OPENAI Cat exceeded 400 million weekly active usersA milestone that underlines the growing scope of the company on the consumer and companies markets, according to an X post of the director of the Brad Lightcap Operation on Thursday.

Rapid expansion occurs while Openai faces the intensification of rivals like Elon Musk xai and China In depthBoth recently launched very efficient models aimed at disturbing the domination of Openai. Despite this, Openai has experienced a significant traction in the business sector, with more than two million business users who now use Chatgpt at work – dubbing compared to September 2024.

“Chatgpt recently crossed 400m Wau, we feel very lucky to serve 5% of the world every week,” wrote Lightcap. He also noted that the use of Openai Reasoning model API has made a five -time since the launch of its Mini model O3which is designed to improve logical inference and structure problem solving capacities.

AI reshapes the workplace: 2 million companies now count on Chatgpt

The increase in the adoption of companies represents a crucial validation of the OPENAI strategy to position Chatgpt as not only a chatbot for occasional requests, but as a serious productivity tool for companies. Companies such as Morgan Stanley,, Uber And Mobile have integrated OPENAI models into their workflows, using AI to generate reports, automate customer service and rationalize decision -making.

In particular, OpenAi’s progress occurs in the midst of an in -depth examination on the role of generative AI in critical applications. The company recently obtained its first federal agency client, Usaidunfolding Enterprise chatgpt To reduce administrative charges and rationalize partnerships, according to Fedscoop. Expansion in government contracts suggests that Openai succeeds in navigating the regulatory obstacles that have slowed the adoption of AI in public sector institutions.

At the same time, Openai deepens his presence in Japan through a joint venture With SoftBank, doubled SB OPENAI Japan. The partnership, which implies an annual investment of $ 3 billion in softbank, aims to integrate OpenAi technology into large Japanese companies, with initial deployments within the SoftBank ecosystem, including its semi subsidiary -Conductor Arm and digital payment platform Paypay.

GPT-5 arrives: the next Openai jump in artificial intelligence

Lightcap also revealed that Optai is preparing to launch GPT-4.5 and GPT-5, this last set to merge the GPT and O-Series models of the company in a unique and more powerful system.

“We will bring GPT-4.5 and GPT-5 to discuss and the API soon, with an unlimited GPT-5 for free users (the more users can operate even higher intelligence),” he wrote.

This movement signals the OPENAI’s ambition to consolidate its AI offers in a unified model which can manage both the general tasks of the IAI and the applications more based on specialized reasoning.

By integrating the capacities of its GPT flagship models to solving structured problem of the series O, OpenAi bets that an approach to a modeling at Rule-Tout will give it a competitive advantage over rivals that are still segmented their IA offers .

OPENAI roadmap update for GPT-4.5 and GPT-5:

We want to do a better work to share our planned roadmap, and a much better work simplifying our product offers.

We want AI to “work just” for you; We realize how complicated our model and product offers.

We hate …

The time of the GPT-5 version is particularly critical. The Musk XAI recently introduced Grok 3, a model which, according to the company, surpasses the GPT-4O of Openai in certain benchmarks, including mathematics, sciences and coding. Meanwhile, the rapid rise of Deepseek in China added to the pressure on Openai to maintain its advance in the sophistication and accessibility of the AI.

AI wars: Openai, Xai and Deepseek Battle for Global Dominance

Openai’s expansion occurs at a time of fierce competition in the AI ​​sector, with rival companies that were running to guarantee market share in consumption and business applications.

Musk, who co -founded Openai before leaving in 2018, expressed his concerns about the company’s transition to a for -profit model. The billionaire recently launched a $ 97 billion offer To take control of Openai, a decision that was rejected quickly by the company’s board of directors. OPENAI has since positioned itself as the leader in corporate AI deployments, Microsoft’s support offering both financial stability and cloud infrastructure.

Meanwhile, Deepseek disrupted the market with low-cost open-source IA models that have gained ground, especially among the developers suspicious of the Openai pricing model. The Chinese company said it has formed its latest model for less than $ 6 million – an order of magnitude lower than Optaai and Xai spend for comparable systems.

What is the next step for Openai? The future of AI in business and beyond

The latest OPENAI user measures suggest that the company is still developing in rapid clip despite increasing competition. The jump from 300 million to 400 million weekly active users in just three months indicates that the demand for tools fueled by AI continues to grow, companies integrating them more into their daily operations.

Launching GP-5 will be a crucial test of OpenAi’s ability to maintain its leadership in AI. If the model holds the promises of higher reasoning capacity, better personalization and better efficiency, it could constitute the OPENAI position as an essential supplier for consumer and business AI applications.

However, with musks xai,, In depth And google Gemini Models in the running for domination, Openai cannot afford to slow down. The next 12 months will probably determine whether it remains the undisputed leader of the generative AI, or if a new player will disturb the balance of powers in artificial intelligence.
