OpenAI launches $100‑per‑month ChatGPT Pro tier with expanded Codex usage

OpenAI rolled out a new subscription level for its ChatGPT product, priced at $100 per month and labeled the Pro tier. The plan offers five‑times the usage limits for Codex, the company’s code‑generation engine, than the $20‑per‑month Plus tier. OpenAI says the higher limits are meant for “longer, high‑effort Codex sessions,” a clear nod to professional developers and teams that rely on AI to write, debug, or refactor code.

The move comes as competition heats up in the AI coding space. Anthropic’s Claude Code Max, which also costs $100 a month, provides a comparable set of features for developers using the Claude model. By matching Anthropic’s price point and touting greater Codex capacity, OpenAI aims to keep its existing user base while attracting new heavy‑use customers.

OpenAI’s subscription lineup now includes five distinct tiers. New users can start with the free tier, which gives limited access to ChatGPT’s core features. An $8‑per‑month “Go” tier provides a modest boost in usage, while the $20 Plus plan remains the go‑to option for everyday conversational needs and moderate coding work. The newly announced $100 Pro tier sits between Plus and the existing $200 Pro offering, which continues to deliver the full suite of professional features without the usage caps of the lower tiers.

According to the company’s announcement, the $100 Pro tier does not strip away any existing Pro capabilities; it simply adds a higher ceiling for Codex interactions. “The new $100 Pro tier offers a more accessible upgrade path for heavier daily use,” OpenAI said, positioning it as the sweet spot for developers who need sustained AI assistance but do not require the full $200 commitment.

Industry observers note that the pricing structure reflects a broader trend of tiered AI services aimed at different user segments. By offering a mid‑range option, OpenAI can monetize power users without alienating hobbyists or casual users who are satisfied with the free or low‑cost plans. The strategy also helps the company diversify revenue streams as demand for AI‑driven development tools continues to rise.

OpenAI’s decision to expand Codex usage aligns with its long‑term goal of integrating AI more deeply into software development workflows. The company has previously highlighted the importance of “agentic newsroom” and “AI content generation” technologies for broader content creation, and the new tier underscores its commitment to delivering specialized AI tools for coding.

While the $100 Pro tier is the headline of the announcement, OpenAI emphasized that its existing subscription ecosystem remains intact. Users on the $20 Plus plan will continue to receive the “best offer for steady, day‑to‑day usage of Codex,” according to the company. Meanwhile, the $200 Pro tier still provides the highest level of access for enterprises and large teams that need unrestricted usage.

Analysts predict that the added tier could boost OpenAI’s subscription revenue in the coming quarters, especially as more developers adopt AI assistance in their daily workflows. The pricing parity with Anthropic’s Claude Code Max also sets the stage for a competitive showdown that could drive further innovation in AI‑assisted coding tools.

OpenAI has not disclosed how many users have already migrated to the new tier, but the company expects the offering to attract both existing Plus subscribers looking for more capacity and new customers evaluating AI coding solutions. The rollout begins immediately, with users able to upgrade through the ChatGPT interface.
