ChatGPT has once again captured the spotlight with a phenomenal growth spurt. According to a new report by venture capital firm Andreessen Horowitz (a16z), ChatGPT soared to new heights during the second half of 2024, doubling its user count in less than six months. This remarkable boost comes on the heels of several innovative feature releases and model upgrades, underscoring the platform’s ongoing appeal to users worldwide.
From Record-Breaker to Household Name
Shortly after its release in November 2022 as an experimental research preview, ChatGPT astonished the world by becoming the fastest app in history to gain 100 million monthly active users. It reached that milestone within just two months. By November 2023, the AI chatbot had soared to 100 million weekly active users—a figure that surged to 300 million by December 2024, and then 400 million by February 2025.
Today, those numbers have climbed even higher. While it initially took ChatGPT nine months to expand from 100 million weekly active users to 200 million (between November 2023 and August 2024), the next doubling happened in less than six months, according to a16z’s analysis. This trajectory demonstrates the intense user demand and the evolving ways people are integrating ChatGPT into their daily routines.
Novelty vs. Everyday Utility
In its early days, ChatGPT attracted attention largely due to its novelty. People were curious and wanted to see what this new AI tool could do—whether it was writing short stories, solving math problems, or producing creative text responses. However, many of these initial users weren’t yet convinced it could become part of their daily workflow.
Fast-forward to 2024, and the picture has drastically changed. Thanks to continuous refinements, ChatGPT now powers a range of use cases, from academic research to personalized content creation. This shift from mere curiosity to everyday practicality has played a pivotal role in fueling ChatGPT’s escalating adoption.
What Sparked the Recent Growth?
According to a16z, there’s a clear correlation between the introduction of new models and functionalities and ChatGPT’s user growth spikes. One key example is GPT-4o, which added multimodal capabilities in early 2024. This allowed the chatbot to handle not just text queries but also various other input types, prompting a wave of renewed interest between April and May 2024.
Another major milestone was the arrival of Advanced Voice Mode in mid-2024. Users suddenly had the option to converse with ChatGPT using voice commands—something that made the experience more intuitive and convenient. The o1 model series, launched in the fall of 2024, further sharpened ChatGPT’s reasoning and creative writing prowess, driving additional expansion from September through October.
Consistent Growth on Mobile
While growth on desktop saw occasional surges, ChatGPT’s mobile usage charted a steadier path of upward momentum. According to a16z’s data, the chatbot’s mobile user base has steadily increased by 5% to 15% each month. Out of ChatGPT’s total 400 million weekly active users, 175 million now access the service through their smartphones or tablets. This statistic underscores how crucial mobile accessibility is to maintaining user engagement.
Facing Stiff Competition: DeepSeek and Beyond
It’s not just ChatGPT that’s enjoyed time in the AI spotlight. Rival platforms have also made big strides, most notably DeepSeek. The app climbed to the No. 2 spot worldwide in a mere 10 days, grabbing 15% of ChatGPT’s mobile user base. It even surpassed other AI contenders like Perplexity and Claude in user engagement, though it still trails ChatGPT’s broader reach.
The race among AI chat platforms is intensifying, which can spur faster innovation for users. DeepSeek’s rapid adoption might be a sign that the market has room for multiple AI apps that cater to slightly different needs or preferences. Even so, ChatGPT remains the top choice for millions of people looking for fast, reliable, and versatile AI-generated responses.
More Insights for AI Enthusiasts
Besides highlighting ChatGPT’s strong performance, the a16z report offers insights tailored for AI developers and coders. It features a curated list of top AI tools for smoother app development, plus rankings of the leading AI-powered applications by category and revenue. In these rankings, ChatGPT retains its No. 1 position by unique monthly visits (web) and monthly active users (mobile), according to data from analytics provider Similarweb.
This leadership solidifies ChatGPT’s status as a front-runner among GenAI apps, indicating it has both the brand recognition and the technical muscle to remain a dominant force. As AI continues to evolve, the chatbot’s developer community can expect an even richer ecosystem of third-party plugins and integrations, potentially broadening ChatGPT’s capabilities even further.
The Future of ChatGPT: More Innovation Ahead
Given its momentum and track record, ChatGPT is likely to keep introducing fresh features that set it apart from the competition. New functionalities, like expanded knowledge domains or enhanced creativity modes, could be just around the corner. These updates not only attract newcomers but also keep existing users engaged, reinforcing ChatGPT’s position as a must-have AI tool.
However, it’s equally important to note that competition in the AI space is fierce. DeepSeek’s rapid growth may serve as a wake-up call, encouraging ChatGPT to continue pushing boundaries. Whether through deeper language understanding, improved voice interaction, or further expansion into specialized tasks, ChatGPT’s best bet is to stay on the cutting edge of AI developments.
