OpenAI has expanded access to ChatGPT for free users by enabling unlimited text conversations and introducing a new 'think' button feature designed to help the AI work through complex queries more effectively. The feature rollout includes both free-tier and Go subscription users, representing a significant enhancement to the free ChatGPT experience.
Why it matters: This move democratizes access to advanced AI capabilities and could reshape the competitive landscape by making reasoning features available to millions of free users, forcing competitors to reconsider their own free-tier offerings.
