LOFI By CivitAI vs Prexi

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.

Prexi is a curated prompt library with 3,400+ image prompts tested by a three-person collective in Lisbon. You browse collections like Liminal Spaces or Tokyo Nights, copy prompts tuned for Flux 1.1 Pro, Midjourney v7, Nano Banana Pro, SD3.5, Seedance, and Veo, then remix variants without leaving the tab. Browsing and copying stay free, while Studio at $9 per month unlocks heavier generation limits.

Most prompt lists are scraped from forums and go stale when models update. Prexi re-tests batches by hand whenever Flux, Midjourney, or Nano Banana ships a new version, which matters if you need prompts that still render cleanly. The trade-off is a niche image prompt focus rather than general chat templates or video scripts.

Design directors, creative technologists, and music video directors use Prexi to pitch moodboards, paste model-specific prompts into fal.ai or Discord, and share collection URLs instead of Pinterest boards. Free accounts get one preview generation per day; Studio raises that to 100 daily preview generations.
