OpenAI now allows users to access ChatGPT for free without creating an account. Premium products like GPT-4 Turbo require a subscription. ChatGPT based on GPT 3.5 can be used without an account, but advanced versions need an account and payment.
OpenAI also sparked a deal last year with venture capital firms Thrive Capital, Sequoia Capital, Andreessen Horowitz, and K2 Global. The deal led to a rise in the company's valuation to $29 billion.
