We expect GPT-5 to be more advanced than its predecessors. So, how could this be possible? Will it come from improvements in data quality, model architecture, fine-tuning, or new architectural approaches? In your opinion, which areas could see a major breakthrough?

One of the key areas where GPT-5 could make a leap is **data quality and volume**. Instead of relying on the "scraped-internet-data" approach of previous models, it could leverage calibrated scientific publications, high-quality code repositories (e.g., GitHub's most commented projects), and human-level edited texts. For instance, using a **corrected version of Project Gutenberg** or **verified articles from arXiv** instead of Common Crawl would provide a cleaner foundation. Additionally, **time-stamped data streams** (real-time news + research publications) could help the model stay up-to-date.
In terms of model architecture, we need to move beyond **complex attention mechanisms**. To overcome the limitations of Transformer-based models, increasing the number of **mixture-of-experts (MoE) layers** and implementing **hierarchical attention** to manage long-term dependencies could be explored. For example, new architectures like **RetNet** (Retrieval-Augmented Transformer) can dynamically retrieve past context and enrich it with new data. **High-level abstraction layers**, similar to skip-thought vectors, could also deepen meaning extraction.
When it comes to fine-tuning, a **real-time learning system based on human feedback** should be established. Instead of Reinforcement Learning from Human Feedback (RLHF), **online learning** models could be integrated, allowing continuous calibration by instantly feeding user interactions back into the model. Furthermore, **multimodal fine-tuning** (text + code + structured data) could enable the model to specialize across different domains.
Finally, **integration with research databases** plays a crucial role. For example, incorporating data from medical journals like **PubMed Central** could improve accuracy in the medical field, or pulling **function documentation from GitHub** could enhance code generation. For a new model to truly be considered "intelligent," it would need to combine these data sources into **specialized modules**.
