GPT-4.5: OpenAI takes another step forward in AI, but the real change is yet to come

Artificial intelligence is advancing fast, but the strategy behind each release matters just as much as the technology itself. OpenAI has just introduced GPT-4.5 , a model that expands its knowledge and efficiency, but that it does not yet represent the great leap expected . This model is, in essence, an intermediate step before the arrival of GPT-5 , where the company plans to merge the GPT model line with reasoners ( O1 and O3 ).

For those working in strategy, technology, and talent management, the key question is not just what GPT-4.5 can do, but what real impact it has on the business and whether it justifies its cost . Today, the most advanced version of OpenAI is only available to subscribers of ChatGPT Pro ($200/month) , although it is expected to come into the plans Bonus and Team in the coming weeks.

A wider model, but not smarter

GPT-4.5 does not introduce a technological breakthrough, but rather an evolution within the existing model. OpenAI has improved its responsiveness, computational efficiency, and alignment with user intent. The number of hallucinations has been reduced, language processing has been optimized and security has been strengthened to prevent misuse. However it is not the most powerful model in the company , as it still does not incorporate advanced reasoning capabilities such as those being developed in parallel.

In practical terms, this means that GPT-4.5 is still predictive AI rather than AI that actually "thinks" . She is faster, responds more naturally and handles emotional nuances in language better, but It does not revolutionize the way we interact with artificial intelligence .

Is GPT-4.5 worth paying for?

Competition intensifies: how does GPT-4.5 compare to Claude 3, Gemini 1.5, and DeepSeek?

The launch of GPT-4.5 it does not occur in a vacuum. OpenAI continues to lead conversational artificial intelligence, but it faces increasingly strong competition. Companies such as Anthropic, Google DeepMind, and DeepSeek They are betting on models with different approaches, from efficiency and accuracy to accessibility and open source.

Claude 3: the closest opponent

Anthropic presented the series in March 2024 Claude 3 , with three variants: Haiku (fast and light), Sonnet (balanced) and Opus (the most powerful). Since its launch, it has been considered the model with the best understanding of the context and capacity for critical analysis .

Claude 3 excels in:

• Comprehension of long texts : Handles references to previous information in a conversation better.
• Precision in logical reasoning : Their answers are usually more structured and clear on complex problems.
• Tone closer to the human : Their way of expressing themselves is less robotic and more natural.

However, despite its performance, Claude 3 still struggles in code generation and does not have real-time internet access, something that OpenAI does offer through its advanced tools.

Gemini 1.5: Google's bet on long-term memory

Google DeepMind launched Gemini 1.5 in February 2024 with a focus on Multimodality and extended memory . Its main difference with GPT-4.5 and Claude 3 is that can remember information within the same session with a much greater capacity for context, allowing for more fluid and coherent interactions.

Its strengths are:

• Expanded Context Capability : Can process and remember more information within a single conversation.
• Integration with the Google ecosystem : It is designed to work with tools such as Gmail, Docs, and Search.
• Advanced Multimodality : Handles images, audio, and video with smoother integration.

However its performance in text generation is not as refined as that of GPT-4.5 or Claude 3 . Despite its technical power, users have reported that its responses sometimes lack fluency and cohesion.

DeepSeek: the Chinese alternative in open source

DeepSeek has emerged as one of the most interesting bets in the world of AI. Your model DeepSeek-V2 , launched in January 2024, is an alternative that prioritizes Open Source and Programming Efficiency .

DeepSeek focuses on:

• Accessible and customizable models : Allows companies and developers to train and modify the model according to their needs.
• High precision in programming : It surpasses GPT-4 in code generation and correction.
• Focus on the Asian market : It is optimized for languages such as Chinese and English.

Despite its advantages, DeepSeek still doesn't reach the conversational sophistication of GPT-4.5 or Claude 3 , which limits it in more generalist applications.

Comparing the new features of ChatGPT with its previous versions

GPT-4.5 is an evolution within the GPT family, but how does it compare to its predecessors?

1. GPT-3.5 (November 2022)
   • First version that made ChatGPT viable.
   • AI more accessible, but with less accurate answers and a higher rate of hallucinations.
2. GPT-4 (March 2023)
   • Better reasoning and fewer errors.
   • Increased processing capacity and contextual understanding.
3. GPT-4o (May 2024)
   • Focus on speed and efficiency.
   • First major advance in multimodal interaction.
4. GPT-4.5 (February 2025)
   • Multiply the efficiency of GPT-4o by 10.
   • It further reduces hallucinations.
   • Improvement in emotional intelligence and conversational tone.

GPT-4.5 does not introduce a disruptive leap, but it refines the model in terms of efficiency, security and fluidity in the conversation .

How does OpenAI maintain its leadership?

