OpenAI has explored introducing advertisements into ChatGPT to generate revenue beyond subscriptions and API usage, given the high cost of running AI models. CEO Sam Altman has indicated a willingness to consider ads if they enhance user experience rather than intrude, though he previously called them a "last resort." Recent reports suggest advertising initiatives are being delayed as the company prioritizes improving ChatGPT's core features and competitiveness, despite hiring for ad-tech roles and building supporting infrastructure.
