CrafterDojo v1 weights

Pretrained models from CrafterDojo: An Integrated Research Suite for Building Open-Ended Embodied Agents in Crafter (paper, code, project).

File	Model	Notes
vpt/tiny.safetensors	CrafterVPT-tiny	behavior cloning, last checkpoint
vpt/base.safetensors	CrafterVPT-base	behavior cloning, last checkpoint
vpt/large.safetensors	CrafterVPT-large	behavior cloning, last checkpoint
crafterclip/crafterclip.safetensors	CrafterCLIP	video–caption encoder (MineCLIP architecture, ViT-B/16 backbone)
steve1/steve1.safetensors	CrafterSteve-1	instruction-following policy (LoRA on CrafterVPT-base)
steve1/steve1_prior.safetensors	CrafterSteve-1 prior	text → visual-goal CVAE prior
vpt/*.yaml	architecture configs	same files as models/vpt/*.yaml in the code repository

All models are trained on the sv_gh_pp-10B_20ep CrafterPlay mixture (Survival + Gatherer experts) in Craftax-Classic. Each .safetensors file records its training run in the header metadata.

Usage

git clone https://github.com/frechele/CrafterDojo && cd CrafterDojo
bash scripts/download_weights.sh      # downloads this repository (revision v1.0) into models/

Load with the repository's helpers (crafterdojo.common.checkpoint.load_state_dict), which also restore the shared CLIP tensors in CrafterCLIP (stored once, listed in the aliases metadata entry).