Despite competition, OpenAI continues to dominate the conversational AI market for three key reasons:

1. Scalability strategy
   OpenAI has found the balance between incremental improvements and strategic releases. Although GPT-4.5 is not a revolution, it bolsters its leadership as it prepares for GPT-5 , which will make a structural difference.
2. Integration with advanced tools
   ChatGPT is not just a chatbot: its integration with Internet search, file upload, and code generation it keeps it ahead of its rivals.
3. Access and business ecosystem
   Although the Pro model costs $200 per month, OpenAI has been able to diversify its access with cheaper versions ( Plus and Team ), enabling more users to adopt AI without major financial barriers.

GPT-4.5 maintains OpenAI's lead, but the real battle will be fought with GPT-5 , where the company will have to demonstrate that it can offer not only a faster and more accurate model, but an AI with real reasoning capacity .

GPT-4.5, AI Agents and Operator: How the Future of Businesses Changes in 2025

The launch of GPT-4.5 is not just a technical improvement within the OpenAI ecosystem, but a reflection of a Deeper transformation in artificial intelligence applied to companies . We are not simply facing a more efficient AI or with fewer errors, but a paradigm shift in the use of AI Agents able to interact, execute tasks and collaborate with humans in a much more autonomous way.

In Proportione , we have repeatedly talked about how AI is not only a productivity tool, but a strategic player within the business world. And within this panorama, the arrival of Operator , OpenAI's agent system, is the Biggest change of 2025 .

GPT-4.5 is an incremental improvement, but Operator is the real leap forward in work automation .

GPT-4.5 represents an optimization in model efficiency, but the key question for any company is: How does it impact the operation and strategy?

1. Less friction in AI implementation

With fewer hallucinations and a greater capacity for contextual understanding, GPT-4.5 lowers the barrier to entry for companies that have not yet integrated AI into their processes . This means that:

• More tasks can be automated without the risk of significant errors.
• Chatbots and virtual assistants will be more reliable for customer service and internal support.
• AI will be able to take on more roles in content generation without the need for constant supervision.

The result is a smoother adoption of AI in work teams that previously viewed these models as unreliable.

2. More strategic and less transactional AI

Until now, AI in companies has been used mainly to Specific and repetitive tasks . GPT-4.5, with its improved emotional intelligence and conversational tone, allows interactions with AI to be more consultative and strategic .

Examples of this include:

• Deeper analysis in meetings and reports .
• Writing and improving documents with greater consistency and professional style .
• More accurate and distortion-free data-driven decision-making support .

GPT-4.5 is still not an advanced reasoning model, but it is closer to the ability to "think out loud" with users, which is key to knowledge work .

3. Move towards real automation with AI agents

GPT-4.5 is still a conversational model, but its arrival paves the way for the real revolution: AI agents .

OpenAI has already made it clear that the future of its technology lies in the agents , systems capable of not only answering questions, but also Execute tasks autonomously . And that's where Operator comes in.

Operator: the real change for businesses in 2025

If GPT-4.5 is an incremental improvement, Operator is the structural transformation of AI applied to business .

Operator is the system of OpenAI Autonomous Agents , which will allow AI not only to process information, but also to Act independently across different platforms and tools .

Imagine an AI that:

• Not only does it answer emails, but it manages and prioritizes them according to context and urgency.
• It not only suggests strategies, but coordinates tasks in a CRM or management software.
• Not only does it generate reports, but it automatically adapts them according to audiences and objectives.

Operator represents the move from conversational AI to executive AI , an automation layer that can Manage business processes without direct human intervention .

How will this impact the business structure?

The arrival of Operator means that companies will no longer only hire people, but AI agents who will work within the teams. This will have direct consequences on:

1. Roles and functions within organizations
   • Smaller teams, but more efficient thanks to automation.
   • Fewer administrative tasks and more focus on creativity and strategy.
2. Cost Structure and Business Models
   • Reduced operational costs by automating processes with AI.
   • Changes in hiring: Less demand for operational roles and more emphasis on AI management.
3. Competition and business differentiation
   • Companies that adopt Operator faster will have a significant competitive advantage.
   • The customization of AI agents will be a key differentiator between companies.

GPT-4.5 is an improvement, but Operator is OpenAI's strategic coup to stay on top .

While Claude 3, Gemini 1.5 and DeepSeek compete in response quality and language model efficiency , OpenAI has understood that the true power of AI is not only in responding better, but in Do things for users .

The new standard is not just to respond, but to execute.

Companies that understand this will not only be adopting AI, but completely transforming their operational structure. GPT-4.5 is another step on this path, but the real disruption will come with the integration of autonomous agents into the day-to-day business life.

The future of AI in business It's not just more intelligence, but more autonomy . And that's where OpenAI wants to lead the next era.
