OpenLLaMA is a permissively licensed (Apache-2.0) open reproduction of Meta AI's LLaMA, releasing 3B, 7B, and 13B pretrained model weights trained on the RedPajama dataset. It provides PyTorch weights for Hugging Face transformers and JAX weights for EasyLM, usable as drop-in replacements for LLaMA.

Use cases

• download permissively licensed llama weights
• use an open source alternative to meta llama
• fine-tune a 7b open source language model
• run llama weights without meta's restrictive license
• compare open llama reproduction against original llama benchmarks
• get jax weights for easylm training

When to choose

• you need LLaMA-style model weights under a permissive Apache-2.0 license
• you want drop-in replacements for LLaMA in Hugging Face transformers or EasyLM
• you need small-to-mid size open LLMs (3B/7B/13B) for research or fine-tuning

When to avoid

• you need code generation performance out of the box (v1 tokenizer struggles with code tasks)
• you want the newest open models with instruction tuning or chat capabilities
• you lack the GPU resources to run multi-billion-parameter models
