ML-Embed: Inclusive and Efficient Embeddings for a Multilingual World

Ziyin Zhang, Zihan Liao, Hang Yu +2

The development of high-quality text embeddings is increasingly drifting toward an exclusionary future, defined by three critical barriers: prohibitive computational costs, a narro…

Beyond Retrieval: A Multitask Benchmark and Model for Code Search

Siqiao Xue, Zihan Liao, Jin Qin +4

Code search has usually been evaluated as first-stage retrieval, even though production systems rely on broader pipelines with reranking and developer-style queries. Existing bench…

E2LLM: Encoder Elongated Large Language Models for Long-Context Understanding and Reasoning

Zihan Liao, Jun Wang, Hang Yu +3

Processing long contexts is increasingly important for Large Language Models (LLMs) in tasks like multi-turn dialogues, code generation, and document summarization. This paper addr…

F2LLM-v2: Inclusive, Performant, and Efficient Embeddings for a Multilingual World

Ziyin Zhang, Zihan Liao, Hang Yu +2

We present F2LLM-v2, a new family of general-purpose, multilingual embedding models in 8 distinct sizes ranging from 80M to 14B. Trained on a newly curated composite of 60 million…

C2LLM Technical Report: A New Frontier in Code Retrieval via Adaptive Cross-Attention Pooling

Jin Qin, Zihan Liao, Ziyin Zhang +3

We present C2LLM - Contrastive Code Large Language Models, a family of code embedding models in both 0.5B and 7B sizes. Building upon Qwen-2.5-Coder backbones, C2LLM adopts a Pooli…

CodeFuse-CR-Bench: A Comprehensiveness-aware Benchmark for End-to-End Code Review Evaluation in Python Projects

Hanyang Guo, Xunjin Zheng, Zihan Liao +4

Automated code review (CR) is a key application for Large Language Models (LLMs), but progress is hampered by a "reality gap": existing benchmarks evaluate models on isolated sub-t…
