a16z 访谈 fal：重建 MiniMax 开源视频模型 H3，速度提升 35 倍
a16z 发布与 fal 团队 Gorkem Yurtseven、Batuhan Taskaya 的对话，介绍其重建 MiniMax 开源视频模型 H3 的工作：精简生成步骤、重写各阶段代码，将 GPU 利用率从通常的 30–40% 提升至理论峰值的 70–80%，实现 35 倍加速且无质量损失，5 秒视频可在 1.5 秒内生成。访谈还提到好莱坞已成为 fal 增长最快的客户群，镜头延展、运镜与灯光调整等编辑成功率达 80–90%，团队正追求 99.9% 可靠性。上述数据来自厂商与投资方自述，未经独立验证。

.@fal's Gorkem Yurtseven and Batuhan Taskaya on making an open source video model 35x faster, and what Hollywood wanted after they built it:
Last month, MiniMax released H3, an open source video model. fal rebuilt it - they cut down the steps the model takes to make a video, rewrote the code under each stage, and got the GPUs to 70-80% of their theoretical ceiling instead of their usual 30-40%. No quality loss.
Video now generates faster than you can film it. The models have gotten so cheap and fast that end users aren't even asking for improvements in either category anymore. The gap has moved to quality, or how closely the model follows the prompt.
Hollywood wasn't a customer a year ago and is now fal's fastest growing segment. Studios love it for the little things - extending a shot, moving the camera, changing the lighting. Those edits land 80-90% of the time. fal is chasing 99.9%.
In this conversation with a16z's Jennifer Li:
00:00 Intro
01:45 The first open model worth rebuilding
03:45 The industry ran out of compute in April
06:25 35x faster without losing quality
11:05 5s of video generated in 1.5s
14:25 The weekend fal dropped everything
16:15 3 viral projects nobody planned
18:20 Teaching a video model to remember
20:25 An hour of video that's consistent
23:30 2x the usage of other models in 3 weeks
26:35 The case for giving video away for free
29:00 Blender sketch in, finished shot out
30:40 Chasing 99.9% reliability
34:15 Hollywood, fal's fastest-growing customer
36:50 Why studios wouldn't touch it until now
