AI Explained - GPT 4.5 - not so much wow
GPT 4.5 was expected to be a significant advancement in AI, focusing on scaling up the base models with more parameters and data. However, it underperformed in various benchmarks, including science, mathematics, and coding, compared to smaller models like Claude 3.7. The model's emotional intelligence was also tested, revealing a tendency to overly sympathize with users, sometimes missing critical cues of inappropriate behavior. This was contrasted with Claude 3.7, which demonstrated a higher emotional intelligence by setting boundaries and recognizing fictional scenarios. Additionally, GPT 4.5's creative writing and humor capabilities were found lacking compared to Claude 3.7, which showed more nuanced and engaging outputs. Despite these shortcomings, GPT 4.5 is seen as a foundation for future reasoning models, with OpenAI planning to enhance it through reinforcement learning. The high cost of GPT 4.5, however, raises questions about its long-term viability, especially when compared to more cost-effective models like Claude 3.7.
Key Points:
- GPT 4.5 underperforms in benchmarks compared to Claude 3.7, especially in science and coding.
- The model's emotional intelligence is questionable, often failing to recognize inappropriate scenarios.
- Creative writing and humor are less effective in GPT 4.5 compared to Claude 3.7.
- Despite high costs, GPT 4.5 is intended as a foundation for future reasoning models.
- OpenAI plans to improve GPT 4.5 through reinforcement learning, but its current cost-effectiveness is debated.
