  • Together uses "organization/model-name" format, e.g. "meta-llama/Llama-4-Scout-17B-16E-Instruct" or "Qwen/QwQ-32B". See the Together model catalog for the exact ID.
  • The examples expect TOGETHER_API_KEY; rename it only if your application config maps the new variable.

About Vicuna 13B V1.5

Vicuna 13B V1.5, developed by LMSYS, is a large language model designed for chat assistance, fine-tuned from Llama 2 using the transformer architecture. It underwent supervised instruction fine-tuning with around 125,000 conversations from ShareGPT. The model excels in text generation, conversational dialogue, and Q&A tasks, primarily intended for research. While its responses are high-quality and polite, it may lack domain-specific insights, exhibit limited contextual understanding, and display inherited biases. Quantized versions of the model provide trade-offs between size, speed, and accuracy 129.
