Model Summary
Revela-500M is a self-supervised bi-encoder dense-retriever trained with the Revela objective on raw Wikipedia text.
It uses the 500 M-parameter Qwen 2.5-0.5B backbone and was trained on 320 K Wikipedia batches (batch size = 16).
The in-batch attention mechanism enables fully self-supervised learning without manually-mined relevance labels.
See the paper for full details.

Usage
We can evaluate the trained models with customized mteb.
from mteb.model_meta import ModelMeta
from mteb.models.repllama_models import RepLLaMAWrapper, _loader
revela_llama_3b = ModelMeta(
loader=_loader(
RepLLaMAWrapper,

revela_llama_3b_model = revela_llama_3b.loader()
evaluation = mteb.MTEB(tasks=["SciFact", "NFCorpus"])
