ThinLLM - Unified LLM API Client

ThinLLM is a unified LLM API client that enables seamless integration of multiple AI providers into your Unity projects with a single, consistent interface. It lets developers call OpenAI, Anthropic Claude, Google Gemini, Azure OpenAI, AWS Bedrock, and local LLMs (GGUF models) through one simple Completion() method, with no code changes required when switching providers.

Core Features:

・Unified API Interface: Single Completion("{provider}/{model-name}", messages) method works across all 6 supported LLM providers

・Real-time Streaming: Token-by-token response streaming for responsive UI updates

・Local LLM Support: Run GGUF models offline via LLamaSharp - no API costs, no internet required

・Built-in Model Downloader: Download GGUF models directly from URL within Unity Editor

・Zero External Dependencies: All required libraries are pre-bundled in the package

ThinLLM is perfect for building intelligent NPCs, dynamic dialogue systems, AI assistants, or any application that needs flexible LLM access. The simple model format ("{provider}/{model-name}") makes it trivial to experiment with different providers and find the best fit for your project.

A demo scene with a working chat interface is included so you can start testing immediately out of the box.
