Reinforcement learning systems can fail when their reward functions are incorrectly specified, causing algorithms to behave in unintended ways. The article explores this failure mode through examples of how misaligned objectives lead to counterintuitive breakdowns in RL systems. Understanding these misspecification failures becomes critical for developing more robust reward design practices in deployed systems.

The biggest throughline today wasn’t model architecture—it was the plumbing. DeepSeek open-sourced DeepInfer, the inference framework behind its production AI services, and backed it with numbers: one cluster serving 155 trillion tokens per day, plus off-peak pricing at $38 per GPU hour. DeepInfer now ships under an Apache 2.0 license on GitHub with support for DeepSeek-V4.1-Flash, while some performance-critical components remain tied to internal infrastructure and non-Nvidia determinism. In other words, the team is sharing the parts that get customers running, and keeping the bits that keep their edges sharp.
