It binds a Metal-enabled libllama.dylib via the Foreign Function & Memory API (FFM) and supports Mistral and Gemma GGUF models locally. The JAR can run as a CLI tool, expose OpenAI- and Anthropic-compatible HTTP endpoints with a -serve flag, or be embedded into other Java apps via ServiceLoader with no compile-time dependency. No Python, no Ollama, no containers required. ## Full article daily.dev links to this article rather than hosting it.
