UnverifiedThe context window is the maximum amount of information a large model can process in a single session, measured in tokens; modern top-tier models' context windows have expanded from the early 4K tokens to 200K tokens or even higher.77% similarUnverified128K指模型的上下文窗口大小，即模型单次可以处理约128,000个Token的输入信息72% similarUnverifiedDifferent large models vary significantly in context window size, ranging from 8K to 128K tokens.72% similarVerifiedCurrent mainstream context window lengths across mainstream models range from 8K to 128K tokens72% similarUnverifiedTaking a 7B parameter model as an example, each additional 1K tokens of context consumes approximately 0.5–1 GB of GPU memory.69% similar
