OpenAI looks to take on Anthropic with $100 per month ChatGPT Pro subscriptions

OpenAI announced a Pro ChatGPT tier on Wednesday that increases limits for Codex, OpenAI's artificial intelligence-powered coding assistant, as the company looks to compete with Anthropic's popular Claude Code.In an announcement posted to X, the company said the $100 per month Pro tier has five times more Codex usage than its $20 per month Plus level, and is best for "longer, high-effort Codex sessions." "The Plus plan will continue to be the best offer at $20 for steady, day-to-day usage of Codex, and the new $100 Pro tier offers a more accessible upgrade path for heavier daily use," the company wrote in a post on X.The new level brings the number of ChatGPT subscription tiers to five for personal use: Free, Go, Plus and now two Pro levels. OpenAI already had a $200/month Pro tier.Anthropic, which launched Claude Code to the public in May 2025, has a similar subscription tier model with four fee levels, starting with Free. Its highest tiers, Max 5x for $100/month and Max 20x tier for $200/month, have higher limits for Claude Code usage than its Pro subscription.The coding assistant can automate tasks and bug fixes for software developers and has soared in popularity. The run-rate revenue for the tool was over $2.5 billion in February, increasing over 100% since the beginning of 2026, CNBC previously reported.OpenAI launched Codex initially last April, and made it widely available in October. On Tuesday, CEO Sam Altman posted on X that Codex had three million weekly users, and the company would reset usage limits every million users until the platform hits 10 million.In February, the company launched a standalone Codex app for Apple computers in a push to gain more users as AI coding tools continue to gain popularity.Got a confidential news tip?
