OpenAI adds $100 tier
OpenAI introduced a new $100-per-month ChatGPT Pro tier positioned between the $20 Plus plan and higher-end offerings, pitching substantially more Codex access for heavy coding users. The company also reshuffled ChatGPT’s internal model lineup and made fallback routing explicit—paid users can fall back from GPT-5.4 Thinking to GPT-5.4 mini and enterprises can set Auto routing defaults, according to OpenAI release notes.

OpenAI has added a new $100-a-month ChatGPT Pro plan aimed at people who use its coding tool Codex heavily. (help.openai.com) OpenAI’s Help Center says the new tier sits between Plus at $20 a month and the existing Pro plan at $200 a month. The company says the $100 plan includes unlimited access to GPT-5.4, access to GPT-5.4 Pro, and higher allowances for tools including Codex and Deep Research. (help.openai.com) For coding, the pitch is usage. OpenAI says the $100 plan comes with 5 times the Codex usage of Plus as a standard allowance, and the current promotion raises that to as much as 10 times through May 31, 2026. (help.openai.com, developers.openai.com) Codex is OpenAI’s coding agent, a tool that can generate, edit, and work through programming tasks across longer sessions. OpenAI says it is included with Plus, Pro, Business, Enterprise, and Edu plans, but the new pricing tier is built around giving developers longer and more parallel sessions before hitting limits. (help.openai.com, community.openai.com) The plan change arrives as OpenAI is also reshaping the model menu inside ChatGPT. OpenAI says GPT-4o, GPT-4.1, GPT-4.1 mini, OpenAI o4-mini, and the older GPT-5 Instant and GPT-5 Thinking options were retired from ChatGPT on February 13, 2026. (help.openai.com) In their place, OpenAI has centered ChatGPT around GPT-5.3 and GPT-5.4. The company introduced GPT-5.4 in ChatGPT on March 5, 2026, describing it as its model for professional work, with stronger coding, tool use, and a context window of up to 1 million tokens. (openai.com, help.openai.com) OpenAI also made fallback behavior more explicit. Its model release notes say paid users who hit rate limits on GPT-5.4 Thinking are automatically routed to GPT-5.4 mini so reasoning features stay available during heavy usage. (help.openai.com) For companies, the routing controls are broader. OpenAI says Enterprise customers can choose GPT-5.4 mini as the default for Auto routing, which lets administrators trade some capability for lower cost or higher throughput across a workspace. (help.openai.com) The move also puts OpenAI closer to rivals that already sell premium coding-focused subscriptions. TechCrunch and CNBC both reported that OpenAI is positioning the new tier against Anthropic’s $100 Claude Max offering as demand for AI coding tools rises. (techcrunch.com, cnbc.com) OpenAI is not adding a separate new product so much as charging for more headroom. The company’s own pricing pages describe the $100 plan as the same ChatGPT stack with more room for long coding sessions, while the $200 plan remains the highest-usage option.
