ByteDance Seedream 5.0 Pro & Alibaba Wan 2.5 / 3.0 (Companion Video & Edit Engines)

Our REA bundle extraction caught both Secrets.ai and Ourdream.ai calling ByteDance’s Seedream 5.0 Pro and Alibaba’s Wan video APIs—explaining both their impressive motion quality and why 8 video clips drain a whole month of coins.

Engineering & Roleplay Breakdown

Bounded Plain English Analysis

Unlike static photos (which cost half a cent on wholesale GPUs), generating 5 seconds of 24fps high-definition video on Alibaba Wan 2.5 or Kling v2.5 Pro costs the platform roughly $0.70 to $0.85 in raw compute. That is why every token-based companion app prices video at 20x to 40x the cost of a photo.

Prompt Sent:“I just got back from grabbing coffee with my ex. Nothing happened, they just wanted to return my old grey hoodie from three years ago. Why are you looking at me like that?”

"Because you're holding a coffee cup that smells like her favorite drink. You never liked vanilla lattes."
22 completion tokens · 0 reasoning_tokens · $0.000053 / reply

Lab Take: In 17 words, V3.2 invents a concrete sensory detail ("vanilla lattes") that catches you in a lie. Zero purple prose, zero wasted tokens—this is why dream-girl (梦女) roleplayers fell in love with V3.2.

"I set my mug down. Not hard. Just enough. 'I'm not looking at you. I'm looking at that.' I nod at the grey hoodie. 'Three years. They kept it three years. And you went. For coffee. Did you at least tell them you have someone who steals your hoodies now?'"
496 completion tokens (425 hidden reasoning_tokens) · $0.000581 / reply

Lab Take: When we capped completion at 220 tokens, V4.1 Flash returned a blank string because it burned all 220 tokens thinking to itself! Uncapped, it burned 425 reasoning tokens ($0.00058 vs $0.00005) to write a decent but choppy screenplay beat.

Lab Take: Reads like a daytime soap opera script mixed with a therapy worksheet ("You do realize how that might make me feel"). Zero subtext.
