The AI cloud service fal developed MiniMax H3 Max, which generates 15-second videos in about 13 seconds while maintaining quality. It offers 5-second videos free up to five times daily, with Japanese prompt support, and costs $0.08 per second at 768p, a 50% off sale until September 1.","whyItMatters":"fal's MiniMax H3 Max undercuts the official Hailuo.ai generation time by a factor of roughly 36 and beats Seedance 2.0 on price per second, making high-speed video AI far more accessible.","webCardHtml":"\u003cp\u003eThe open-weight release of MiniMax H3 on August 3 triggered a wave of community and official updates. The most striking is MiniMax H3 Max from fal, which turns out 15-second clips in about 13 seconds. On fal\u0026#39;s service, typing a Japanese prompt yields a 5-second video in roughly 3.3 seconds. The same generation on Hailuo.ai, MiniMax\u0026#39;s official service, takes about two minutes.\u003c/p\u003e\u003cp\u003efal achieved the speedup by post-training H3 specifically for H3 Max, reducing inference steps while avoiding quality loss. The service lists 768p at $0.08 per second, with 15 seconds at $1.20, half off until September 1. That compares with Seedance 2.0\u0026#39;s $0.30 per second for audio-included generation. According to an AI performance comparison site, H3 Max even surpassed Seedance 2.0 in the image-to-video with audio category.\u003c/p\u003e","blueskyPost":"MiniMax H3 Max's 13-second generation time for a 15-second clip reframes the bottleneck from speed to cost, with the $0.08 per second rate at 768p becoming the real gate for daily use.","twitterPost":"MiniMax H3 Max makes 15-second videos in 13 seconds, but the $0.08 per second price is the real constraint for casual creators.","threadsPost":"MiniMax H3 Max generates a 15-second clip in 13 seconds, which makes speed nearly a non-issue. The trade-off is cost: $0.08 per second at 768p, even with the 50% discount running until September 1. Free 5-second clips, capped at five per day, signal that the free tier is a sampler, not a workflow.","newsletterBlurb":"fal's MiniMax H3 Max generates 15-second videos in about 13 seconds, with 5-second clips free up to five times a day and Japanese prompt support.
