DeepSeek-V4.1-Flash is built on YOCO, a decoder-decoder architecture cutting GPU memory and prefill latency
donglixp · x · 2026-09-11
Hugging Face's Niels Rogge explains YOCO (You Only Cascade Once): it powers the newly released DeepSeek-V4.1-Flash.
- YOCO is not an encoder-decoder but a decoder-decoder architecture.
- Its goal is reducing GPU memory usage and prefill latency.
- You can ask the paper questions directly on Papers with Code.
