2. Tokenizer

• The tokenizer is responsible for preprocessing input text data.
• It splits the input text into individual tokens, such as words or subwords.

• Zero data leakage – No API keys, no external calls.
• Low latency – Inference happens on your own GPU/CPU.
• Cost control – No per-token pricing.
• Full control – You can swap models (Llama 3, Phi-3, etc.) without changing Java code.

• Enables low-latency inference for medium-sized models (e.g., LLaMA derivatives, Mistral variants) without cloud round trips.
• Offers energy-efficient inference, allowing desktop or edge deployment.
• Limits: very large models (tens of billions of parameters) may exceed device memory or run slowly; quantized models often perform best.

• REST/gRPC API: Ollama exposes local endpoints developers can call from Java via HTTP clients (HttpClient, OkHttp) or gRPC stubs.
• Command-line invocation: Java apps can spawn Ollama CLI processes, passing prompts and receiving outputs via stdout/stderr.
• JNI or native bindings: Less common due to complexity, but possible if a tighter integration with native runtime offers performance gains.
• WebSocket/streaming: For streaming token outputs, Java WebSocket clients can connect to Ollama’s streaming interfaces if provided.

Pattern C: Direct OllamaC Binding via JNA (Experimental)

If you truly need OllamaC Java work in the literal sense, you can call the C library using Java Native Access (JNA). This skips HTTP overhead entirely. The Ultimate Guide to Running Local LLMs: Mastering
