Flux ACUs
Flux ACUs
Understand and manage your Flux ACUs to optimize your use.

Overview
An ACU (Agent Compute Unit) is the unit of measurement for AI usage in Flux. Every time you use an AI-powered feature in Flux, a certain number of ACUs are consumed depending on the complexity of the request. ACUs are designed to help you budget and pay for your Flux AI usage, with a system that correlates ACU consumption to Flux usage.
:::info Info Users and organizations on any of the free or student plans cannot purchase additional ACUs besides the included balance. To purchase additional ACUs, you will need to upgrade to any of the paid individual or organization plans. :::
How do ACUs work?
Every time you interact with Flux through the Chat tab in the right sidebar, you will be using Flux ACUs. The number of ACUs used on any interaction will depend on the complexity of the prompt and the project. Due to the nature of AI systems, it is not possible to know how many ACUs a prompt will require beforehand.

How do ACUs get used?
These are the rules that determine whose Flux ACUs will be consumed when working in a project that is owned by someone else:
- If the project is organization-owned and the commenting user is a member of that organization, ACUs will be taken from the organization.
- If the project is organization-owned and the commenting user is not a member of that organization, ACUs will be taken from the user creating the comment.
- If the project is owned by a user and not an organization, ACUs are always taken from the commenting user's balance.
Types of ACUs
Included ACUs
- We want every user to try Flux, so every plan includes free Flux ACUs.
- Included ACUs are renewed the first day of every month.
- Included ACUs don't have rollover, meaning unused ACUs from one month do not get added to the following month's balance.
Paid ACUs
- Billed at the end of each month based on usage. Read the section below to learn how to manage your ACUs.
- Users can set a monthly maximum budget.
- Budget and ACU usage are displayed transparently to the account owner.
Managing Your ACUs
All ACUs are used within the context of the project where Flux is being referred to. Meaning, if the project is owned by an organization, they are taken from the organization's ACUs. If the project is owned by a user, they will be taken from the user that owns the project. Cross-use of ACUs is not allowed. A user cannot use their ACUs on organization-owned projects and vice-versa.
ACUs are managed slightly differently between users and organizations, see below for managing your ACUs depending on what user type you are.

Purchasing Additional ACUs
- ACUs cannot be purchased in advance. If you need more ACUs, simply increase your monthly spending limit.

FAQ
What happens if I don't like Flux's answer or if it doesn't give me something useful. Are the ACUs still used up?
Flux has all the relevant context of your project and is optimized to provide the most accurate responses possible. You can also follow these tips for better prompting to get the most out of Flux.
But due to the nature of AI systems, the accuracy of answers can't be predicted. Flux ACUs will be consumed independently of the answer it provided.
