context window,即LLM所允许的“输入+输出”(Prompt+Completion)最大tokens长度限制。 常见的开源模型,这一数值通常为2k、4k;常见的闭源模型,往往能够达到更大的数值,如GPT-3.5-turbo支持16k,GPT-4支持128k,而Claude 2.1则支持200k。尽管如此,我们依然可以隐隐感觉到,提升context window的大小,在目前的技术范式下(以...
In contrast, LLaMA models that are extended via direct fine-tuning only saw a minimal increase of the effective context window size kmax from 2048 to 2560, even after fine-tuning for more than 10000 steps, with no clear indication of an acceleration in the increase of window size. 相比之下...
2.上下文窗口扩展(Context Window Extension):该方法实打实地去扩大LLM的上下文窗口长度,也就是序列长度。因为Attention的计算量和内存需求都随着序列长度增加而成平方增长,所以增加序列长度很难,一些实现方法包括:训练时用FlashAttention等工程优化,以打破内存墙的限制,或者一些approximate attention方法,比如Longformer这种Windo...
Longer prompts, however, can result in 1) increased API response latency, 2) exceeded context window limits, 3) loss of contextual information, 4) expensive API bills, and 5) performance issues such as “lost in the middle.” Inspired by the concept of “LLMs as Compressors,” we ...
NTK-Aware Scaled RoPE allows LLaMA models to have extended (8k+) context size without any fine-tuning and minimal perplexity degradation:https://www.reddit.com/r/LocalLLaMA/comments/14lz7j5/ntkaware_scaled_rope_allows_llama_models_to_have/?rdt=44479 EXTENDING CONTEXT WINDOW OF LARGE LANGUAGE MO...
benchmarkincludes several complex multi-hop or multi-needle tasks, effectively reflecting the actual context window size of LLMs. As shown in Table 1, our method effectively preserves the actual context window processing capability of LLMs and even slightlyextends the actual...

Prepare community summaries. Community summaries are randomly shuffled and divided into chunks of pre-specified token size. This ensures relevant information is distributed across chunks, rather than concentrated (and potentially lost) in a single context window. ...
Large Language Models (LLMs) operate with a defined limit on the number of tokens they can process at once, referred to as thecontext window. Exceeding this limit can have significant cost and performance implications. Therefore, it is essential to manage the size of the input sent to the ...
