The author picks three open-source projects as especially important in modern AI: FlashAttention 2, SGLang, and DeepSeek v3.
- FlashAttention 2 is praised as the most important installment in the FlashAttention line for its balance of correct complexity, practical adaptability, and long-lived performance on new GPUs.
- SGLang is highlighted as a foundational project for serving and inference, with a nod to Mini-SGL as a cleaner alternative that briefly looked poised to take over.
- DeepSeek v3 is framed as the spark that helped trigger the next wave of open-weight momentum, making openness itself more durable in the ecosystem.
