OpenAI’s ChatGPT has experienced a surge in growth, reaching 400 million weekly active users by February 2025, according to a report from venture capital firm Andreessen Horowitz.
The AI chatbot, which took nine months to grow from 100 million to 200 million users in 2024, has now doubled its numbers in under six months. New AI model releases and enhanced functionality, such as GPT-4o’s multimodal capabilities and Advanced Voice Mode, have contributed to this accelerated adoption.
Mobile usage has played a crucial role in sustaining ChatGPT’s momentum, with mobile users growing consistently between 5% and 15% each month over the past year.
Of the 400 million weekly active users, 175 million now access ChatGPT via mobile devices. Despite growing competition, OpenAI’s chatbot remains the leading AI app in terms of unique monthly visits on the web and active users on mobile, according to market intelligence provider Similarweb.
Rival AI app DeepSeek has emerged as a strong competitor, quickly capturing 15% of ChatGPT’s mobile user base and ranking No. 2 globally within 10 days of launch. However, while DeepSeek has seen higher engagement than other competitors like Perplexity and Claude, it still lags behind ChatGPT overall.
The report also highlights AI developer tools, revenue trends, and the top generative AI apps across mobile and web.

Google has introduced an experimental version of its search engine that removes the traditional 10 blue links in favour of AI-generated summaries.
The new ‘AI Mode’ is available to subscribers of Google One AI Premium, a $19.99 per month plan, and can be accessed through a tab alongside existing options like Images and Maps.
Users will see a detailed AI summary with hyperlinks to cited sources, replacing standard search results with a search bar for follow-up questions.
AI Overviews, which provide summaries atop search results, are already available in over 100 countries, with advertisements integrated into them since last May. Google says the new AI-driven approach responds to demand from “power users” seeking more AI-generated responses.
As Google pushes deeper into AI-powered search, it faces competition from Microsoft-backed OpenAI, which introduced search capabilities to ChatGPT last October.
The shift has raised concerns among content creators, with edtech company Chegg suing Google in February, alleging that AI previews are reducing demand for original content and hurting publishers’ ability to compete.

The UK Competition and Markets Authority (CMA) has concluded its investigation into Microsoft’s partnership with OpenAI, deciding not to move forward with a merger probe.
The decision comes after the CMA found that Microsoft does not hold enough control over OpenAI, a key factor in triggering a merger review. The companies’ collaboration began in 2019, when Microsoft invested $1 billion in the AI startup.
Despite this, the CMA stated that Microsoft’s influence had not evolved to the level of de facto control required for further scrutiny.
This marks the end of the UK’s formal investigation into the deal, although the CMA clarified that its decision should not be interpreted as a dismissal of potential competition concerns related to the partnership.
While the investigation is closed, the CMA has been increasingly active in examining major tech company acquisitions, particularly those involving AI startups.
Microsoft welcomed the CMA’s decision, asserting that their ongoing partnership with OpenAI fosters innovation and competition in AI development.
Meanwhile, the CMA continues to monitor the tech sector, with broader powers to investigate companies deemed to hold ‘strategic market status’.

Microsoft’s UK boss has warned that many companies are ‘stuck in neutral’ when it comes to AI, with a significant number of private and public sector organisations lacking any formal AI strategy. According to a Microsoft survey of nearly 1,500 senior leaders and 1,440 employees in the UK, more than half of executives report that their organisations have no official AI plan. Additionally, many recognise a growing productivity gap between employees using AI and those who are not.
Darren Hardman, Microsoft’s UK chief executive, stated that some companies are caught in the experimentation phase rather than fully deploying AI. Microsoft, a major backer of OpenAI, has been promoting AI deployment in workplaces through autonomous AI agents designed to perform tasks without human intervention. Early adopters, like consulting giant McKinsey, are already using AI agents for tasks such as scheduling meetings.
Hardman also discussed AI’s potential impact on jobs, with the Tony Blair Institute estimating that AI could displace up to 3 million UK jobs, though the net job loss will likely be much lower as new roles are created. He compared AI’s transformative impact on the workplace to how the internet revolutionised retail, creating roles like data analysts and social media managers. Hardman also backed proposed UK copyright law reforms, which would allow tech companies to use copyright-protected work for training AI models, arguing that the changes could drive economic growth and support AI development.

