Llama-3.3-70B-Instruct

Llama 3.3 70B Instruct is Meta's open-weights flagship instruction-tuned model, built as a dense Transformer with 70 billion total and active parameters. Released under the Llama 3.3 Community License, it is positioned by Meta to match the capabilities of the much larger Llama 3.1 405B on industry benchmarks while using roughly one-fifth of the compute, making it an attractive middle ground for teams that need strong reasoning and coding without stepping up to frontier-scale hardware.

In practical terms, the model is designed for flexible deployment, including local hosting through vLLM, Ollama, and llama.cpp, and can run in 4-bit Q4_K_M quantization on a single 48GB GPU, dual 24GB RTX 3090/4090 cards, or a 64GB Mac Studio. It supports tool calling and structured JSON output, suiting it to on-premise enterprise workflows, data-sensitive applications, and developer tooling where an open-weights foundation is preferred over a fully closed alternative.
