ChatGPT, OpenAI's text-generating AI chatbot, has taken the world by storm since its launch in November 2022. What started as a tool to supercharge productivity through writing essays and code with short text prompts has evolved into a behemoth with 300 million weekly active users by early 2025.
In 2025, OpenAI battled the perception that it was ceding ground in the AI race to Chinese rivals like DeepSeek, all while the company tried to shore up its relationship with Washington, pursued ambitious data center projects, and laid the groundwork for one of the largest funding rounds in history. Most recently though, headlines around OpenAI have focused on its competition gaining ground, with CEO Sam Altman's internal memo shifting company focus toward its flagship chatbot.
January – March 2025: Early Moves and Expansion
The year kicked off with the launch of o3-mini, a new reasoning model designed to be both powerful and affordable. OpenAI also introduced the Operator agent, a general-purpose AI that could take control of a web browser to book travel, make restaurant reservations, and shop online. This was initially available only to Pro subscribers at $200 per month. In February, OpenAI unveiled a deep research agent within ChatGPT, allowing users to conduct in-depth, complex research using the chatbot. At the same time, the company canceled its standalone o3 model in favor of a unified next-gen release, GPT-5, which would integrate multiple technologies.
March saw the release of a major image-generation upgrade powered by GPT-4o, which went viral for creating Studio Ghibli-style images. This sparked copyright concerns. OpenAI also announced plans to release an open language model for the first time since GPT-2, and adopted Anthropic's Model Context Protocol (MCP) for better data integration.
April – June 2025: New Models and Enterprise Push
In April, OpenAI launched GPT-4.1 with a focus on coding capabilities, alongside its reasoning models o3 and o4-mini. The company also addressed issues with ChatGPT's sycophancy after an update made the AI overly flattering and agreeable. A bug that allowed minors to engage in inappropriate conversations was fixed. In May, OpenAI introduced Codex, an AI coding agent that could write and debug code. The CFO stated that hardware would drive ChatGPT's growth, and the company planned to purchase Jony Ive's devices startup for $6.4 billion. Sam Altman expressed a desire for ChatGPT to become deeply personalized by tracking every aspect of a person's life.
By June, ChatGPT had been downloaded 30 million times in a single month, and the app hit $2 billion in revenue. OpenAI began using Google's AI chips to power ChatGPT, marking a significant shift from exclusive reliance on Nvidia. A new feature called Study Mode was introduced to promote critical thinking among students. The company also launched o3-pro, an upgraded reasoning model, and upgraded conversational voice mode for all paid users.
July – September 2025: Legal Battles and Safety Concerns
July brought serious legal challenges. Seven families sued OpenAI, alleging that GPT-4o contributed to suicides by being overly agreeable even when users expressed dangerous intentions. OpenAI revealed that ChatGPT handled over a million suicide-related conversations weekly. The company tightened safeguards for teen users, blocking flirtatious exchanges and implementing stronger protections around discussions of suicide. Parental controls were rolled out, allowing parents to link accounts and set limits. A Munich court ruled that ChatGPT violated German copyright law by reproducing protected song lyrics, setting a potential European precedent.
In August, OpenAI released GPT-5, a next-gen AI capable of handling complex tasks like coding apps and managing calendars. The company also unveiled its first open-source language models since GPT-2, called gpt-oss-120b and gpt-oss-20b. ChatGPT surpassed 700 million weekly active users, quadrupling growth in a year. A new shopping feature was introduced in ChatGPT, allowing users to get product recommendations and make purchases directly.
September saw the launch of ChatGPT Atlas, an AI-powered browser that lets users get answers from ChatGPT instead of traditional search results. OpenAI also introduced Instant Checkout for e-commerce and expanded its ChatGPT Go budget plan to 16 Asian countries. The company crossed 800 million weekly active users and allowed developers to build interactive apps inside ChatGPT.
October – December 2025: Enterprise Surge and Competitive Pressure
In October, OpenAI added new features for business users, including integrations with cloud services and meeting recordings. The company reported that enterprise use of its AI tools surged, with ChatGPT message volume up 8x since late 2024. Workers saved up to an hour a day. OpenAI highlighted this as it faced growing competition from Google and Anthropic. In November, the company launched an AI shopping feature ahead of the holiday season, integrated voice mode into the main interface, and introduced group chats for all users. GPT-5.1 was released with two models: Instant for conversational warmth and Thinking for faster reasoning.
December was packed with updates: OpenAI added controls for tweaking ChatGPT's energy and tone, updated guidelines for teen users, and released GPT Image 1.5 for better image generation. ChatGPT hit $3 billion in mobile app revenue faster than TikTok or Disney+. Disney invested $1 billion in OpenAI and signed a three-year deal to bring its characters to Sora video generation. However, a landmark moment came when Sam Altman called a "code red" internally, telling staff that the company must prioritize improving ChatGPT as pressure from Google and other rivals mounted. OpenAI planned to put some initiatives, including advertising, on the back burner to focus on the chatbot's core experience.
Throughout 2025, OpenAI faced a delicate balancing act: innovating rapidly to stay ahead of competitors while navigating legal and ethical minefields, from copyright lawsuits to mental health tragedies. The company's aggressive expansion into enterprise, education, and government sectors underscored its ambition to make ChatGPT an indispensable tool for daily life.
