According to reports, the model was pre-trained on over 20 trillion tokens —a staggering amount of data that dwarfs many of its competitors. This massive dataset provides the model with a broad foundation of knowledge, enabling it to understand context deeply and generalize effectively across different scenarios.
But pre-training is only part of the story. After the initial phase, Qwen2.5-Max underwent meticulous supervised fine-tuning (SFT) and reinforcement learning from human feedback (RLHF). These steps ensure that the model doesn’t just spit out answers—it generates responses that align with human expectations and preferences. This level of refinement is crucial for creating AI systems that feel intuitive and reliable.
