mj1-checkpoint MMRB2 Evaluation Results

This dataset contains the evaluation results of mj1-checkpoint on the MMRB2 (Multimodal RewardBench 2) benchmark.

Dataset Description

The MMRB2 benchmark evaluates reward models on multimodal understanding and interleaved generation across 4 task types:

Total pairs evaluated: 4000

Files

• all_results.jsonl - All evaluation results in JSONL format (for HuggingFace datasets)
• all_results.json - All evaluation results in JSON format
• task_*.json - Individual task results (original format)

Schema

Each record contains:

• pair_id: Unique identifier for the pair
• task_type: Task type (image/edit/interleaved/reasoning)
• model_name: Model used for evaluation
• forward_judgement: Judgement when responses shown as A, B
• reverse_judgement: Judgement when responses shown as B, A
• forward_metadata: Full model output and reasoning (JSON string)
• reverse_metadata: Full model output and reasoning (JSON string)
• forward_reasoning: Extracted reasoning (if available)
• reverse_reasoning: Extracted reasoning (if available)
• forward_confidence: Model confidence score (if available)
• reverse_confidence: Model confidence score (if available)

Usage

from datasets import load_dataset

# Load from local files
dataset = load_dataset('json', data_files='all_results.jsonl')

# Or load specific task
dataset = load_dataset('json', data_files='task_image_*.json')
