Meta's open-source LLM family with strong performance rivaling proprietary models. Available for local deployment and research.
What is Llama 3?
What is Llama 3?
Llama 3 is Meta's open-source large language model family, available in 8B and 70B parameter sizes (with larger models following). It delivers performance that rivals leading proprietary models on many benchmarks while being freely available for download, local deployment, and commercial use — making it the most capable open-source LLM option available.
The Open-Source LLM Standard
Llama 3 represents a major milestone for the open-source AI community. Its 70B instruction-tuned model competes with GPT-3.5 and approaches GPT-4 on several benchmarks, while the 8B model is small enough to run efficiently on consumer hardware. This combination of capability and accessibility has made Llama 3 the foundation model of choice for developers building local AI applications.
- 8B and 70B parameter models with instruction and chat tuning
- 128K context window (Llama 3.1+)
- State-of-the-art open-source benchmark performance
- Available on Hugging Face and Meta's website
- Permissive license allowing commercial use (with restrictions)
Key Features
Free model weights available for download and commercial deployment.
Run on local hardware with tools like Ollama, LM Studio, and llama.cpp.
Choose from 8B (efficient) to 70B (maximum quality) parameter models.
Fine-tune for specific domains using LoRA and other efficient methods.
128K token context window in Llama 3.1 and later versions.
Who Uses Llama 3?
