🎯Overview

We present MM-Eureka-Qwen-7B and MM-Eureka-Qwen-32B, both are powerful multimodal reasoning models that successfully extend large-scale rule-based reinforcement learning (RL) to multimodal reasoning. Compared to the previous version of MM-EUREKA based on InternVL, we have made improvements in model architecture, algorithms, and data. For instance, MM-Eureka-Qwen-7B achieves 66.1 on MMK12 evaluation sets, only 0.2 points below InternVL-2.5-78B. On MathVista(testmini), it reaches 73.0, even surpassing InternVLVL-2.5-78B. MM-Eureka-Qwen-32B demonstrates stronger performance, scoring 72.3 on MMK12 evaluation sets, which exceeds both Qwen2.5-VL-72B's 70.3 and closed-source models like Gemini2-Flash, ranking second only to o1's 73.9. On commonly used multimodal mathematical reasoning benchmarks, MM-Eureka-Qwen-32B achieves 73.4 on WeMath, outperforming all open-source models and most closed-source models including Claude3.7 Sonnet. On MathVista, it reaches 74.8, surpassing all open-source and closed-source models. Both variants demonstrate significant improvements in multidisciplinary K12 and mathematical reasoning performance, outperforming most open-source models of similar sizes.

Core Improvements:

1. We further iterate the codebase to support algorithms including Online Filter, ADORA, and DAPO.
2. We open-source self-collected MMK12, which has 15k diverse and high-quality samples and 2k MCQs for Math, Physics, Chemistry, Biology for evaluation.
3. We train the MM-Eureka-Qwen-7B and MM-Eureka-Qwen-32B, which are the almost top performer in multimodal reasoning within similar size open-source models. Especially for Multidisciplinary K12 tasks.

🔥We open-source our complete pipeline to foster further research in this area. We release all our codes, models, data, etc. at MM-EUREKA-Qwen.

🚀 Features

This repository is built upon OpenRLHF, introducing several key enhancements:

• Multimodal RFT Support: Extends OpenRLHF to incorporate vision-language models (VLMs), currently supporting InternVL, enabling multimodal reasoning capabilities.
  • Currently support RLOO, REINFORCE++, GRPO training using Ray.
  • vLLM integration and distributed training.
  • Support hybrid engine (--colocate_all_models, --vllm_enable_sleep).
• Better Rule-based Reward support: Better training visualization for Rule-based Rewards (i.g. Format Reward, Accuracy Reward, Repetition Penalty)
• Enhanced Online Filtering: Filtering out experiences based on Accuracy Reward during training as in PRIME
  • Use --enable_accuracy_filter, --freezing_filter_steps, --accuracy_lower_bound, --accuracy_upper_bound to control the behavior of online accuracy filter.
• ADORA: Enable Adaptive Online Rollout Adjustment by using --use_adora and --adora_lamda as in ADORA.
• DAPO: You can use --use_dapo to enable DAPO loss during training as in DAPO.
• CPGD: You can use --use_cpg_loss and --use_policy_drift to enable CPGD loss during training as in CPGD. Additionally:
  • --policy_drift_coef controls the weight of the policy drift regularizer, and --policy_drift_clip_eps controls the clipping range in policy drift.
  • --use_clip_filter_like_weight enables the clip-filter-like weight proposed in CPGD, and --clip_filter_like_weight_clip_eps controls the clipping range in the clip-filter-like weight.
  • Example script is provided in MM-EUREKA/examples/scripts/train_cpgd_qwen_7b_single_node.sh or MM-EUREKA/examples/scripts/train_cpgd_qwen_7b_multi_node.sh.

🤖 Models

Based on the key factors identified by https://github.com/ModalMinds/MM-EUREKA for achieving stable training, we enhanced the model, dataset, and algorithmic modules. Specifically, we maintained the strategy of omitting the KL divergence term and applying data filtering, while implementing the following critical modifications:

• The base model was upgraded from InternVL2.5-8B-Instruct to the more powerful Qwen2.5-VL-7B-Instruct.
• The Vision Transformer (ViT) module was frozen during training.
• The underlying RL algorithm was replaced with GRPO, instead of the previously used RLOO.
• The data filtering strategy was transitioned from an offline approach to an online approach.
• Additional data from the K12 dataset was collected, expanding the total dataset size to 15,000 samples.
