UnverifiedTokens 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.74% similarUnverified在基于 LLM 的 AI 编程助手中，Token 是计算成本的基本单位，输入和输出文本都会被切分为 Token 计费71% similarUnverifiedThe cost of each large language model call consists of two parts: input tokens (Prompt) and output tokens (Completion).70% similarUnverifiedIn large language model inference, the actual hardware cost of output tokens is far higher than that of input tokens, because the decoding phase is a memory-bandwidth-limited sequential process.69% similarUnverifiedA token is the basic unit of billing for large models and is essentially the smallest semantic segment after text is split.68% similar
