OpenAI has launched a new $100 monthly subscription plan for its ChatGPT product, aimed at users with intensive usage needs, particularly in coding. This new tier fills a gap in OpenAI's pricing structure, which previously offered plans ranging from a free tier to a $200 Pro plan. The $100 plan allows users to access Codex, OpenAI's coding-focused AI tool, with five times the usage compared to the $20 Plus plan, making it ideal for developers with high workloads. The introduction of this plan is a strategic move to compete with other AI services, such as Anthropic's Claude AI, which also offers a $100 monthly plan. OpenAI has reported a surge in demand for its Codex tool, with over three million users weekly, reflecting a 70% month-on-month increase. Users subscribing to the new plan will enjoy enhanced Codex usage limits until May 31, although all plans come with preset rate limits. This initiative aims to provide a balanced option for users needing more power without the commitment of the highest tier.
