Semantic Chunking Llama Pack

This LlamaPack implements the semantic chunking algorithm first proposed by Greg Kamradt in his Five Levels of Text Splitting tutorial.

How it works:

• Split text into sentences.
• For each sentence, generate an embedding.
• Measure cosine distance between each pair of consecutive sentences.
• Get the 95% percentile cosine distance, set that as the threshold.
• Create a new chunk if the cosine distance of a sentence compared to prev. exceeds that threshold.

CLI Usage

You can download llamapacks directly using llamaindex-cli, which comes installed with the llama-index python package:

llamaindex-cli download-llamapack LLMCompilerAgentPack --download-dir ./llm_compiler_agent_pack

You can then inspect the files at ./llm_compiler_agent_pack and use them as a template for your own project!

Code Usage

You can download the pack to a directory. NOTE: You must specify skip_load=True - the pack contains multiple files, which makes it hard to load directly.

We will show you how to import the agent from these files!
