Flux.ai pricing, explained: tiers, ACUs, and the real jump

What Flux.ai's Starter and Pro tiers cost, how ACU metering works, and what its trial terms say — every figure cited to Flux's own pages.

Updated 2026-07-09

The tiers

PlanPrice per editorACUs included
Starter$20/mo, or $16/mo billed annually [1]10 ACUs/mo [3]
Pro$142/mo, or $112/mo billed annually — roughly a 7x jump from Starter [2]100 ACUs/mo per editor [2]

Values above are limited to what Flux’s own cited pricing page states.

The table covers Flux’s two entry tiers, not its whole lineup: above Pro, Flux lists a Teams tier at $158 per editor per month and an Enterprise tier [2].

The gap between tiers

Starter is $20 per editor per month [1]; Pro is $142 per editor per month — roughly a 7x jump, with no tier in between [2]. For a three-editor team, that’s the difference between $60/mo on Starter ($48/mo billed annually) [1] and $426/mo on Pro [2] — a gap of $366/mo, or roughly $4,392/yr, for the same three seats. The ratio holds on annual billing too: $16 [1] to $112 [2]per editor per month is the same 7x step. Whatever Pro adds over Starter, there’s no intermediate tier to phase into it gradually.

How ACUs meter AI usage

ACU stands for Agent Compute Unit — the unit Flux uses to meter AI feature usage [3]. The Starter plan includes 10 ACUs per month [3]; Pro includes 100 ACUs per editor per month [2]. Flux’s own documentation is explicit that consumption isn’t predictable in advance: “Due to the nature of AI systems, it’s not possible to know how many ACUs a request will consume beforehand.” [4] That means the 10 ACUs included with Starter are a monthly allotment, not a fixed count of predictable actions.

Trial terms worth reading

Flux’s Main Services Agreement, Section 2.5 (“Free Trial”), states that any data a customer enters and any customizations made during the free trial “will be permanently lost unless Customer purchases a subscription to the same Services as those covered by the trial, purchases applicable upgraded Services, or exports such data, before the end of the trial period.” [5]
