Llama-3.1-8B-Instruct
MetaLlama-3.1-8B-Instruct is an instruction-tuned 8-billion-parameter Llama 3.1 model for chat and assistant workflows, post-trained with supervised fine-tuning and reinforcement learning with human feedback on Meta's Llama 3.1 base. It supports a 128K-token context window. Weights are gated behind a manual access request rather than an open download.
Openness
3 high confidence- weights
- open(downloadable)
- data
- closed
- code
- partial(no training pipeline)
- license
- Llama-3.1-Community(non-OSI
Meta releases the weights under the Llama 3.1 Community License, non-OSI and requiring a separate license from Meta above 700 million monthly active users. That cap permits commercial use below the threshold rather than forbidding it, so the release counts as open weights rather than fully open source: the training data and pipeline are unpublished, and the manual access gate on the repository does not itself reduce its openness.

Model card and repo tags show `license:llama3.1`; the license body reads "is greater than 700 million monthly active users in the preceding calendar month, you must request a license from Meta"; the repository is gated ("gated":"manual" in the API record, not on this page), and the card lists no training pipeline.

Model card: "Llama 3.1 was pretrained on ~15 trillion tokens of data from publicly available sources" and the fine-tuning data "includes publicly available instruction datasets, as well as over 25M synthetically generated examples"; the corpora themselves are not released. Searched the body for a training pipeline, training code or post-training data release: none.
Adoption
4 high confidenceAdoption is read from Hugging Face downloads on the sole declared checkpoint, meta-llama/Llama-3.1-8B-Instruct. No other artifact is declared for this record, so the reading does not draw on any additional distribution surface that might place it higher.

Capability
3 medium confidenceA competent 2024-generation 8B chat model, a long way below the 2026 frontier and below the larger Llama 3.1 SKUs. The card's benchmark table gives Llama 3.1 8B Instruct MMLU 69.4 (5-shot, macro_avg/acc) against 83.6 for the 70B and 87.3 for the 405B, and publishes no reasoning or agentic frontier scores.
