OpenAI launched a new $100/month ChatGPT Pro tier on April 9, 2026, positioned between the $20 Plus and $200 Pro plans. The new tier offers 5x more Codex usage than Plus (temporarily 10x through May 31), with access to the same GPT-5.4 model suite as the $200 plan. The move directly targets Anthropic's Claude Max at the identical $100 price point, which includes elevated limits for Claude Code. The timing follows Codex reaching 3 million weekly users with 70% month-over-month growth. OpenAI's strategy reflects a bet on autonomous, long-running agentic coding workflows as the next phase of developer adoption, filling a pricing gap for heavy users who outgrow Plus but don't need the full $200 tier.
