CAVEATS
What the source record does not assume.
01
Official BFL API endpoint is POST /v1/flux-2-klein-9b. The model's weights are available with license terms; open weights do NOT imply unrestricted commercial usage.
02
BFL API published price: $0.015 for the first OUTPUT megapixel, +$0.002 for each additional output MP, +$0.002 per reference-image input MP. Displayed $0.015 is a STARTING first-MP rate.
03
Image pixels are rounded to billed megapixels; reference images and resolution can increase per-result charges. 4K and multi-image workflows require checking configuration caps.
04
Useful for low-latency imagery and on-premise experimentation; quality comparisons must use real prompts.
