Just got confirmation with my account manager as well as info on byteplus that the price of seedance 2.5 is 50% more than seedance 2.
For a 30 second video it'll be around $7.50 for a 30 second 720p 16:9 video. (lower than I heard)
And 2.5 is actually available now through their Lumina business package(it's like $300/month) right now, or it'll be released via api in 1-2 weeks
