Browse and download AI upscaling models from OpenModelDB

OpenModelDB

Browse and download AI upscaling models from OpenModelDB.

Install

pip install openmodeldb

CLI

openmodeldb

Select scale → pick a model → download.

Python API

from openmodeldb import OpenModelDB

db = OpenModelDB()
# <OpenModelDB: 658 models>

# List models (formatted table)
db.list(scale=4)
db.list(scale=1, architecture="compact")

# Find models (returns list[Model])
models = db.find(scale=4)
compacts = db.find(scale=1, architecture="compact")

# Search by name, author, tags or description
results = db.search("denoise")

# Download by name or Model object
db.download("4xNomos8k_atd_jpg")
db.download(models[0])
db.download(models[0], dest="./my_models/")

# Download a specific format (pth, safetensors, onnx)
db.download("4xNomos8k_atd_jpg", format="safetensors")

# Auto-conversion between pth and safetensors
# If the requested format is unavailable, downloads the other and converts
db.download("2x-HFA2kAVCCompact", format="safetensors")  # only pth available → auto-convert
db.download("1x-SuperScale", format="pth")                # only safetensors → auto-convert

# Download as ONNX with auto-conversion
# If no ONNX file is available, downloads .pth/.safetensors and converts automatically
db.download("4xNomos8k_atd_jpg", format="onnx")
db.download("2x-DigitalFlim-SuperUltraCompact", format="onnx", half=True)  # FP16 export

# Download all available formats
db.download_all("4xNomos8k_atd_jpg")
db.download_all("4xNomos8k_atd_jpg", format="pth")  # only .pth files

# Verify model integrity (compare weights against database reference)
db.test_integrity("downloads/4xNomos8k_atd_jpg.pth")
# ✓ PASS  similarity=100.000000  matched=53/53  max_diff=0.00e+00  mean_diff=0.00e+00

# Silent mode (no output, for use as a library)
path = db.download("4xNomos8k_atd_jpg", quiet=True)

# Get download URL (for custom download logic)
url = db.get_url("4xNomos8k_atd_jpg")
url = db.get_url("4xNomos8k_atd_jpg", format="safetensors")

# Dict-style access
model = db["4xNomos8k_atd_jpg"]
print(model.name, model.author, model.scale, model.architecture)

# Check if a model exists
"4xNomos8k" in db  # True

# Browse architectures and tags
db.architectures()  # ['atd', 'compact', 'cugan', 'dat', ...]
db.tags()           # ['anime', 'denoise', 'photo', ...]

# Iterate
for model in db:
    print(model)

# Launch interactive CLI
db.interactive()

Dependencies

• InquirerPy — interactive prompts
• rich — progress bars and tables
• pycryptodome — Mega.nz decryption

Conversion (optional)

pip install openmodeldb[convert]

Enables automatic conversion between formats: pth ↔ safetensors ↔ ONNX.

• PyTorch — model loading and ONNX export
• safetensors — safe tensor serialization
• onnx — ONNX model format
• onnxruntime — graph optimization
• spandrel — universal model loader
