DeepSeek launches V4.1-Flash: smallest model in new architecture family with native vision
joecole · x · 2026-09-10
DeepSeek officially unveiled DeepSeek-V4.1-Flash, billed as smarter, faster, and more efficient:
- The smallest model in its new architecture family, with native visual understanding
- Designed for higher capability, faster inference, higher throughput, and scaling to larger models
The post also quotes bertgodel's take that the "age of research" for post-training ended months ago — that engineering the data and environment pipeline now yields substantially higher marginal returns than algorithmic novelty in post-training.
