from sklearn.metrics.pairwise import cosine_similarity

# Initialize the Anthropic client
client = anthropic.Anthropic(api_key="your_api_key_here")

# Sample knowledge base (replace with your own documents)
knowledge_base = [
    "Claude V3 is an AI model developed by Anthropic.",
    "Opus is the most capable model in the Claude V3 family.",
    "RAG stands for Retrieval-Augmented Generation.",
]

# Create TF-IDF vectorizer
vectorizer = TfidfVectorizer()
kb_vectors = vectorizer.fit_transform(knowledge_base)

def retrieve_relevant_info(query, top_k=2):
    query_vector = vectorizer.transform([query])
    similarities = cosine_similarity(query_vector, kb_vectors)
    top_indices = np.argsort(similarities[0])[-top_k:][::-1]
    return [knowledge_base[i] for i in top_indices]

def rag_with_claude(query):
    relevant_info = retrieve_relevant_info(query)
    context = "\n".join(relevant_info)
    
    message = client.messages.create(
        model="claude-3-opus-20240229",
        max_tokens=300,
