Basic interaction with LLMs in Java

This folder contains Java examples for interacting with OpenAI, Anthropic, Google Gemini, and local Ollama models.

Requirements

• Java 21+
• Maven 3.9+
• Corresponding API keys are set as environment variables (OPENAI_API_KEY, ANTHROPIC_API_KEY, and GEMINI_API_KEY) for cloud examples
• Ollama installed locally for the local model example

Examples

• OpenAiGptBasic.java: Basic interaction with OpenAI GPT models.
• OpenAiGptStreaming.java: Streaming responses from OpenAI GPT models.
• AnthropicClaudeBasic.java: Basic interaction with Anthropic Claude models.
• AnthropicClaudeStreaming.java: Streaming responses from Anthropic Claude models.
• GoogleGeminiBasic.java: Basic interaction with Google Gemini models.
• GoogleGeminiStreaming.java: Streaming responses from Google Gemini models.
• OllamaLocalBasic.java: Basic interaction with a local LLM using Ollama.
• OllamaLocalStreaming.java: Streaming responses from a local LLM using Ollama.
