GPT-4.5 offers several improvements over GPT-4, particularly in areas related to tacit knowledge understanding, which involves the ability to grasp and apply knowledge that is not explicitly stated but is essential for nuanced and effective interaction. Here are some key enhancements:
1. Enhanced Computational Efficiency: GPT-4.5 boasts over a tenfold improvement in computational efficiency compared to GPT-4. This efficiency allows the model to process information more quickly and effectively, which can enhance its ability to understand and apply tacit knowledge in real-world scenarios[3].
2. Reduced Hallucination Rates: GPT-4.5 shows a significant reduction in hallucination rates, achieving 78% accuracy on the PersonQA evaluation compared to 28% for GPT-4o. Hallucinations refer to instances where a model provides information that is not based on actual data. Lower hallucination rates indicate better understanding and application of tacit knowledge by providing more accurate and reliable information[3].
3. More Natural Interaction: Internal testers describe GPT-4.5 as "warm, intuitive, and natural," highlighting its improved aesthetic intuition and creativity. This suggests that GPT-4.5 can better understand and respond to subtle cues in communication, which is crucial for grasping tacit knowledge[3].
4. Advanced Persuasion Skills: GPT-4.5 performs at cutting-edge levels in persuasion assessments, indicating its ability to understand and apply persuasive strategies effectively. This skill is closely related to tacit knowledge, as it involves understanding how to influence others through nuanced communication[3].
5. Improved Alignment Techniques: New scalable alignment methods have been developed for GPT-4.5, allowing for the training of larger models with data sourced from smaller models. This improvement enhances the model's ability to align with user intent and understand nuanced instructions, which is essential for applying tacit knowledge in complex tasks[5].
6. Broader Knowledge Base and Multilingual Capabilities: GPT-4.5 has a broader knowledge base and stronger multilingual capabilities, which can aid in understanding and applying tacit knowledge across different cultural and linguistic contexts. While GPT-4 already handles multiple languages effectively, GPT-4.5 further enhances these capabilities[1][3].
Overall, GPT-4.5's improvements in computational efficiency, reduced hallucination rates, and enhanced interaction capabilities contribute to its ability to better understand and apply tacit knowledge compared to GPT-4. However, it is noted that GPT-4.5 does not introduce entirely new capabilities but rather represents an evolutionary enhancement of existing ones[3].
