Riverflow 2.0 Fast: AI Image Editor Online
Bottom line
Riverflow's drafting tier: the same 10 aspect ratios as Pro, capped at 2K, up to 10 reference images, 10cr. Open the Image Edit tool, select Riverflow 2.0 Fast, upload your image, and the exact credit cost appears before the edit runs.
Riverflow 2.0 Fast is the quicker, cheaper tier of Sourceful's Riverflow image editor — a specialist editing model rather than a general text-to-image generator, taking up to ten reference images per job across ten aspect ratios. That list includes the 5:4 and 4:5 near-square, photo-print proportions that most editors skip in favor of standard social ratios, alongside the usual square, portrait, landscape, and ultrawide options.
Fast trades resolution for speed and cost against its Pro sibling: output caps at 1K or 2K, where Riverflow 2.0 Pro adds a 4K tier. For iterating on wording, references, and framing before committing to a final high-resolution pass — or for jobs that are headed to web and social where 2K is the final stop anyway — Fast covers the work end to end. Prompts run up to 5,000 characters.
VdoBloom prices it at 10 credits per run regardless of resolution, rates it 3.7, and applies the MODERATE content badge — standard filtering.
What it costs on VdoBloom
Riverflow 2.0 Fast is a flat 10 credits per edit at either 1K or 2K — exactly what a new account's 10 free signup credits cover for one run.
Fast vs Pro — the resolution trade
Both Riverflow 2.0 Fast and Pro share the same 10 aspect ratios and 10-image reference capacity; the only functional difference is that Pro adds a 4K output tier (at a 27-credit price, versus 18 credits for Pro's own 1K/2K and 10 credits for Fast). Draft and iterate on Fast, and reach for Pro specifically when a deliverable needs 4K.
Common problems and how to avoid them
Riverflow's 5,000-character prompt ceiling is generous, but a request with unclear or conflicting instructions across multiple reference images will produce inconsistent results the same way it does on any multi-image editor — keeping the instruction specific about what each reference contributes tends to help. VdoBloom shows the 10-credit cost before you run the job and refunds automatically if it fails.
What creators use Riverflow 2.0 Fast for
- Iterating on edit prompts and reference combinations at 1K before committing to a high-resolution final pass.
- 2K social-format delivery in 9:16, 1:1, or 16:9 where a finishing pass on Pro isn't needed.
- Photo-print-proportioned edits at 4:5 or 5:4 for physical output at a lower cost than Pro.

Is Riverflow 2.0 Fast censored?
It carries VdoBloom's MODERATE badge — standard content filtering, the same tier as Riverflow 2.0 Pro.
How many reference images can Riverflow 2.0 Fast take?
Up to 10 per job, the same capacity as Riverflow 2.0 Pro.
Riverflow 2.0 Fast vs Riverflow 2.0 Pro — what's the actual difference?
Resolution ceiling. Fast tops out at 2K for a flat 10 credits; Pro adds a 4K tier that costs 27 credits (1K/2K on Pro stay at 18 credits). Both share the identical 10 aspect ratios and 10-image reference capacity. A common workflow is iterating on Fast, then re-running the finished prompt on Pro only when the deliverable needs 4K.
Riverflow 2.0 Fast vs Flux 2 Pro I2I — which multi-image editor is cheaper?
Riverflow 2.0 Fast takes up to 10 images across 10 aspect ratios for 10 credits (1K/2K). Flux 2 Pro I2I takes up to 8 images across 7 ratios plus an auto mode, with 1K/2K output, for 12 credits. Riverflow Fast is slightly cheaper and covers one more image and two more ratios (including the 5:4/4:5 print formats Flux 2 Pro I2I doesn't offer); Flux 2 Pro I2I's auto ratio mode is the feature Riverflow doesn't have.
Which aspect ratios does Riverflow 2.0 Fast support?
Ten: 1:1, 4:3, 3:4, 16:9, 9:16, 3:2, 2:3, 5:4, 4:5, and 21:9 — unusually broad for a speed-focused tier, including the photo-print 5:4 and 4:5 proportions.
Is Riverflow 2.0 Fast's 2K output good enough for final delivery?
For web, social, and screen-based work, 2K generally holds up as a final resolution. If the image needs to go to print or survive an aggressive crop afterward, Riverflow 2.0 Pro's 4K tier is the one built for that headroom.
