Flux 2 / Klein Models

Flux 2 / Klein AI models

FLUX.2 is Black Forest Labs' second generation: a larger text-to-image and editing model with native multi-reference input, far better text rendering, 4 megapixel output and a unified architecture that generates and edits in one pass. The dev weights are open, so the community has already trained more than a thousand FLUX.2 LoRAs. This page tracks them all: realism and skin detail, product and fashion looks, anime and illustration styles, plus the base checkpoints, ranked by heat so the LoRAs people are actually downloading this week rise to the top.

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.

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.

Flux vs SDXL vs SD 1.5 vs Qwen vs Z-Image: which model family to use in 2026
A practical comparison of the open image model families: prompt following, realism, anime and illustration, text rendering, speed, VRAM, LoRA ecosystem and licence, with a recommendation for each kind of work and hardware.

Prompting
FLUX.2 prompting guide: natural-language prompts, multi-reference, editing and LoRAs
Prompting FLUX.2 dev for the results it is known for: paragraph prompts with subject, scene, light and lens, exact text in quotes, up to several reference images for products, people and styles, instruction-style edits, the guidance and step settings that matter, and how FLUX.2 LoRAs differ from Flux dev LoRAs.

No install required - run AI models on the cloud
No GPU, no downloads, no Python. These services run the same open source models on their own servers, so you can start generating from a browser, Discord or Telegram in a minute.
