Summary

Darwin-35B-A3B-Opus is a cutting-edge language model created by VIDRAFT through an innovative evolutionary merge process that combines the strengths of two parent models: Qwen3.5-35B-A3B, known for its multimodal capabilities and extensive language support, and Claude 4.6 Opus, recognized for its advanced reasoning skills. The model achieves superior reasoning performance with a GPQA score of 90.0%, exceeding both parents, while maintaining the Father's multilingual expertise. The evolutionary merge is guided by Model MRI, a technique that analyzes and optimizes specific neural layers, resulting in a precise integration of capabilities from each parent model. Darwin V5's unique approach to model merging allows it to retain critical functions such as multimodal processing and multilingual support, while overcoming the limitations of traditional methods by employing layer-specific adjustments and replacing "dead" experts from the Mother with active ones from the Father. The model is fully open-source under the Apache 2.0 license, making it accessible for both commercial and research purposes.
