro - Blender 4.0 🎉
  • Anthropic Claude 3 Opus - Blender 3.6 Beta
Are there any costs?

Yes, when you use the large language models, you pay OpenAI, Google or Anthropic for it. Here are their plans and pricing:

For all my testing during development for over a year now, so far I only payed $15,66 in total, so it is very affordable.

For Google you even get a first time $280 credit!
