OpenAI launched a research preview for GPT 4.5 and perhaps the biggest takeaway is that it can fake emotional intelligence pretty well--potentially better than a few humans we know.
The company outlined GPT-4.5 and noted that early testing shows that interactions with humans are more natural. OpenAI noted:
"Based on early testing, developers may find GPT‑4.5 particularly useful for applications that benefit from its higher emotional intelligence and creativity—such as writing help, communication, learning, coaching, and brainstorming. It also shows strong capabilities in agentic planning and execution, including multi-step coding workflows and complex task automation."

- OpenAI launches GPT Store, Team plan, eyes developer, enterprise traction
For collaboration, GPT-4.5 may be a win since it has more EQ.
Key points about GPT-4.5:
- GPT-4.5 scales unsupervised learning by scaling up compute and data and reduces hallucinations.
- GPT-4.5 scored better than GPT-4o on collaboration skills.
- The model doesn't think before it responds.
- ChatGPT Pro users can select GPT-4.5 today with Pro and Team users getting it next week followed by Enterprise and education users.
- GPT 4.5 is compute intensive and more expensive than GPT-4o. It is not viewed as a replacement.
Constellation Research’s take
Andy Thurai, analyst at Constellation Research, said:
“OpenAI claims GPT-4.5 will have fewer hallucinations and more accurate writing, programming, and insights.
This is not a reasoning model but an unsupervised learning model. GPT-4.5 doesn’t have a chain of thought like the reasoning models therefore can respond faster. Instead of combining the reasoning models and responding models, OpenAI chose to separate them as the execution costs, and model training costs can be very high for reasoning models such as OpenAI GPT-o1 and o3 mini.
With the models running out of world data, and the model differentiation from the LLM providers becoming less and less differentiated, all of them are looking for ways to stand out. OpenAI has taken the direction of making their chatbot more human. OpenAI claims its EQ is better than other models, meaning the model recognizes tone and intent and responds with empathy rather than just solutions—just like a real human would. With that approach interactions can feel more natural and human like.
In initial testing, GPT-4.5 seems to show strong capabilities in agentic planning and execution, including multi-step coding workflows and complex task automation. However, there is concern in initial tests that it can fake emotional intelligence just like humans would.
However, at the current time these models are very expensive. GPT-4.5 is also restricted only to Pro users for now because of GPU shortage per OpenAI’s claim.”
