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

1. Low-Precision Training for Efficiency

The model has been optimized to reduce computational costs while enhancing performance, making AI more accessible and efficient.

2. Multi-Data Center Pretraining

For the first time, GPT-4.5 was trained simultaneously across multiple data centers, a groundbreaking shift in AI development methodology.

Pricing & Availability

Expanded Context Window

• GPT-4.5 now supports 128K tokens, enabling longer and more coherent responses for complex tasks.

Pricing Model

• $75 per million input tokens.

• $37.50 per million cached input tokens.
