OpenAI founder Sam Altman has announced that ChatGPT, the company's popular AI chatbot, has regained a monthly growth rate exceeding 10%. This development comes as OpenAI faces competitive pressure from Anthropic's enhanced coding tools. In a message to employees, Altman highlighted the company's momentum, noting that OpenAI plans to launch an upgraded chat model this week. Additionally, OpenAI's coding product, Codex, has seen a 50% growth increase compared to the previous week, marking a significant achievement for the company.
