UnverifiedEvery large language model has a maximum token limit it can process, and when the content accumulated by a long task approaches that limit the model will forget early content due to degradation of the attention mechanism over excessively long sequences.78% similarVerifiedOnline large language model services charge separately based on the total number of input and output tokens.77% similarUnverifiedThe cost of each large language model call consists of two parts: input tokens (Prompt) and output tokens (Completion).77% similarUnverified大语言模型推理中输出 token 的实际硬件成本远高于输入 token，因解码阶段是内存带宽受限的串行过程77% similarVerifiedTokens are the basis for billing by large models; they are produced by a tokenizer splitting raw text and are the basic unit by which large models process text.77% similar
