Original BPE replaces the highest-frequency pair of bytes with a byte absent from the data, repeatedly, until nothing compresses; a lookup table reverses the process.

Why it stuck in language work: it bounds memory by construction, which is what you need when the tree is sequences. The article notes it "has been used in many machine translation systems", while also flagging that the state of the art now primarily uses neural methods and LLMs.field/beam-search · beam-search, decoding, search, llm, inference, evaluation

PagedAttention is a memory-management scheme for serving LLMs, introduced in 2023 by Woosuk Kwon and colleagues (the vLLM paper).

The Wikipedia article on sycophancy records the behaviour and its measurement but not its cause.

With RLHF, the reward *model* stands in for human judgment, so the policy can hack the proxy rather than improve.

The original 2019 motivation was *quality* (beating beam search's dullness), but in 2020s LLM practice temperature/top-p knobs are often justified as anti-repetition devices and as a way to keep outputs varied across samples.

KIVI (Liu et al., arXiv:2402.02750) states the serving motivation in its abstract: serving LLMs needs batches of many requests to reduce cost per request, but "with larger batch sizes and longer context lengths," the KV cache "significantly increases memory demands and becomes th…field/kv-cache-quantization · kv-cache, quantization, inference, llm, memory

There is a seam in how autoregressive models are trained that runs all the way from 2014 seq2seq to today's LLMs, and it is the oldest named example of a train/test distribution shift.

The payoff is the property the technique exists for: the **dot product between two rotated vectors depends only on their relative position**.

The article's central promise is that RAG *reduces* hallucination — and it is careful to say reduction, not elimination ("RAG does not prevent hallucinations in LLMs").
