Llama-3.1-8B-Instruct

Llama-3.1-8B-Instruct is Meta's instruction-tuned entry in the Llama 3.1 family, released on July 23, 2024 and distributed as the official `meta-llama/Llama-3.1-8B-Instruct` repository on Hugging Face under the Llama 3.1 Community License Agreement. Access to the weights is gated by a contact-information agreement, reflecting the community-license model Meta uses to balance broad availability with responsible use. The model is positioned within Meta's broader Llama 3.1 lineup as a compact, chat-aligned variant intended for developers who want a lightweight open model that can run locally or be self-hosted, rather than a frontier-scale system.

In practical terms, the 8B instruction-tuned variant targets general assistant use cases such as drafting, summarization, conversational Q&A, and tool-augmented workflows, where its smaller footprint makes it attractive for latency-sensitive or cost-sensitive deployments compared to larger Llama 3.1 siblings. Third-party leaderboards place it in mid-pack among tracked open models, with relative strengths in tool-calling scenarios and weaker showings in reasoning, coding, and math categories, which is consistent with its scale. The combination of Meta's open distribution, the Llama 3.1 community license, and the official documentation hub at llama.meta.com makes it a natural fit for teams that want a well-known base model they can fine-tune, distill, or serve on their own infrastructure.
