AI Image Generation for Blog Covers: FLUX vs Pexels API for Travel Content

For about-kazakhstan.com I needed cover images for 83 articles. Some topics work with AI generation, others absolutely dont. Here is what I learned. When to Use AI (FLUX/Runware) Landscapes, abstract scenes, atmospheric shots Historical illustrations (Kazakh Khanate, Silk Road) Nature scenes (mountains, steppes, canyons) I use Runware API with FLUX.1 Dev (Nano Banana 2 model) at 1344x768px. # generate-covers.py response = runware . generate ( model = " google:4@3 " , # Nano Banana 2 prompt = " Vast Kazakh steppe at golden hour, mountains in distance " , width = 1344 , height = 768 ) When to Use Real Photos (Pexels API) Cities, buildings, streets Food and cuisine People and clothing Anything where accuracy matters AI generates plausible but wrong food. Kazakh beshbarmak from AI looks nothing like real beshbarmak. For Kazakh food articles , always use real photos. // Pexels API for real photos const photos = await pexels . photos . search ({ query : " kazakh traditional food " , per_page
