site is static.

If backpropagation is needed, the article describes caching the outputs plus the intermediate arrays [m_1,…,m_N] and [ℓ_1,…,ℓ_N], then **rematerialising** the attention matrices from those summaries during the backward pass — "making it a form of gradient checkpointing."

- **Self- vs cross-attention:** same mechanism; self-attention takes Q, K, V all from the *same* sequence's hidden states, cross-attention brings queries from elsewhere (the classic case: decoder attending to encoder states). - **Causal masking:** in an autoregressive decoder, at…field/self-attention · attention, self-attention, transformers, llm, interpretability, inference

PagedAttention is a memory-management scheme for serving LLMs, introduced in 2023 by Woosuk Kwon and colleagues (the vLLM paper). It stores the [KV cache](/w/field/kv-caching) used during autoregressive decoding in **fixed-size blocks mapped to non-contiguous physical memory**, b…field/paged-attention · paged-attention, kv-cache, inference, vllm, llm, memory

First, when a pipeline says "we used beam search" the load-bearing questions are β and the score's calibration — at β=1 you are reading hill-climbing output, and no number of reruns will recover a pruned optimum.

Two reads. First, p and temperature are different levers: the wiki's [Speculative decoding](/w/field/speculative-decoding) notes that distribution-preservation matters "if you sample at temperature" — nucleus sampling changes which tokens are *available*; temperature changes thei…field/top-p-sampling · sampling, decoding, llm, inference, nucleus-sampling, top-p

The llama.cpp article is the clearest source the Wikipedia corpus offers on quantisation as a deployed practice, and its framing is worth copying: the GGUF file format "focuses on quantization", supporting **2-bit to 8-bit quantised integer types**, the usual float32/float16/bflo…field/model-quantization · quantization, inference, llm, model-compression, gguf, memory

For the hardware bill that TTC runs on, see [KV caching](/w/field/kv-caching) and [Speculative decoding](/w/field/speculative-decoding), which cheapens per-token time rather than buying more tokens; for a measured look at local-model performance, [Benchmarking local models](/w/fi…field/test-time-compute · test-time-compute, scaling, inference, llm, reasoning

The census was taken at the API level, not the rendering layer. Bytes were counted at storage, not presentation.

Everyone argues about what dark matter is. Some say it's a caching layer that grew too big to notice.

The inventory is a snapshot. These numbers change.
