什么是 RLHF？

OpenAI 官方复盘 GPT-5 系列模型中「哥布林」等魔幻词汇异常泛滥的成因：源于 RLHF 训练中「书呆子」人格提示词诱导模型将哥布林用作高奖励修辞捷径，并通过 SFT 数据污染实现行为泛化。

Rohin Shah argues that while AGI safety risks deserve attention, catastrophic misalignment is not inevitable, and prosaic alignment techniques are likely sufficient to prevent worst-case outcomes, especially since current concerns like deception are not default behaviors in real training.

Cursor leverages sparsity in RL training weights to transmit only deltas, reducing 1TB model sync traffic by 20x for lossless, fast global transfer during active training.

TypeSafe.AI的System One模型Jev通过结构化输出和RLCD训练法，在决策类任务中优于传统LLM，尤其适合意图分类场景。

AI研究者认为递归自我改进（RSI）的核心挑战是目标定义与泛化能力，而非单纯算力提升，自动化研究可能直接等同于人工通用智能（ASI）。

InstructGPT is a system fine-tuned from GPT-3 that demonstrates how human feedback can transform a capable language model into a far more useful and aligned assistant.

Even assuming AGI requires a new paradigm, applying Lindy's Law suggests it may emerge within 3 to 5 years, so current AI development risks shouldn't be underestimated.

In the AI era, Markdown dominates due to high token efficiency and model preference, but HTML is emerging as the superior output format for interactivity and visual fidelity.

StepFun launches StepAudio 2.5 real-time voice model with paralinguistic perception and personalized interaction capabilities.
