long_rolling_plain_from_ode_init
OmniMem long rolling video generation with a fixed prompt, using an ODE-derived self-forcing initialization.
This release contains the EMA generator checkpoint at training step 1500. The plain rolling-training run initialized from step-800 self-forcing EMA weights in the ODE lineage.

safetensorsweight shards and their index SHA256SUMSfor payload integrity checking
The weights retain their original FP32 storage. The model configuration uses NSA top-12 block selection.
Usage
Use compatible OmniMem code with CausalWanNSAModel and CausalWanT2VPipeline.
The Wan2.1 VAE, UMT5 text encoder, and tokenizer are separate required components.
from omnimem.models.transformers.causal_wan_nsa_model import CausalWanNSAModel
model = CausalWanNSAModel.from_pretrained(
"omnimem/long_rolling_plain_from_ode_init"
)
The original checkpoint configuration is preserved unchanged. Its saved class name
records the training wrapper, and _name_or_path records the initialization source.
The released weights are the step-1500 EMA weights.
