🔍 xVerify-8B-I

xVerify is an evaluation tool fine-tuned from a pre-trained large language model, designed specifically for objective questions with a single correct answer. It accurately extracts the final answer from lengthy reasoning processes and efficiently identifies equivalence across different forms of expressions.

✨ Key Features

📊 Broad Applicability

Suitable for various objective question evaluation scenarios including math problems, multiple-choice questions, classification tasks, and short-answer questions.

⛓️ Handles Long Reasoning Chains

Effectively processes answers with extensive reasoning steps to extract the final answer, regardless of complexity.

🌐 Multilingual Support

Primarily handles Chinese and English responses while remaining compatible with other languages.

🔄 Powerful Equivalence Judgment

✓ Recognizes basic transformations like letter case changes and Greek letter conversions
✓ Identifies equivalent mathematical expressions across formats (LaTeX, fractions, scientific notation)
✓ Determines semantic equivalence in natural language answers
✓ Matches multiple-choice responses by content rather than just option identifiers
