Microsoft engineers are boosting infrastructure capacity to prepare for the latest version of OpenAI's large language model, the first version may be implemented by the end of February.

Sources close to Microsoft revealed to The Verge's Tom Warren that the software giant plans to launch OpenAI's latest GPT-4.5 as early as next week.

OpenAI CEO Sam Altman recently revealed that the company plans to release GPT-4.5 next time , but no specific date is provided.

Although GPT-4.5 is described as a "mid-term" update, OpenAI has been reported to have been training models using synthetic data, which, according to IBM, can overcome data scarcity when training and fine-tuning AI models.

In addition to the expected GPT-4.5 to be released soon, sources at The Verge also said that Microsoft is expected to receive the more powerful GPT-5 by the end of May.

Altman describes GPT-5 as “a system that integrates many of our technologies, including o3,” referring to OpenAI’s latest inference model. On January 31, the company released a smaller o3 model called the o3-mini.

Microsoft currently hosts OpenAI models on its Azure platform. However, Microsoft clarified that the service will not interact with any tools operated by OpenAI, including ChatGPT.

Microsoft and OpenAI expanded their partnership last month through Stargate, a $500 billion AI joint venture by U.S. President Donald Trump.

Microsoft said OpenAI also "made a new, huge Azure commitment to continue supporting all OpenAI products and training."

The AI ​​competition heats up

Since its launch in November 2022, ChatGPT has set a record for the fastest growing consumer software platform in the world. According to Brad Lightcap, OpenAI chief operating officer, it had accumulated about 400 million weeks of active users as of February 2025, up 33% in less than three months.

According to CNBC, this amazing increase allowed OpenAI to seek financing at a valuation of $340 billion.

However, competition is heating up with the recent launch of DeepSeek, an open source AI model derived from China that costs only a fraction of ChatGPT’s development.

The launch of DeepSeek threatens the mainstream paradigm where OpenAI and the United States will continue to dominate the AI ​​market.

Venture capitalist Marc Andreessen calls DeepSeek the “Sputnik moment of artificial intelligence”, referring to society’s awareness of the need to catch up with the rapid technological developments in the rest of the world.

The market certainly responded to this collective awe as tech stocks, bitcoin and the wider cryptocurrency market plunged after the launch of DeepSeek.
