If ChatGPT’s $20-a-month Plus plan is cramping your style but the $200-a-month Pro plan sounds like overkill, there’s growing evidence of a cheaper ChatGPT Pro tier that would split the difference. An AI developer poking around ChatGPT’s web app code recently found a “checkout page” string that references a “ChatGPT Pro Lite” plan, with the price pegged at $100 a month. The checkout string has yet to be activated. The plan description on a subsequent checkout page merely details the existing ChatGPT Pro plan but is “likely still a work in progress,” developer Tibor Blaho noted on X . Checking the ChatGPT web app code for myself on Monday, I too found several references to “PROLITE” and “chatgptprolite” on ChatGPT’s plan pricing page . Blaho, a lead engineer for prompt management tool AIPRM, had previously found hidden code suggesting that ads were coming to ChatGPT , which turned out to be true. I’ve reached out to ChatGPT parent OpenAI for comment. OpenAI currently offers four personal ChatGPT tiers, including a $20-a-month Plus plan and ChatGPT Pro for a much pricier $200 a month. There’s also the recently-launched $8-a-month Go plan and a free tier, both of which may serve ads along with ChatGPT’s responses. ChatGPT Plus typically gives regular users enought headroom for everyday tasks and chats, including image and video generation, memory of past conversations, and the ability to create custom GPTs. But more ambitious users and Codex-using vibe coders may quickly find themselves hitting ChatGPT’s usage limits. For them, the only option is a massive jump to the far pricier ChatGPT Pro tier. A $100 ChatGPT Lite would offer some much-needed middle ground between the $20-a-month ChatGPT Plus plan and the $200/month ChatGPT Pro tier. Gemini users are in a similar boat with Google’s AI plans, with a wide gulf between Google AI Pro for $20 a month and Google AI Ultra for a whopping $250 a month. Google also offers a paired-back AI Plus plan for $8/month and a free tier, similar for ChatGPT’s cheaper options. In contrast, Anthropic’s Claude does boast a middle ground for its pricier plans, with Claude Max offering a Max 5x tier (with roughly five times the limits of the $20-a-month Claude Pro plan) for $100 a month, while a Max x20 plan goes for $200 a month.
