OpenAI has announced a new version of its ChatGPT Pro subscription that costs $100 per month. The new Pro tier offers “5x more” usage of its Codex coding tool than the $20 per month Plus subscription and “is best for longer, high-effort Codex sessions,” OpenAI says.

The company is introducing the new tier as it tries to win over users from Anthropic and its popular Claude Code tool. ChatGPT’s $100 per month option will directly compete with Anthropic’s “Max” tier for Claude, which costs the same price. It also offers a middle ground between the $20 per month Plus tier and the $200 version of the Pro tier.

(Yes, there are now two tiers of “Pro”; while the new tier “still offers access to all Pro features,” OpenAI says that the more expensive one has even higher usage limits.)

According to OpenAI, ChatGPT Plus will “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.” OpenAI also offers an $8 per month Go tier and a free tier.
