From December, ChatGPT joins the other two. I read all three vendors’ help pages, and they’ve ended up in a very similar place. ChatGPT: starting in December, the allowance on Plus, Pro and Business is shared across ChatGPT and Codex and measured in tokens. Instant chat doesn’t count. Settings > Usage shows what’s left and when it resets. Claude: on paid plans, a session limit resets every five hours, plus weekly limits. Usage depends on conversation length and complexity, features, model and effort level. Claude.ai and Claude Code draw from the same limit. Anthropic also says it may adjust limits “at our discretion.” Gemini: “compute-based usage limits” that refresh every five hours until you reach a weekly limit. AI Plus is “2x higher than standard limits” and AI Pro is “4x.” The page doesn’t put a number on “standard.” Google does at least publish a table of relative cost, from “Very low” for a short prompt to “High” for Deep Research and video. So you get a gauge, but no price per unit. You can see what percentage is left of an amount nobody has stated, and you only learn what a task uses after you’ve run it. A phone plan at least tells you it’s 50 GB and roughly what a video eats. Here, “4x” of an undefined number can’t be compared across vendors, and you can’t plan a busy week around it. I get why they do it. A one-line question and a long chat with tools really do cost wildly different amounts to serve, and vague limits leave them room to manage capacity. But the uncertainty lands on the people paying, and it matters more as these tools move from something you try into something your workday depends on. Until that changes, you can measure it yourself. Note the percentage, run a typical task, and note it again. Then try the same task in a fresh chat and in a long one. Do that a few times and you’ll have better numbers than any of the help pages give you. I build AI Toolbox, a browser extension for desktop, and it puts Gemini’s and paid Claude’s own usage figures and reset times in a bar under the message box, for free. That saves opening Settings, but it can’t tell you what your next message will use either, because the vendors don’t publish that. Would you take a smaller allowance if it came with real, published numbers? Or is the flexibility worth not knowing? submitted by /u/Ok_Negotiation_2587
