Open weights, and the license is built for small teams
Lightricks dropped LTX-2.5 on Aug 11 with weights on Hugging Face, free to use commercially for any organization under $10M in annual revenue; only larger companies negotiate a license. The LTX family has now passed 33M downloads.
It runs on a 16GB RTX card, ComfyUI on day one
The open weights self-host 720p video on as little as 16GB of VRAM, with a distilled build tuned for RTX GPUs and a native ComfyUI integration shipping the same day. A weekend project: image-to-video b-roll generated entirely on your own machine, no API bill.
Synchronized audio, Auto Duration, and 4K
Native audio ships at every resolution, no separate model. The Fast variant reaches 4K and 20-second clips, and 'Auto Duration' reads your prompt to pick the clip length. A 10-second 720p clip renders in 6.8 seconds on dual GB200s, with a claimed 67% win rate in blind preference tests.
The API math starts at $0.09 a second
Don't want to host it? fal runs LTX-2.5 from $0.09/sec at 720p up to $0.30/sec at 4K on the Fast tier, while Pro image-to-video is $0.12/sec at 720p. Native audio is bundled at every tier, so there's no second bill for the soundtrack.
Elsewhere: Sakana's Namazu lands on OpenRouter
Sakana AI's Japanese-tuned model, built on Moonshot's Kimi K2.6, is now callable through OpenRouter at roughly $0.95 per million tokens, though it stays blocked in the EU. A cheap, specialized option if you ship for Japanese users.
