OpenAI Launches $100 ChatGPT Pro Tier for Developers

OpenAI launched a new ChatGPT Pro subscription tier priced at $100 per month to bridge the pricing gap between its $20 Plus plan and a high-end $200 Pro plan. The new tier specifically targets developers and heavy users of Codex, offering five times the usage limits of the Plus plan and access to GPT-5.4 Pro. As a temporary promotion through May 31, users on the $100 plan will receive ten times the Codex capacity of the Plus tier.

This strategic shift follows a fivefold increase in Codex usage, which now exceeds 3 million weekly users. By introducing this tier, the company directly competes with Anthropic, which offers a similar $100 monthly plan for its Claude AI service. To encourage power users to migrate, OpenAI is ending a temporary Codex promotion for Plus users, repositioning that tier for steady daily use rather than high-intensity bursts.

Beyond pricing, the company upgraded its background fallback model to ChatGPT-5.3 Instant Mini, replacing GPT-5 Instant Mini for users who hit rate limits. OpenAI also rolled out a voice-first ChatGPT experience for Apple CarPlay for users on iOS 26 and above. The company further reported that enterprise adoption now accounts for more than 40% of its total revenue.
