01 · Overview
What is FLUX 2 Flex?
FLUX 2 Flex is the flexible member of the FLUX.2 family: the same generation quality as its siblings with step and guidance controls under the hood, tuned for creators who want strong results without the flagship price.
Four tiers priced by megapixels: 1MP at 7 credits, 2MP at 14, 3MP at 20, 4MP at 27. Edits are a flat 14 credits at every tier and take up to eight references. New accounts start with 20 free credits: two 1MP images and change.
Specs & capabilities
| Inputs | Text to image · Image editing · Multi-reference (up to 8 in the studio) |
| Resolution | 1MP, 2MP, 3MP or 4MP tiers |
| Aspect ratios | 7 ratios in the studio, from 1:1 square to 16:9 wide |

| Pricing shape | Per-tier upstream: 1MP $0.04, 2MP $0.08, 3MP $0.12, 4MP $0.16 — priced here at 7, 14, 20 and 27 credits. Edits bill the 2MP rate at every tier: flat 14 credits. |
Good to know: edits always bill at the 2MP rate ($0.08 upstream), whatever tier you pick — so the edit price is a flat 14 credits and edit outputs land around 1MP. The 1MP tier is the cheapest FLUX.2 generation on Pizyn after Pro's flat 5.

Prompt guide
- Flex is the value tier: 1MP at 7 credits is the cheapest FLUX.2 generation outside Pro's flat 5 — start here by default.
- Draft at 1MP: explore compositions cheaply, then re-render the winner at 3MP or 4MP.
- Edits are tier-free: the flat 14-credit edit price means you never have to think about tiers in edit mode.
- Max for the hard briefs: FLUX 2 Max (from 10 credits) spends more compute on difficult compositions — reach for it when Flex fumbles.
