On this tutorial, we lean laborious on Collectively AI’s rising ecosystem to point out how rapidly we are able to flip unstructured textual content right into a question-answering service that cites its sources. We’ll scrape a handful of stay net pages, slice them into coherent chunks, and feed these chunks to the togethercomputer/m2-bert-80M-8k-retrieval embedding mannequin. These vectors land in a FAISS index for millisecond similarity search, after which a light-weight ChatTogether mannequin drafts solutions that keep grounded within the retrieved passages. As a result of Collectively AI handles embeddings and chat behind a single API key, we keep away from juggling a number of suppliers, quotas, or SDK dialects.
!pip -q set up --upgrade langchain-core langchain-community langchain-together
faiss-cpu tiktoken beautifulsoup4 html2text
This quiet (-q) pip command upgrades and installs every thing the Colab RAG wants. It pulls core LangChain libraries plus the Collectively AI integration, FAISS for vector search, token-handling with tiktoken, and light-weight HTML parsing by way of beautifulsoup4 and html2text, guaranteeing the pocket book runs end-to-end with out extra setup.
import os, getpass, warnings, textwrap, json
if "TOGETHER_API_KEY" not in os.environ:
os.environ["TOGETHER_API_KEY"] = getpass.getpass("🔑 Enter your Collectively API key: ")We verify whether or not the TOGETHER_API_KEY setting variable is already set; if not, it securely prompts us for the important thing with getpass and shops it in os.environ. The remainder of the pocket book can name Collectively AI’s API with out laborious‑coding secrets and techniques or exposing them in plain textual content by capturing the credentials as soon as per runtime.
from langchain_community.document_loaders import WebBaseLoader
URLS = [
"https://python.langchain.com/docs/integrations/text_embedding/together/",
"https://api.together.xyz/",
"https://together.ai/blog"
]
raw_docs = WebBaseLoader(URLS).load()
WebBaseLoader fetches every URL, strips boilerplate, and returns LangChain Doc objects containing the clear web page textual content plus metadata. By passing an inventory of Collectively-related hyperlinks, we instantly acquire stay documentation and weblog content material that may later be chunked and embedded for semantic search.
from langchain.text_splitter import RecursiveCharacterTextSplitter
splitter = RecursiveCharacterTextSplitter(chunk_size=800, chunk_overlap=100)
docs = splitter.split_documents(raw_docs)
print(f"Loaded {len(raw_docs)} pages → {len(docs)} chunks after splitting.")RecursiveCharacterTextSplitter slices each fetched web page into ~800-character segments with a 100-character overlap so contextual clues aren’t misplaced at chunk boundaries. The ensuing listing docs holds these bite-sized LangChain Doc objects, and the printout exhibits what number of chunks had been produced from the unique pages, important prep for high-quality embedding.
from langchain_together.embeddings import TogetherEmbeddings
embeddings = TogetherEmbeddings(
mannequin="togethercomputer/m2-bert-80M-8k-retrieval"
)
from langchain_community.vectorstores import FAISS
vector_store = FAISS.from_documents(docs, embeddings)
Right here we instantiate Collectively AI’s 80 M-parameter m2-bert retrieval mannequin as a drop-in LangChain embedder, then feed each textual content chunk into it whereas FAISS.from_documents builds an in-memory vector index. The ensuing vector retailer helps millisecond-level cosine searches, turning our scraped pages right into a searchable semantic database.
from langchain_together.chat_models import ChatTogether
llm = ChatTogether(
mannequin="mistralai/Mistral-7B-Instruct-v0.3",
temperature=0.2,
max_tokens=512,
)
ChatTogether wraps a chat-tuned mannequin hosted on Collectively AI, Mistral-7B-Instruct-v0.3 for use like every other LangChain LLM. A low temperature of 0.2 retains solutions grounded and repeatable, whereas max_tokens=512 leaves room for detailed, multi-paragraph responses with out runaway price.
from langchain.chains import RetrievalQA
qa_chain = RetrievalQA.from_chain_type(
llm=llm,
chain_type="stuff",
retriever=vector_store.as_retriever(search_kwargs={"ok": 4}),
return_source_documents=True,
)
RetrievalQA stitches the items collectively: it takes our FAISS retriever (returning the highest 4 related chunks) and feeds these snippets into the llm utilizing the easy “stuff” immediate template. Setting return_source_documents=True means every reply will return with the precise passages it relied on, giving us prompt, citation-ready Q-and-A.
QUESTION = "How do I exploit TogetherEmbeddings inside LangChain, and what mannequin identify ought to I go?"
consequence = qa_chain(QUESTION)
print("n🤖 Reply:n", textwrap.fill(consequence['result'], 100))
print("n📄 Sources:")
for doc in consequence['source_documents']:
print(" •", doc.metadata['source'])Lastly, we ship a natural-language question by means of the qa_chain, which retrieves the 4 most related chunks, feeds them to the ChatTogether mannequin, and returns a concise reply. It then prints the formatted response, adopted by an inventory of supply URLs, giving us each the synthesized clarification and clear citations in a single shot.
In conclusion, in roughly fifty traces of code, we constructed an entire RAG loop powered end-to-end by Collectively AI: ingest, embed, retailer, retrieve, and converse. The method is intentionally modular, swap FAISS for Chroma, commerce the 80 M-parameter embedder for Collectively’s bigger multilingual mannequin, or plug in a reranker with out touching the remainder of the pipeline. What stays fixed is the comfort of a unified Collectively AI backend: quick, reasonably priced embeddings, chat fashions tuned for instruction following, and a beneficiant free tier that makes experimentation painless. Use this template to bootstrap an inner data assistant, a documentation bot for purchasers, or a private analysis aide.
