# Fuel: every AI plan in one figure > Shuriken adds up your Claude and Codex plans as fuel, where 100 is a Max 20x, per provider and per limit: one figure for what's left across every account. Source: https://shuriken.sh/features/fuel 100 fuel is one Claude Max 20x's limit, every 5 hours or every week, and a Pro counts 5 every 5 hours. Shuriken adds up the fuel your subscriptions have left, one figure per provider and per limit, in the top bar. [Download](https://shuriken.sh/download) [Pricing](https://shuriken.sh/pricing) The problem ## Percents from different plans don't add up. Claude reports each account's use as a percent of that account's own plan. 40% of a Pro and 70% of a Max 20x are different amounts, so with three or four accounts there is no honest total of what's left. Codex sizes its plans another way again, and a Claude chat can't run on a ChatGPT plan anyway. Adding everything into one percent would only make a bigger wrong number. How Shuriken handles it ## How it works ### A Max 20x is 100 fuel. 100 fuel is a whole Max 20x limit, in the 5 hours and in the week alike. For Codex, 100 is about one ChatGPT Pro's week, and a Plus counts 20. ### Smaller plans are a slice. A Pro counts 5 every 5 hours and about 17 a week. A Max 5x counts 25 and about 58. ### Your sources add up. Three Pros and a Max 20x make 115 every 5 hours and about 150 a week: one figure per limit. ### Each provider on its own. A Claude chat can't run on a ChatGPT plan, so the top bar shows the figure for the chat's provider. ## How your sources add up. Every source is a tank on its provider's scale: a full tank is 100 fuel, one Max 20x or one ChatGPT Pro, and a Claude Pro is a small slice of it. Shuriken adds a provider's tanks into one figure per limit, and keeps Claude and Codex apart. Claude: three Pros at 5 each and a Max 20x at 100 add up to 115 fuel every 5 hours. Codex, counted apart: a Plus adds 20; a Pro has no 5-hour limit. Claude: three Pros at about 17 each and a Max 20x at about 100 add up to ≈150 fuel a week. Codex, counted apart: a Plus and a Pro add up to ≈120. ### Plan sizes, in fuel Each plan's size in fuel, per limit | Plan | 5-hour | Week | | --- | --- | --- | | Claude Pro | 5 | ≈17 | | Claude Max 5x | 25 | ≈58 | | Claude Max 20x | 100 | ≈100 | | Claude Team Standard | 6.25 | ≈21 | | Claude Team Premium | 31.25 | ≈104 | | Claude Enterprise | ≈5 | ≈17 | | ChatGPT Plus | 20 | 20 | | ChatGPT Business | 20 | 20 | | ChatGPT Pro | No 5-hour limit | ≈100 | | ChatGPT Enterprise | ≈20 | ≈20 | | ChatGPT Edu | ≈20 | ≈20 | ≈ marks a rounded figure, or a size worked out from an older statement by the provider.

Click it to open Sources. ### ≈ marks an estimate A rounded figure, or a size worked out from an older statement, is drawn with ≈. A plan with no published size is listed and never added. ### Subscriptions only Fuel counts the plans you signed in with. API keys and endpoints aren't added. ### No 5-hour limit A ChatGPT Pro has no 5-hour limit, so it stays out of the 5-hour figure and is named beside it. ### Good to know - Plan sizes come from Anthropic's and OpenAI's own plan pages and were last checked on 2026-10-23. - Fuel is for Claude and Codex. Other providers' sources keep their own readings. ## Questions **What is fuel?** Fuel counts what your plans have left, on one scale. 100 Claude fuel is a whole Max 20x limit, every 5 hours or every week, so a Pro counts 5 every 5 hours and about 17 a week. 100 Codex fuel is about one ChatGPT Pro's week, so a Plus counts 20 in each. **Why don't the week and 5-hour figures match?** A Max 20x gets 20 times a Pro's 5 hours but only about 6 times its week, so a Pro is a bigger share of the week. Three Pros and one Max 20x have 115 fuel every 5 hours and about 150 a week. The two limits are separate, so their figures never compare. **Why are Claude and Codex counted apart?** Their plans belong to different companies, and a chat runs on its own provider's plans, so the top bar shows the figure for the provider of the chat you're in. **What does ≈ mean?** Either the figure is rounded, or the size behind it was worked out from an older or partial statement because the provider doesn't publish a current one. A Pro's week is 16.67 fuel, so it reads ≈17. The weekly sizes of Claude's Max plans are estimates. A plan with no usable figure is listed and never added. **Do API keys count toward fuel?** No. Fuel counts the subscriptions you signed in with. API keys and your own endpoints are not added. ## More features [All features](https://shuriken.sh/features) - [Source switching: One account runs dry, the next takes over](https://shuriken.sh/features/source-switching) - [Session limits: Always running, on every account](https://shuriken.sh/features/session-clock) ## Bring your agents.
