@Mononofu@JensenHuang This is a false equivalence. Everyone has the right to keep their code private. The problem is when someone tries to stop OTHERS from open sourcing.
We (@lawrence_cjs, @yuyangzhao_, @shanasaimoe@songhan_mit ) from the SANA team just posted our second blog: "Bet Small to Win Big: Efficient 2K Video Generation via Deeper-compression AutoEncoder, Linear Attention and Two-Stage Refiner"!
Huge thanks to @ltx_model and @Lightricks for their powerful higher-compression VAE and refiner! 🙏
In this post, we dive into how we adapted and integrated LTX's refiner into our SANA framework to build an efficient Two-Stage pipeline. We share the technical details of this (non-trivial) integration and analyze why it delivers stunning 2K video generation with virtually no extra latency or computational overhead compared to our 720p baseline. Bet small to win big! 🚀

Happy to see the Canva's magic layer feature launched succesfully! This feature enables you to generate fully editable, layer-wise designs, and I helped making the underlying foundation model 100% faster😁, check out the official product annoucement: https://t.co/EqDuT4elFm
@teortaxesTex Hi, Helios author here, I believe YuanLab is actually a different bunch of people from us haha 😂,Helios is from Peking University and Bytedance, we are not aware of Yuanlab.
Today we are thrilled to annouse our latest work: Helios, the world's first open-source 14B video model that performs minute-scale, high-quality video synthesis at 19.5 FPS(!) on a single H100 GPU (https://t.co/hb4b9Uk4AO). Trailer: https://t.co/Fx90OFfgSV (1/n)
Seedance 2 just dropped as open-source.!.. ok, mostly...
Helios - 14B model for minute-scale vid gen.
- high-quality, fast
-No KV-cache, no quantization, no TinyVAE, just pure architectural efficiency.
- T2V/I2V/V2V ready.

🤯Real-time video generation just got HUGE.
Introducing Helios: A 14B parameter model running at 19.5 FPS on a single H100.
Cheaper, Faster, and Stronger than 1.3B models, generating minute-long videos without the usual tricks (even no quantization).

🎉 Meet Helios, a 14B video generation model that runs at 19.5 FPS on a single NVIDIA H100 GPU. Day-0 support is now live in SGLang!
🎬 Unified T2V / I2V / V2V: all three tasks in one architecture
⚡️ 19.5 FPS on a single H100 — no KV-Cache, no sparse/linear attention tricks needed
📽️ Minute-long video generation: stable, coherent, no Self-Forcing or Error-Banks required
🧠 14B model trainable at image-model batch sizes — no parallelism or sharding infrastructure needed
