Meta Releases a 405-Billion-Parameter Model You Can Actually Download. The Catch? You Will Need a Data Center.
Meta has released Llama 3.1 with 405 billion parameters under a commercial license. The model is available for free download. Small teams may fine-tune and self-host it without per-token API fees, though the hardware requirements remain substantial.
This illustrates the tension between open weights and operational reality. The license democratizes access to the model file, not to the infrastructure to run it. You must learn to distinguish between legal availability and practical deployability when evaluating any open-source AI claim.

Step 1: Visit ai.meta.com/blog/meta-llama-3-1 and read the license terms to understand what commercial use is permitted. Step 2: Navigate to the model download page and observe the hardware requirements listed for the 405B variant. Step 3: Use the free Llama 3.1 8B or 70B variant through a consumer interface such as Meta AI or a cloud notebook to test its reasoning on a task in your domain, noting where it fails against the API models you currently pay for.
