2025.09.30🌟 We are honored to open source Logics-Thinking-32B, excelling in complex logical and abstract reasoning.2025.09.15🌟 We are honored to launch Logics-Thinking-8B, a next-generation multimodal large model developed with great dedication by the Logics Team at Alibaba Group. Logics-Thinking is specifically engineered for advanced reasoning tasks, demonstrating outstanding performance in the domain of complex logical and abstract reasoning. This launch marks a key step in our mission to continuously push the frontiers of artificial intelligence, and we are excited for the future it will enable.
The Logics-Thinking training pipeline comprises three key steps: (1) Long CoT Data Synthesis, which involves Prompt Engineering and Selective Sampling; (2) Model Merging and (3) Advanced Training, which includes Supervised Fine-Tuning (SFT) and Reinforcement Learning (RL) methods.
