Model weights for EVOKE (paper), a 3-step, CFG-free interactive world model that generates 384 × 640 @ 24 fps video and stays coherent over 30 s rollouts. Code, docs and demos live in the GitHub repository — this repository holds weights only.
- ⚡ 3 steps, zero CFG — 1.5 s of video every 2.11 s on one H200, one forward per step.
- 🌍 Endless, not windowed — scene geometry lives in an external camera-indexed world state bank, so the denoiser context stays bounded however long the session runs.
- 🎛️ Re-promptable mid-flight — change the prompt while the rollout is running, no cut, no restart.

Usage
git clone https://github.com/AlayaLab/Evoke && cd Evoke
pip install -r requirements.txt
hf download AlayaLab/Evoke --local-dir models
hf download pkqbajng/ViGeo --local-dir models/ViGeo1.1 # REQUIRED depth backend
MODE=t2v NUM_CHUNKS=20 bash scripts/inference/infer_post_distill.sh
ViGeo is a separate download and is required — every shipped recipe uses it as the depth backend
behind the world state bank. Depth-Anything-3 is optional. Both ship under CC-BY-NC-4.0, which is more
restrictive than this repository's Apache-2.0; check their licences before any commercial use.
Inference modes, the mode × model matrix, hour-scale rollouts and training are documented in the GitHub repository.
Notes
The distilled models were trained on v2v conditioning alone, so MODE=i2v|t2v on them is zero-shot;
only stage1_camera_control has all three modes in distribution.
The vae / text encoder / tokenizer / scheduler in evoke-base/ come from the released
Helios base, which traces them to Wan. The EVOKE teacher is
built on LingBot-World.
