What is the news?

Artificial Intelligence (AI) company OpenAI has launched its new and more powerful AI model GPT-5.4. This model has been specially designed keeping in mind professional and enterprise work. Improvements like better accuracy, faster performance and lower error rate have been made in it. The new model is said to be more capable of handling large documents and complex data, which can help developers and companies make many types of tasks easier.

Larger context window and better reasoning

The biggest feature of GPT-5.4 is its large context window. This model supports up to one million tokens in a single API request, allowing large documents and long data sets to be processed simultaneously. Apart from this, its reasoning ability has also been improved, which can provide more accurate answers in solving complex problems. According to the company, this model can understand information in a smarter way than the previous version.

Ability to do better with fewer tokens

According to OpenAI, GPT-5.4 is designed in such a way that it can produce better results even when using fewer tokens. This means both costs and processing time can be reduced for developers. This model has performed better in many benchmark tests. Especially in computer tasks, legal analysis and financial modeling, it has proven to be faster and more effective than earlier models.

New tool search system and safety test

With this new model, OpenAI has also introduced a new system called ‘Tool Search’. With its help, the AI model uses information from external tools only when needed, which saves tokens and makes the system work faster. The company has conducted new tests to improve the safety of the model. According to initial results, the probability of giving false information in GPT-5.4 has reduced compared to earlier models.
