AI Usage Limits & Pricing Tracker
September 2026

1. Subscription Plans at a Glance

Consumer plans only. Team and enterprise plans and API pricing are covered separately. Prices in USD, billed monthly.

2. Limit Structure by Service

ChatGPT (OpenAI)

• Pro tiers: Pro 100 is $100/month, Pro 200 is $200, and Pro 500 is $500. OpenAI describes Pro 200 as including more usage than Pro 100 and Pro 500 as the highest of the three.
• New subscriptions: Pro 200 subscriptions are available again. New subscriptions without grandfathering may receive a lower allowance than the earlier Pro 200 version.
• Ultrafast: included only with Pro 500 among Pro plans. At launch, buying credits on Pro 100 or Pro 200 does not unlock it.
• Credits and limits: credits support eligible usage in Codex, ChatGPT Work and certain document apps. They do not increase every model or feature allowance; check the account Usage screen for model-specific availability and reset times.
• GPT-5.5 retirement (complete): as scheduled, GPT-5.5 retired from ChatGPT, ChatGPT Work, and Codex across all plans on October 14, 2026 at noon PDT. The OpenAI API and API-key-authenticated Codex sessions are unaffected. The replacement default for Codex with ChatGPT sign-in is GPT-6.1 Sol.

Claude (Anthropic)

• 5-hour session limit: a rolling window from your first message. Doubled for Claude Code since May 6.
• Weekly cap: resets at a fixed day and time assigned to your account. All models share one pool; Fable 5.1 is capped at 50% of it on Max.
• When exceeded: wait, or buy usage credits at API rates. Claude Code can auto-continue a session once the limit resets.
• /limit-reset: a command that appeared for some accounts in early September. Clears the 5-hour session limit once a week (weekly cap unchanged). A/B tested, undocumented.

Gemini (Google)

• Expressed as plan multipliers (Plus 2x < Pro 4x < Ultra 5x/20x, vs. Free). Daily limits vary by model.
• Ultra adds Deep Think, the most compute-intensive models, and 35,000 AI credits.
• Model access change (now officially confirmed): per Google Help (17004136), the free plan has been limited to auto-selected Flash-Lite since Oct 9. AI Plus loses the ability to select Pro models starting November 13 (delayed from the initially announced Oct 9), leaving Flash and Flash-Lite. AI Pro and Ultra are unaffected and gain Gemini 4 Argon and Deep Think.

Grok (xAI)

• Restructured (2026.10.12): xAI retired separate SuperGrok and X Premium plans in favor of “The X Subscription,” which bundles Grok, Grok Bot, Cursor, and X into one plan. All new sign-ups start on this structure. Existing SuperGrok/X Premium subscribers can keep their current plan or switch (with a prorated refund); switching is optional.
• Grok, Grok Bot, and Cursor share one weekly usage pool. Grok Bot is included from Premium up; the Plus tier does not include it.
• Reset is a weekly schedule attached to your account, shown in Settings > Usage. When empty: buy top-up credits or upgrade.

6. FAQ

When does my Claude limit reset?

Two clocks run separately. The 5-hour session limit clears five hours after your first message; the weekly cap clears at a fixed day and time assigned to your account. See the exact time at claude.ai/new/usage.

Can I subscribe to ChatGPT Pro 200 now?

Yes. OpenAI Help checked October 3, 2026 says new Pro 200 subscriptions are available again. A new subscription without grandfathering may receive a lower allowance than the earlier version.

Can Pro 100 or Pro 200 use Ultrafast?

No. Ultrafast is included only with Pro 500 among the Pro plans. At launch, buying credits on Pro 100 or Pro 200 does not unlock it.

Do purchased credits increase every ChatGPT limit?

No. Credits support eligible usage in Codex, ChatGPT Work and certain document apps. They do not add usage to every model or feature.
