Offline RL is a mess: unclear goals, tangled code, and sneaky online tuning A team from University of Oxford fixs it with: Unifloral — one clean framework, shared hyperparams
Result? New SOTA algorithms: TD3-AWR & MoBRAC.

Reasoning models achieve top performance without extended thinking
By
–
So apparently… Reasoning models can be effective without thinking! This flips the table on assumptions that long, detailed chains of thought are always necessary. Turns out, with the right training methods, even concise responses can deliver top-tier performance.

Modern Neural Networks Rely on Dense Matrix Operations Like Cray Computers
By
–
All of the modern NN work that is accomplishing things is with dense matrix ops — 1 mat mul forward and 2 back. There are plenty of things Cray vector computers weren’t good at, but dense matmuls was their strong point, and no PC could touch them for nearly two decades. The XMP

Use chain of thought for research and analysis tasks
By
–
7/ Use "chain of thought" for research or analysis tasks. Ask GPT-4.1 to:
– Break down what you're asking
– Consider key factors
– Analyze options
– Reach a conclusion This structure produces dramatically better results than just asking for an answer.
