        **WordLlama** is a fast, lightweight NLP toolkit that handles tasks like fuzzy deduplication, similarity, and ranking with minimal inference-time dependencies and is optimized for CPU hardware.

        For more details, visit the [WordLlama GitHub repository](https://github.com/dleemiller/WordLlama).

        ## Examples

        **Calculate Similarity**

        ```python
        from wordllama import WordLlama

        # Load the default WordLlama model
        wl = WordLlama.load()

        # Calculate similarity between two sentences
        similarity_score = wl.similarity("i went to the car", "i went to the pawn shop")
        print(similarity_score)  # Output: 0.06641249096796882
        ```

        **Rank Documents**

        ```python
        query = "i went to the car"
        candidates = ["i went to the park", "i went to the shop", "i went to the truck", "i went to the vehicle"]
        ranked_docs = wl.rank(query, candidates)
        print(ranked_docs)
        # Output:
        # [
        #   ('i went to the vehicle', 0.7441646856486314),
        #   ('i went to the truck', 0.2832691551894259),
        #   ('i went to the shop', 0.19732814982305436),
        #   ('i went to the park', 0.15101404519322253)
        # ]
        ```

        **Additional Inference Methods**

        ```python
        # Fuzzy Deduplication
        wl.deduplicate(candidates, threshold=0.8)

        # Clustering with K-means
        wl.cluster(docs, k=5, max_iterations=100, tolerance=1e-4)

        # Filtering Candidates
        wl.filter(query, candidates, threshold=0.3)

        # Top-k Candidates
        wl.topk(query, candidates, k=3)
        ```
