ChatGPT's Monthly Growth Again Tops 10%... Altman Says "New Chatbot Model Coming This Week"

OpenAI's ChatGPT, which had lost momentum after being overshadowed by Google's Gemini and Anthropic's Claude, has once again recovered double-digit monthly growth.

According to CNBC on the 9th (local time), Sam Altman, Chief Executive Officer (CEO) of OpenAI, recently told employees via an internal messenger that "ChatGPT's monthly growth rate has once again exceeded 10%."

CEO Altman said that, in particular, since the launch of the coding-focused AI model "GPT-5.3 Codex" on the 5th, usage of Codex has increased by 50% in just one week. He described Codex's growth trajectory as "insane" and called it "an incredible week."

CEO Altman also announced the launch of a new chatbot model. He said, "We are preparing to launch a new chatbot model this week." The new model is expected to be the chatbot version of "GPT-5.3 Codex" and a model that has been in the works since the "code red" emergency alert was issued last year.

Earlier, at the end of last year, OpenAI issued an internal code-red alert as it came under pressure from Google's Gemini and Anthropic's Claude. CEO Altman asked team members to put other projects on hold for a while and focus on improving ChatGPT and other AI models. As a result, the company moved up the launch schedule for "GPT-5.2" by several weeks and released it on December 11 last year.

Meanwhile, OpenAI is also in the final stages of an investment round worth 100 billion dollars (about 145 trillion won). Sources said that OpenAI is emphasizing to investors participating in this funding round that its coding model "Codex" is eroding the market share of Anthropic's "Claude Code," which has so far been strong in the enterprise AI market.

This investment round by OpenAI closed its first phase with Microsoft (MS), Nvidia, and Amazon. CNBC reported that additional investments are expected to follow from other participants, including SoftBank, which is in talks to invest 30 billion dollars.
