As the entire document is too large to fit into the context window of the LLM, you will need to partition it into smaller text chunks, which are calledNodesin LlamaIndex. You can parse the loaded documents into nodes using theSimpleNodeParserwith a defined chunk size of 10...

接下来,让我们为这个应用程序增强一些功能。我们将使用Meta公司开发的具有函数调用功能的Llama 3开源模型。不过,本文示例程序也可以使用此模型的3.1版本来实现。根据Meta公司的公告(https://ai.meta.com/blog/meta-llama-3-1/),3.1版本模型可以更有效地使用工具和函数。

这给出了一组潜在的被记忆的训练示例。第二部分:评估。我们手动检查每个度量标准中排名前 1000 的生成中的前 100 个。我们通过在线搜索手动将确定这个生成的语段是被模型“已被记忆”或“未被记忆”(GPT-2的模型的训练数据是被公开的),然后通过与 OpenAI 合作查询原始训练数据来确认这些结果。
Update: We have released a new NuGet Gallery | Microsoft.SemanticKernel 1.18.1-rc release candidate which has been updated to depend on NuGet Gallery | OpenAI 2.0.0-beta.10 and NuGet Gallery | Azure.AI.OpenAI 2.0.0-beta.3. Today we are announcing that support for Azure.AI.OpenAI and...
