모델 상세 정보
각 모델의 상세한 파라미터, 예제, 활용 팁은 개별 문서에서 확인하세요.
Background Remover
851 Labs
The most-used background remover on Replicate (27M+ runs). Removes backgrounds with soft alpha or hard segmentation, supports reverse mode (remove foreground), custom background types, and transparent PNG output — all at a very low price.
BiRefNet
BiRefNet
State-of-the-art open-source background removal. BiRefNet's high-fidelity dichotomous image segmentation delivers excellent edge quality on hair, fur, and fine details.
Clarity Upscaler
Clarity
The famous creative upscaler (30M+ runs). Instead of just enlarging, it re-imagines detail while upscaling — with controllable creativity, resemblance, prompt guidance, and tiled diffusion for high scale factors.
CodeFormer
CodeFormer
Robust face restoration for old photos and AI-generated faces (54M+ runs). Its signature fidelity dial balances restoration quality against staying true to the original face, with Real-ESRGAN background enhancement built in.
GFPGAN
Tencent ARC
Tencent ARC's face restoration model — 115M+ runs, the most-run model in the restoration collection. Restores old/blurry photos and fixes faces in AI-generated images.
Topaz Image Upscale
Topaz Labs
Professional-grade upscaling from Topaz Labs, the industry standard for photo enhancement. Five specialized enhance models, up to 6x upscale, subject detection, and optional face enhancement.
Bria Increase Resolution
Bria
Bria's commercially-safe image upscaler (130K+ runs). Increase resolution 2x or 4x with a model trained exclusively on licensed data, preserving alpha transparency — built for enterprise pipelines that require full legal liability coverage.
Pruna P-Image Upscale
Pruna AI
PrunaAI's high-end image upscaler (575K+ runs) reaching up to 128-megapixel output. Target-megapixel or factor-based control, optional detail/realism enhancement passes, and megapixel-tiered pricing that starts at just 15 credits.
Real-ESRGAN
Real-ESRGAN
The classic image upscaler (94M+ runs). Real-ESRGAN super-resolution up to 10x with optional GFPGAN face enhancement — the go-to default for cleanly enlarging photos and AI images.
Recraft Crisp Upscale
Recraft
Fast, affordable upscaler from Recraft designed for sharp, crisp results — a single image input with no tuning needed. Great default for UI assets, illustrations, and product images.
Remove Background
Bria AI
AI-powered background removal tool for images. Clean, accurate cutouts for any subject with professional-quality edge detection.
Remove BG
lucataco
One of the most-run background removers on Replicate (17M+ runs). A single-parameter API that strips the background and returns a transparent PNG — at just 1 credit per image, the cheapest cutout on the platform.
Google Upscaler
Google's image upscaler (770K+ runs). Upscale images 2x or 4x using generative AI while preserving natural detail, with adjustable output compression — a simple, reliable enhancer at a flat price.
