Llama 2 established the American open-weight precedent
Published 18 JUL 2023 · Curated 22 JUL 2026
What the source reports
Meta's July 2023 announcement made Llama 2 weights and starting code available for research and most commercial uses through a custom community license.
Editorial analysis
Meta repeatedly called the release open source, but the license included use restrictions and a large-platform condition. The historically accurate description is an unusually broad open-weight release, not an unqualified open-source baseline.
Why it matters
Chinese labs did not invent open-weight distribution. Llama 2 shows that a major American platform company pursued the same ecosystem strategy before the present US–China framing hardened.
