Pricing

The following table shows pricing for all FLUX models and their variants:

​
FLUX 3 Models (Video)

FLUX 3 generates video with synchronized audio and uses per-second pricing — cost scales with clip length, resolution (hd or fhd), and whether you run a full render or a fast draft.
Drafts render at hd and cost about a third of a full render, so you can explore variants freely and only pay full price for the shot you keep. See the FLUX 3 overview for length limits and supported aspect ratios.

​
FLUX Tools (Video)

FLUX Video Upscale is priced per output megapixel-second: the megapixels per output frame multiplied by the output duration in seconds. ¹ One megapixel-second is one megapixel (1,048,576 pixels, i.e. 1024 × 1024) of output resolution for one second of output video. Charges are calculated on the delivered output’s actual frame dimensions and duration: megapixels per output frame × output duration in seconds, with fractional values charged pro rata. Example: upscaling a 10-second clip to 1080p (1920 × 1080 = 1.98 megapixels) is 19.8 megapixel-seconds, i.e. $1.48 (Precise) or $2.08 (Creative). ² Charges are based on output only. Input resolution, upscale factor and optional prompts are not charged separately. ³ Rates apply to output at the standard frame rate of 24 frames per second. Where output at a higher frame rate is requested and supported, charges scale proportionally with frame rate (equivalently, the listed rate ÷ 24 per megapixel per frame). Supported input durations, resolutions, upscale factors and frame rates are set out in the documentation. ⁴ Input videos up to 20 seconds. Sources longer than 20 seconds are rejected before processing; they are not truncated, and no charge applies.

​
FLUX.2 Models

FLUX.2 uses megapixel-based pricing — cost scales with output resolution.
Klein pricing explained: The first megapixel costs a flat rate, then each additional MP adds to the total. For example, a 2MP image with Klein 4B costs $0.014 + $0.001 = $0.015.
FLUX.2 pricing varies by output resolution. Use the pricing calculator for exact costs.

​
Fine-tuned Endpoints (Public Beta)

During public beta, fine-tuned FLUX.2 endpoints are billed at the same rate as their base endpoints. For example, a request to flux-2-klein-9b-kv-finetuned costs the same as the equivalent flux-2-klein-9b request at the same resolution.
Pricing for fine-tuned endpoints may change once out of public beta. See the LoRA inference guide for details on how to call these endpoints.

​
FLUX.1 Models (Previous Generation)

​
Batch Pricing

Batch requests multiply the base cost by the number of images
Example: FLUX.2 [pro] batch of 4 images
  • Single image: from $0.03
  • Batch of 4: from $0.12