US District Judge Yvonne Gonzalez Rogers ruled that Musk did not meet the high standards required to block the move. However, the judge indicated that she would expedite a trial on the matter, which is expected to take place later this year.
Musk, who co-founded OpenAI in 2015 but left before its major success, argued that OpenAI had initially sought his charitable funding to create AI for the public good, but has since shifted its focus towards making profits.
His lawyer, Marc Toberoff, expressed satisfaction that the judge had agreed to a swift trial, claiming that the case involves urgent public interest concerns.
OpenAI, which is seeking to become a for-profit entity to attract the necessary capital for its AI projects, welcomed the court’s decision.
The company emphasised that its goal is to develop advanced AI models to benefit society. Musk’s legal action, which also includes antitrust claims, stems from his frustration with OpenAI’s shift in direction since he departed from the organisation.

DeepSeek’s progress is a clear sign of the growing influence of Chinese companies in the AI sector, according to a spokesperson for China’s parliament. Lou Qinjian, speaking to reporters on Tuesday, praised the achievements of DeepSeek’s young team, describing their work as ‘commendable’.
He highlighted the company’s open-source approach and its efforts to spread AI technology globally, contributing ‘Chinese wisdom’ to the world.
The AI startup has been widely celebrated in China, particularly for rolling out AI models that offer a significantly lower cost than those developed by US rivals like OpenAI.
While some countries, including South Korea and Italy, have removed DeepSeek’s chatbot from their app stores over privacy concerns, it has been embraced within China, where local governments and tech firms are integrating it into their systems.
Based in Hangzhou, DeepSeek is rapidly advancing its next-generation model, set to succeed its R1 release from January, as it continues to make waves in the global tech sector.

OpenAI has rolled out a research preview of its latest GPT-4.5 model for Pro users, with plans to extend access to a wider audience over the next few weeks. The upgraded model boasts better pattern recognition, enhanced emotional intelligence, and an improved ability to generate creative insights.
The new version of GPT-4.5 also addresses a common issue with AI models, ‘hallucinations’ or the generation of false information, reducing its rate to 37.1%, compared to previous models’ higher rates. OpenAI’s CEO Sam Altman acknowledged some logistical challenges in the rollout, including GPU shortages, but assured users that more resources would be added soon.
While GPT-4.5 can handle tasks such as coding and content creation, it currently lacks some advanced features, such as voice and video capabilities. As OpenAI expands its offering, the company continues to refine the model to meet the growing demand for more powerful AI tools.

Baidu is set to launch the next generation of its Ernie AI model, the Ernie 4.5, in mid-March. This upgraded version will feature improved reasoning capabilities and enhanced multimodal functions, allowing it to process and integrate a variety of data formats, including text, images, audio, and video. Baidu also plans to make the Ernie 4.5 series open source from June 30, marking a significant shift in its approach to AI development.
The Chinese tech giant has faced fierce competition in the AI race, particularly from the rising startup DeepSeek, whose models are seen as rivals to leading US systems at a much lower cost. Despite claiming that Ernie’s performance is comparable to OpenAI’s GPT-4, Baidu has struggled to gain widespread adoption of its AI model. The emergence of DeepSeek has further complicated Baidu’s aspirations in the sector, leading the company to reassess its strategy.
Baidu’s CEO, Robin Li, who once advocated for keeping AI models closed-source, has acknowledged the success of DeepSeek and other competitors. He now views the open-source approach as essential for the future of AI development. This shift comes as Baidu continues to compete with other tech giants, including Alibaba, which recently announced its plans to make its video and image-generating AI model, Wan 2.1, open source.
