FLUX 3 Max API Pricing: $0.0608 per Second at 720p

FLUX 3 Max on HiAPI is billed by the second of output: $0.0608 per second at 720p and $0.1036 at 1080p. A five-second 720p clip comes to $0.304, a five-second 1080p clip to $0.518, and resolution is the only thing that moves the rate. Native audio adds nothing to the bill.

How much does FLUX 3 Max cost per second?

Resolution	Per second	5-second clip	Credits per 5s
720p	$0.0608	$0.304	608
1080p	$0.1036	$0.518	1,036

Billing is one formula: per-second rate × duration, where duration is a whole number from 5 to 20. Resolution sets the rate, generate_audio is free either way, and failed tasks are not charged. The model page shows the same figures in credits, at 2,000 credits = $1.

What a first test costs: $10 buys about 32 five-second clips at 720p, or about 16 ten-second clips; the same $10 covers about 19 five-second clips at 1080p. That is enough to take one prompt through several rounds of camera and pacing changes. Run your first clip on the model page →

What does a month of clips cost?

At 720p with five-second clips:

Clips per month	Cost
100	$30.40
1,000	$304
10,000	$3,040

Three clips a day is 90 a month, under $30.40. A feed of 1,000 clips runs about $304. For 1080p, multiply each clip's duration by $0.1036.

720p or 1080p?

• Find the direction at 720p. Lock camera movement, pacing and transitions at $0.304 a clip, and iterate as many rounds as you need.
• Move finals to 1080p. At $0.518 for five seconds, it is the tier for hero videos, large screens and footage that will be cropped.
• Use the full duration. duration goes up to 20 seconds, so a long take can be generated in one pass instead of several segments stitched together.
• Match the aspect ratio to the placement. aspect_ratio supports auto, 21:9, 2:1, 16:9, 4:3, 1:1, 3:4 and 9:16, all at the same price per resolution. Vertical feeds take 9:16.
• Leave audio on. generate_audio defaults to true, so ambience, dialogue and effects arrive with the picture at no extra cost. Turn it off when you plan to score the clip later.
• Submit each task once. Poll with the returned taskId; a repeated POST creates a new task and is billed again.

The prompt below is written for five seconds, 16:9 and 720p: one continuous morning shot in a bakery.

A single continuous five-second shot inside a small bakery at dawn. A baker in a flour-dusted apron slides a tray of croissants into a deck oven and closes the door with a soft push. Warm oven light spills across stainless steel, steam curls upward, and the camera slowly pushes in from a medium shot to a close-up on the golden crust. Shallow depth of field, gentle handheld micro-movement, warm amber palette, realistic textures. Ambient sound: the oven door clunk, a low kitchen hum, faint morning street noise outside.

Generate with this prompt →, then set the resolution to 720p, the aspect ratio to 16:9 and the duration to 5 seconds.

FAQ

What can I do with the 200 credits? They are worth about $0.10, less than a five-second 720p clip at $0.304. Top up and the model page is ready to generate; the balance and the charge for each clip are visible in the dashboard.

Is it cheaper with the audio off? No. generate_audio only decides whether the clip has sound; the rate is set by resolution and duration.

Am I charged for failed generations? No. Failed tasks are not billed.

Can I start at 720p and switch to 1080p later? Yes. Every task is billed on its own, and the prompt, aspect ratio and duration carry over; change resolution only.
