Overview

TogetherLLMService provides access to Together AI’s language models, including Meta’s Llama 3.1 and 3.2 models, through an OpenAI-compatible interface. It inherits from OpenAILLMService and supports streaming responses, function calling, and context management with optimized open-source model hosting.
