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

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.
