GPT-4.5 vs. Previous Models: A Performance Breakdown
1. More Context-Aware and Emotionally Intelligent
Compared to GPT-4 (01), GPT-4.5 has a significantly improved ability to recognize tone and intent. For example:
If asked to draft a response to a canceled plan, GPT-4.5 suggests a diplomatic and understanding message, while GPT-4.0 might simply follow instructions without considering social context.
2. Improved Knowledge-Based Responses
When explaining complex topics like AI alignment, GPT-4.5 doesn’t just provide facts—it structures answers logically, making them more accessible and engaging.
3. Evolution of Answer Quality Over AI Generations
A comparison of responses to the question "Why is the ocean salty?" across different GPT models highlights its improvement:
GPT-1: Nonsensical and inaccurate.
GPT-2: Slightly relevant but still incorrect.
GPT-3.5: Correct but poorly structured.
GPT-4: Accurate but overly detailed.
GPT-4.5: Concise, well-structured, and engaging.
Benchmarks and Real-World Performance
1. General Knowledge and QA Benchmarks
GPT-4.5 outperforms all previous OpenAI models in factual accuracy and context retention:
GPT QA Benchmark Score: Improved from 53% (GPT-4) to 71% (GPT-4.5).
Significantly reduced hallucination rates, ensuring more reliable information.
2. Coding and Freelance Market Performance
GPT-4.5 was tested in the Swancer Diamond Benchmark, which evaluates freelance coding efficiency:
GPT-4.5 earnings: $186,000.
GPT-4 earnings: $138,000.
03 mini earnings: $90,000.
This suggests that GPT-4.5 is not only smarter but also more efficient for freelancers and developers seeking AI-assisted work.
3. Future-Ready AI Model
GPT-4.5 serves as a robust foundation for future AI models, improving integration with reasoning-based agents and tool-using AI systems.
Technical Innovations Behind GPT-4.5
