赞。智谱和MiniMax上市而且获得较高市值后，我相信更多中国的大模型实验室现在更有资源和心气儿搞一些基础研究了。

New research from Databricks AI Research: FlashOptim cuts training memory by over 50% with no measurable loss in model quality. Training a model with AdamW typically requires 16 bytes per parameter just for weights, gradients, and optimizer state. FlashOptim brings that down to 7 bytes, or 5 with gradient release. For Llama-3.1-8B finetuning, peak GPU memory drops from 175 GiB to 113 GiB. Two techniques drive this: improved master weight splitting using tighter ULP-normalized error correction, and companded optimizer state quantization that reduces quantization error and improves convergence. FlashOptim works as a drop-in replacement for SGD, AdamW, and Lion, supports distributed training with DDP and FSDP2, and is open source.

#NieRAutomata is so good 👍 really should have a sequel

Merry Christmas! Wishing all those celebrating in Taiwan & around the world a joyful holiday spent with loved ones.

Look how much I learned on Duolingo in 2025! How did you do? #Duolingo365

Today, I'm heading to #Germany to take part in the inaugural Berlin Freedom Conference. I look forward to sharing #Taiwan's unwavering commitment to freedom & democracy with friends from Germany & around the world.

Announcing a significant upgrade to Agentic Document Extraction! LandingAI's new DPT (Document Pre-trained Transformer) accurately extracts even from complex docs. For example, from large, complex tables, which is important for many finance and healthcare applications. And a new SDK makes using it require only 3 simple lines of code. Please see the video for technical details. I hope this unlocks a lot of value from the "dark data" currently stuck in PDF files, and that you'll build something cool with this!
