I purchased the plan to get unlimited generation access until March. This sometimes works for all of the models in video generation and I see 0 credits before generation., However, sometimes it doesn't work for some reason and credits get reducted.

This is how Adobe defines it. Unlimited access for standard features allows users to use core generative AI tools such as Generative Fill & Expand, Text to Image, Text to Vector, and Firefly Boards without consuming monthly generative credits. Credits are reserved for Premium Features like video generation, using non-Adobe models, high-resolution outputs exceeding standard quality, and advanced audio/video tasks. Some paid plans offer a temporary "unlimited" video generation bonus for the Firefly Video Model until March 16, 2026, which does not apply to "Partner" video models. More information is available on Adobe Generative Credits Help Page and Adobe Firefly Plans & Pricing Page
