A 262K token context means the model can process approximately 200,000 Chinese characters in a single conversation, at the cost of the KV cache occupying large amounts of VRAM and memory as the context grows.

UnverifiedLarge language models have an inherent context window limitation, with the number of tokens that can be processed in a single pass typically ranging from tens of thousands to hundreds of thousands of tokens.74% similarUnverifiedThe conversational memory mechanism is essentially concatenating historical messages into the context window, so context length limits (e.g., 4K, 8K, 128K tokens) become a key constraint.71% similarUnverifiedThe weight file of a 7-billion-parameter language model occupies approximately 14 GB of storage, while training data often reaches several TB or even tens of TB.71% similarUnverifiedKV Cache stores the Key and Value matrices of all previous tokens during the Decode phase, grows with conversation turns and context window size, and can occupy anywhere from a few GB to tens of GB of memory in long-text scenarios70% similarUnverifiedStoring a 1-million-token conversation now requires less than 1 GB of memory, whereas larger previous-generation models required at least 3.7 GB.70% similar
