How it works

This workflow has no local model files. It uses the llm-toolkit custom nodes to send your photo and instructions to Gemini 2.5 Flash Image on OpenRouter.

The subject photo is loaded and passed through ResizeAndPadImage to the size from ResolutionSelector, which offers square, 3:4, 4:3, 9:16 and 16:9. An LLMPromptManager builds the instruction from your text, for example 1950s, and APIProviderSelectorNode with ConfigGenerateImageOpenRouter selects the provider and model. GenerateImage then returns the grid, and SaveImage stores it.

The prompt field accepts a period like 1950s, or you can leave it blank. An extra prompt field can add more instructions. If there is no OpenAI key on the machine secrets, the notes say to write the full prompt yourself and remove the AI system prompt.

Tips

  • Crop your photo to the chosen aspect ratio, because the image is padded to size.
  • Use a front-facing photo with good lighting.
  • Try the free model variant for tests.
  • Name specific decades for more distinct results.

What you can use it for

  • Shareable then-and-now social posts
  • Retro decade looks of a person or pet
  • Family history style collages
  • Themed grid art for events

Frequently asked questions

What GPU does the Through the Ages workflow need?

It is listed as CPU, so no GPU is needed. Image generation is done by Google Gemini 2.5 Flash Image through OpenRouter.

Do I need an API key?

Yes. Enter your OpenRouter key in the external_api_key input. Models offered are google/gemini-2.5-flash-image-preview and its free variant.
