What is GPT-4.5?

GPT-4.5 is an upgraded intermediate version based on GPT-4 that OpenAI has made faster, more flexible, and more natural. Often called the 'precursor to GPT-5,' it offers noticeable improvements in processing speed and response quality compared to previous versions. It particularly shows smoother, more human-like responses in tasks like code interpretation, text generation, and translation. While there aren't major UI changes, users will frequently experience moments where they think, "Huh? Did it suddenly get smarter?"

How does it differ from GPT-4?

Comparison Item	GPT-4	GPT-4.5
Response Speed	Somewhat slow	Significantly faster
Context Retention	Moderate	Enhanced
Code Generation Accuracy	Excellent	Exceptional

Real-life use cases

GPT-4.5 plays a significant role in everyday scenarios. You can experience definite efficiency improvements in areas such as:

• Blog content creation speed doubled
• Translation quality approaching human-level translation
• Greatly improved contextual response capabilities in customer service chatbots

Technical improvements summary

GPT-4.5 goes beyond simple performance enhancements with substantial changes to its engineering structure. For example, computational optimizations have shortened overall response times, and improved token processing efficiency enables longer conversations without issues. API call response times have notably decreased, and error rates have fallen. I've summarized these in the table below.

Improvement Item	Before	After
Average response time	2.5 seconds	1.2 seconds
Processable token count	8,192	32,000+
API error rate	3.1%	1.2%

Who should use GPT-4.5?

I get this question a lot. While the honest answer is "anyone can use it," I particularly recommend it for:

• Marketers and writers who need to rapidly create content
• Developers requiring code testing or automation
• Planners and content strategists in need of creative ideas

GPT-5 and beyond?

The arrival of GPT-4.5 may signal that GPT-5 is just around the corner. The industry is already buzzing with rumors about what features GPT-5 might include. Autonomy, long-term memory, and real-time update capabilities seem almost certain, and evolution toward user-customized AI is also predicted. This era of change presents both opportunities and challenges for us. The future becomes increasingly intriguing.
