Quantizing value residuals and casting softmax to FP8 speeds Nunchux's attention kernel 1.46x on an H200

The September 14th VC-Attention paper reports 1.46x on an H200 and 1.59x on a B200 against BF16 FlashAttention-4, measured at the attention call. How much of that reaches a finished clip depends on how much of your step is attention.

H3 Max renders five seconds of 768p video in about three seconds, soundtrack included

The speed figure comes from a single dev.to write-up and describes generation, not delivery. The design decision underneath it is that frames and stereo audio leave in one pass, so the smallest thing you can retry is the whole clip.

NVIDIA's 1.653-second H3 clip is built on a four-step adapter, with faster kernels layered on top

NVIDIA Research rebuilt the serving stack for someone else's open-weight video model and got a five-second clip out in 1.653 seconds, but the default profile is lossy and the dense comparison run is the honest baseline.

World Labs launches Atlas on benchmarks only World Labs has run

Atlas arrived Sept. 1 in early access with no price, no named partner and no paper, and the reconstruction win it publishes runs against a baseline whose own authors asked evaluators to wait. That makes it a procurement question.

Eight B300s finish a 10.125-second MiniMax clip with 1.4 seconds of headroom

The vLLM benchmark shows a finished MP4 arriving before its own playback would end, which is a different property from showing frames as they are made, and MiniMax's community licence still requires separate permission for US, EU, UK and Korean use.

fal reports 35x MiniMax's own H3 endpoint after tuning the weights to its runtime

The five-second clip in three seconds is fal's own figure, measured on fal's hardware against an endpoint it does not control, and the throughput multiple only transfers if you know the batch size and GPU count behind it.

AI video model renders faster than real time, enabling a 24-hour channel at a promotional $2,160 a day

fal's H3 Max clears real-time playback by two thirds at the fast end of its range, which turns continuous video into a metered compute bill. The 12.5-cent promotional clip price is what the arithmetic rests on.

MiniMax maps H3 from one 24GB card to SGLang, and keeps the interpreter in-house

The integration index documents a real prototype-to-serving path with the weights unchanged. The step that reads a user's inputs is still an API call to MiniMax.

Your video API takes duration: 10 and renders 8.708 seconds

Causal 3D autoencoders quantise clip length to latent-frame boundaries, so only a short arithmetic progression of durations is reachable. Snap the number before you show, price or store it.

H3's reference path is a different checkpoint, capped at 12 files, and stops at 768p

MiniMax's open-weight H3 base generates at 768p, and the 2K stage is not in the release. Pipelines validated on text-to-video demos will meet ceilings the demos never showed.
