Model Implementations¤

This catalog tracks the live runtime surface shipped under artifex.generative_models.models. It does not treat deleted stubs or roadmap-only standalone pages as supported model API.

Family Packages¤

Family	Owner package	Representative exports
VAE	`artifex.generative_models.models.vae`	`VAE`, `BetaVAE`, `ConditionalVAE`, `VQVAE`
GAN	`artifex.generative_models.models.gan`	`GAN`, `DCGAN`, `WGAN`, `LSGAN`, `ConditionalGAN`, `CycleGAN`
Diffusion	`artifex.generative_models.models.diffusion`	`DiffusionModel`, `DDPMModel`, `ScoreDiffusionModel`, `LDMModel`, `DiTModel`, guidance helpers
Flow	`artifex.generative_models.models.flow`	`NormalizingFlow`, `RealNVP`, `Glow`, `MAF`, `IAF`, `NeuralSplineFlow`
Energy	`artifex.generative_models.models.energy`	`EBM`, `DeepEBM`, `EnergyBasedModel`, Langevin helpers
Autoregressive	`artifex.generative_models.models.autoregressive`	`PixelCNN`, `WaveNet`, `TransformerAutoregressiveModel`
Geometric	`artifex.generative_models.models.geometric`	`GraphModel`, `MeshModel`, `PointCloudModel`, `VoxelModel`, protein geometric models

Diffusion Surface¤

Use the top-level diffusion package for the supported exported family surface:

from artifex.generative_models.models.diffusion import (
    DDPMModel,
    DiTModel,
    DiffusionModel,
    LDMModel,
    ScoreDiffusionModel,
)

Stable Diffusion currently remains a module-local owner rather than a top-level package export:

from artifex.generative_models.models.diffusion.stable_diffusion import StableDiffusionModel

StableDiffusionModel is not re-exported from artifex.generative_models.models.diffusion.

Backbone And Standalone-Page Boundaries¤

UNet is currently owned by the backbone package, not by a standalone models.common.unet model module.

from artifex.generative_models.core.configuration import UNetBackboneConfig
import artifex.generative_models.models.backbones.unet as diffusion_unet

Use UNetBackboneConfig and the live backbone owner artifex.generative_models.models.backbones.unet for retained UNet building blocks.

Planned Standalone Pages¤

The following pages remain relevant to the roadmap, but they are not part of the supported model-reference surface today:

standalone UNet page
shared conditioning module page
standalone StyleGAN page

See planned-modules.md for the roadmap-only entries behind those pages.
