Llama 3.1 8B Instruct

by Meta

Announcement · All Meta releases

Llama 3.1 8B Instruct is Meta's production-grade lightweight model, released July 2024. With 8 billion parameters and a 131,072-token context window, it offers a strong cost-to-capability ratio, with solid instruction following and reasoning in a compact footprint. The model supports tool calling and structured output, enabling agentic workflows and programmatic integration without moving to larger models. It handles general-purpose tasks including summarization, question answering, code generation, and classification with competitive quality for its size. Its open-weight design and multilingual training make it suitable for fine-tuning and on-premise deployment. It is a common pick where compute is limited yet enough capability remains for diverse downstream tasks beyond simple text generation.
