Cross Encoder Reranker
Reranks retrieved candidates with a cross-encoder scoring pass.
Model Details
- Artifact type: full fine-tuned model
- Base model:
sentence-transformers/all-MiniLM-L6-v2 - Backbone type:
encoder - Model ID:
L2 - Tier:
repository_library_search_stack - Role in stack: search-stack component for retrieval, reranking, or routing
This model is part of the Repository Library stack, a research system for indexing, retrieving, aligning, and reasoning over scientific papers, structured paper content, repositories, and cross-domain links between them.

Intended Use
- Primary use: Reranks retrieved candidates with a cross-encoder scoring pass.
- Downstream use: retrieval, ranking, planning, paper understanding, or cross-domain reasoning inside the broader Repository Library system, depending on the model family.
- Out of scope: production safety claims, benchmark claims beyond the tracked experiment config, or deployment without task-specific validation.

Usage
from transformers import AutoModelForSequenceClassification, AutoTokenizer
repo_id = "PeytonT/cross-encoder-reranker"
tokenizer = AutoTokenizer.from_pretrained(repo_id)
model = AutoModelForSequenceClassification.from_pretrained(repo_id)
Limitations
- These cards are generated from tracked experiment metadata and packaged artifacts, not from a separate benchmark report or external audit.
- Several training sources are pipeline outputs from the Repository Library codebase rather than standalone public datasets.
- These models are components of a larger research system and should be validated in their target workflow before deployment.
