Byte Tokens并非专门来表示汉字的,它们也用来表示其他UTF-8 token,因此Byte Tokens很难学习汉字的语义。 解决办法是:用额外的中文token来扩展LLaMA tokenizer的词表,并为新的tokenizer适配模型。 BPE BPE是使用最广泛的tokenizer,而且是GPT使用的方法,因此最重要。 训练(词表的确定) 方法描述: 确定语料库中全词的...
we prevent BPE from merging across character categories for any byte sequence. We add an exception for spaces which significantly improves the compression efficiency while adding only minimal fragmentation of words across multiple vocab tokens. ...

• 根据生产力 LLM 和陪伴 LLM 的使用对比,ChatGPT 的单轮交互文本量比 Character 更多,用户会输入更长的知识信息:平均用户输入 200 tokens (150 words),GPT 输出 300 tokens (225 words)。 3. 单次交互成本: • 其他生产力 LLM 在以上方案中,闭源方案中 ChatGPT-3.5 是最便宜的;开源方案中 Anyscale ...

Craft your context tokens Rethink, and challenge your assumptions about how much context you actually need to send to the agent. Be like Michaelangelo, do not build up your context sculpture—chisel away the superfluous material until the sculpture is revealed. RAG is a popular way to collate ...
