Llama 3.3 70B Instruct
Llama 3.3 70B Instruct is Meta's late-2024 refresh of the Llama 3 70B line — same architecture, new post-training recipe that closed most of the gap to the Llama 3.1 405B flagship. It remains the pragmatic open-weights workhorse: strong general quality, fits on 2x H100, and well-supported by every inference stack.

Frequently asked questions
What changed in Llama 3.3 vs Llama 3.1 70B?
Llama 3.3 70B uses the same base weights and architecture as Llama 3.1 70B, but with a new post-training pipeline (improved SFT + DPO) that lifts reasoning, math, and tool-use benchmarks close to the 405B model.
Is Llama 3.3 70B free to use commercially?
Yes — the Llama 3 community license permits commercial use up to a named MAU threshold (700M+ users), which covers essentially all enterprise deployments.
How does Llama 3.3 compare to Llama 4?
Llama 4 Maverick and Scout use Mixture-of-Experts and are multimodal. Llama 3.3 is dense and text-only but remains the more mature production option with broader tool support.
