SD.Next Release 2026-02-04

[vladmandic]

Refresh release two weeks after prior release, yet we still somehow managed to pack in ~150 commits!
Highlights would be two new models: Z-Image-Base and Anima, captioning support for tagger models and a massive addition of new schedulers
Also here are updates to torch and additional GPU archs support for ROCm backends, plus a lot of internal improvements and fixes.

Details for 2026-02-04

• Models
  • Tongyi-MAI Z-Image Base
    yup, its finally here, the full base model of Z-Image
  • CircleStone Anima
    2B anime optimized model based on a modified Cosmos-Predict, using Qwen3-0.6B as a text encoder
• Features
  • caption tab support for Booru tagger models, thanks @CalamitousFelicitousness
  • add SmilingWolf WD14/WaifuDiffusion tagger models, thanks @CalamitousFelicitousness
  • support comments in wildcard files, using #
  • support aliases in metadata skip params, thanks @CalamitousFelicitousness
  • ui gallery improve cache cleanup and add manual option, thanks @awsr
  • selectable options to add system info to metadata, thanks @Athari
    see settings -> image metadata
• Schedulers
  • schedulers documentation has new home: https://vladmandic.github.io/sdnext-docs/Schedulers/
  • add 13(!) new scheduler families
    not a port, but more of inspired-by res4lyf library
    all schedulers should be compatible with both epsilon and flow prediction style!
    note: each family may have multiple actual schedulers, so the list total is 56(!) new schedulers
    • core family: RES
    • exponential: DEIS, ETD, Lawson, ABNorsett
    • integrators: Runge-Kutta, Linear-RK, Specialized-RK, Lobatto, Radau-IIA, Gauss-Legendre
    • flow: PEC, Riemannian, Euclidean, Hyperbolic, Lorentzian, Langevin-Dynamics
  • add 3 additional schedulers: CogXDDIM, DDIMParallel, DDPMParallel
    not originally intended to be a general purpose schedulers, but they work quite nicely and produce good results
  • image metadata: always log scheduler class used
• API
  • add /sdapi/v1/xyz-grid to enumerate xyz-grid axis options and their choices
    see /cli/api-xyzenum.py for example usage
  • add /sdapi/v1/sampler to get current sampler config
  • modify /sdapi/v1/samplers to enumerate available samplers possible options
    see /cli/api-samplers.py for example usage
• Internal
  • tagged release history: https://github.com/vladmandic/sdnext/tags
    each major for the past year is now tagged for easier reference
  • torch update
    note: may cause slow first startup/generate
    cuda: update to torch==2.10.0
    xpu: update to torch==2.10.0
    rocm: update to torch==2.10.0
    openvino: update to torch==2.10.0 and openvino==2025.4.1
  • rocm: expand available gfx archs, thanks @crashingalexsan
  • rocm: set MIOPEN_FIND_MODE=2 by default, thanks @crashingalexsan
  • relocate all json data files to data/ folder
    existing data files are auto-migrated on startup
  • refactor and improve connection monitor, thanks @awsr
  • further work on type consistency and type checking, thanks @awsr
  • log captured exceptions
  • improve temp folder handling and cleanup
  • remove torch errors/warings on fast server shutdown
  • add ui placeholders for future agent-scheduler work, thanks @ryanmeador
  • implement abort system on repeated errors, thanks @awsr
    currently used by lora and textual-inversion loaders
  • update package requirements
• Fixes
  • add video ui elem_ids, thanks @ryanmeador
  • use base steps as-is for non sd/sdxl models
  • ui css fixes for modernui
  • support lora inside prompt selector
  • framepack video save
  • metadata save for manual saves
