Flux AI models
Flux is the family of text-to-image models released by Black Forest Labs in 2024: FLUX.1 dev and schnell, the Kontext editing models and the Fill, Depth and Canny tools. It is a 12 billion parameter flow-matching transformer that follows long natural-language prompts closely, renders readable text and keeps hands and anatomy intact, which made it the first real step past SDXL for realism. The catalog lists the Flux checkpoints and every Flux LoRA, from photographic styles and character LoRAs to lighting, film stock and illustration packs, each with example images, trigger words and a heat score.

ComfyUI errors and how to fix them: red nodes, missing models, CUDA out of memory
The ComfyUI error messages people hit first, what each one means and the fix that works: missing custom nodes (red boxes), "Prompt outputs failed validation", CUDA out of memory, wrong model type in a loader, mat1 and mat2 shape errors, header deserialization, torch and xformers mismatches.

What is a LoRA and how to use one in ComfyUI, Forge, Automatic1111 and on the cloud
LoRAs explained for people who want results, not maths: what a LoRA file changes, why it must match the base model's family, trigger words, weights, stacking several LoRAs, the folder and syntax for each UI, and how to try a LoRA on the cloud before downloading anything.

FLUX.1 Krea Dev: photographic realism without the AI look
FLUX.1 Krea Dev is the opinionated, photo-first Flux. This guide explains its aesthetic, the guidance and step values that suit it, how to prompt for natural light and texture, and creative ideas for documentary-style images.

CUDA out of memory: how much VRAM each AI model needs and how to fit it
A VRAM table for SD 1.5, SDXL, Flux, FLUX.2, Qwen-Image, Z-Image, Wan 2.2 and HunyuanVideo, and the techniques that make a model fit: fp8 and GGUF quantisation, CPU offload, tiled VAE, resolution and frame limits, and when to stop fighting and run it hosted.
