Llama 3.1 8B Instruct
Llama 3.1 8B Instruct is Meta's instruction-tuned mid-size model from the 3.1 generation, notable for its extended 128K context window that significantly expanded what small open-source models could handle. It provides a strong balance between capability and resource cost, making it a popular choice for developers who need meaningful context length without the expense of a 70B+ model.
The model supports tool use and function calling, positioning it for agentic workflows and RAG pipelines on lightweight infrastructure. Instruction following quality improved substantially in Llama 3.1, and the 8B variant offers competitive performance on general reasoning, coding assistance, and multilingual tasks for its parameter class.
