Generative pretrained transformers, also known as GPTs, represent a part of the family of large language models (LLMs). Powering ChatGPT and other generative AI applications, these foundation models were developed by OpenAI and can imitate content created by humans. GPT versions work on a transformer framework that leads to accelerated generative AI development.

GPT can be used for voice assistance and virtual assistant, code generation, text writing, language translation, data tracking, document summarization, and even healthcare. It works by analyzing a sequence and applying mathematics algorithms to anticipate the most likely response.

The GPT models are powered by two major factors: generative pretraining (trains the model to find patterns in unlabeled information and apply them to inputs) and a transformer architecture (permits the model to study all portions of an input sequence in parallel).

ICT Industry in Japan: General Profile and Insights

The Information and Communications Technology (ICT) industry in Japan is touted to be the top industry in the country. In 2018 this sector was worth USD 2.2 trillion. The Japanese government aims to take this number to 3.4 trillion by 2025.

In fact, with the government steadily coming up with innovative ideas and efforts to significantly impact and contribute on a global scale, the industry is expected to exceptionally boom in the upcoming years. Both the public and the private sectors are aware of the importance of the latest, most innovative ICT solutions to advance the economy and are taking steps towards this. Hence, this sector holds immense business potential.

Why working with Japanese IT companies

Based on the country data of Japan, there are various opportunities in the ICT Sector. Firstly, the country ranks 3rd as the biggest market with average revenue per user in Asia. This means that local IT companies from Japan have adopted a mixed business model, and adjusted it under both local and international IT market requirements. Shortly, Japanese IT companies approach international and local clients differently keeping the longstanding business tradition but at the same time offering high-quality services and digital products to foreign markets under the rules of Western business style. 

What to be aware of when working with Japanese IT companies

Since tech giants established business connections in Japan, local IT companies faced the need of changing and adjusting their approach to international requirements, ending the era of a “closed market”. This has brought both benefits and challenges for Japanese IT companies and web and software providers. 

The biggest challenge still remains the human resources for IT companies, since the legislation does not allow outsourcing professionals from other countries and rely only on native talents. Taking into consideration the demographics and the continuously ageing population, fewer young professionals are enrolled in the IT sector, which automatically means less flexibility and capacity to adopt new technologies and implement them into local digital business environments. 

How reliable are Japanese IT companies

Japan has built a reputation for its highly skilled professionals and trustworthy country, especially after WWII, when the US invested and developed under its umbrella the Japanese business environment. The Japanese IT companies, web and software agencies take full advantage of this position by promoting their services and digital products on the international market. 

How does the Japanese IT industry relate to the neighboring countries

Japan has probably the most developed IT industry in the region and a proven high potential for providing the entire spectrum of ICT services at the highest quality. Nonetheless, South Korea and China are coming close to the 2nd and respectively 3rd position in terms of IT industry and infrastructure development. 

What is GPT and what are its benefits for your projects?

Generative pretrained transformers, also known as GPTs, represent a part of the family of large language models (LLMs). Powering ChatGPT and other generative AI applications, these foundation models were developed by OpenAI and can imitate content created by humans. GPT versions work on a transformer framework that leads to accelerated generative AI development. 

GPT can be used for voice assistance and virtual assistant, code generation, text writing, language translation, data tracking, document summarization, and even healthcare. It works by analyzing a sequence and applying mathematics algorithms to anticipate the most likely response. 

The GPT models are powered by two major factors: generative pretraining (trains the model to find patterns in unlabeled information and apply them to inputs) and a transformer architecture (permits the model to analyze all portions of an input series in parallel). 

What are the perks of using GPT for your project?

GPT has a big influence on how machines create content like humans and has expanded the limits of natural language processing. The latest version is GPT-4 and was created to outdo diverse tasks related to languages and has abilities in understanding and creating human text. Your project can leverage the benefits GPT offers, and they are the following:

  • Context understanding
  • Generating more detailed responses
  • Versatile
  • Higher accuracy rate
  • Vast applications
  • Used in customer support
  • Advancements in language translation

How to choose the best GPT platform?

Finding the right partner for your project that offers GPT services is an important task. The selection should be done considering the project’s type and requirements, budget, deadlines, and others, including:

  1. Specify your project’s case fit: it can be content creation, code writing, customer support, research, and many more. 
  2. Look for a platform that has the latest versions of GPT, like GPT-4o and GPT-4.5, for more features and better results.
  3. Find a GPT platform that can easily integrate with your used tools, for example, Google Workspace, Slack, or one that offers APIs for easy insertion into your applications. 
  4. Your budget considerations are important, so select a platform that has affordable prices with the required features for your project. 
  5. Find a platform with a strong community that provides help and support to avoid issues or resolve them as they appear.
