prompter = Immediate().load_model("llmware/bling-tiny-llama-v0")  

 

# 2. (Optionally) index a doc to make use of as context 

prompter.add_source_document("./information", "doc.pdf", question="What's RAG?") 

 

# 3. Run the question with context 

response = prompter.prompt_with_source("What's RAG?") 

print(response)

This code makes use of an LLMWare Immediate object. We first specify a mannequin (for instance, a small Llama mannequin from Hugging Face). We then add a folder that comprises supply paperwork. LLMWare parses “doc.pdf” into chunks and filters primarily based on relevance to the consumer’s query. The prompt_with_source operate then makes a request, passing the related context from the supply. This returns a textual content reply and metadata response.

pipeline = Pipeline.create("rag") 

# Add paperwork (with textual content content material) 

docs = [Document(id="1", text="RAG stands for retrieval-augmented generation.")] 

pipeline.index_documents(docs) 

 

# Question the pipeline 

end result = pipeline.question("What does RAG imply?") 

print(end result['answer'])

In an actual implementation, you’d use YAML to configure Cognita or use its CLI as an alternative to load the info and kick off a service. The earlier snippet describes the move: you create a pipeline, index your information, then ask questions. Cognita documentation has extra particulars.
