LOFI By CivitAI vs ThisPersonDoesNotExist

LOFI is a Stable Diffusion 1.x checkpoint published on Civitai for photorealistic portraits and subject-focused images. The v5-final release ships as a 2.39 GB fp16 SafeTensor file and targets users who want a tuned 1.5 base model rather than building their own fine-tunes from scratch.

Compared with stock SD 1.5 checkpoints, LOFI emphasizes prompt fidelity at low CFG values and portrait-heavy compositions. Version 5 recommends CFG between 2 and 5 with DPM++ samplers, works with LCM or HyperSD distillation helpers, and warns that scenes without a clear subject can be harder to generate without ControlNet depth guidance.

Digital artists, hobbyists, and SDXL users who keep a 1.5 refiner pipeline download LOFI for portrait work, ControlNet-guided layouts, and inpainting variants across the version history on Civitai.

ThisPersonDoesNotExist.com is a website created by Philip Wang, a software engineer at Uber, that showcases the capabilities of AI-generated fake portraits. The site utilizes an algorithm trained on a large dataset of real images and employs a neural network called a generative adversarial network (GAN) to produce convincing fake facial images. It serves as a demonstration of the advancements in AI and the potential for creating realistic visuals.
