Multi-hop retrieval-augmented QA agent fine-tuned from meta-llama/Llama-3.1-8B-Instruct with Bidirectional Evolutionary Search (BES) on the 3–4-hop subset of MuSiQue.

For the 3B variant see Xkev/Llama-3.2-3B-Instruct-multihop-BES.

Training

Base model: meta-llama/Llama-3.1-8B-Instruct
Dataset: 3–4-hop subset of MuSiQue (~5.5k examples)
