The weights for Grok 2 were released on 08/23/25, and Elon Musk tweeted that "Grok 3 will be made open source in about six months." When, if ever, will the weights become publicly available?

Resolution criteria

• Resolves to the earliest (US Eastern) calendar date when any model explicitly branded “Grok 3” (e.g., Grok‑3, Grok‑3‑mini, Grok‑3‑Think) has its weights made publicly downloadable by xAI.

• “Publicly available” means anyone can download the full model weights (a free account/license click-through is fine). Not sufficient: API-only access, gated “request access,” closed research programs, code without weights, or third‑party leaks/mirrors not acknowledged by xAI.

• If multiple Grok 3 variants’ weights drop at different times, resolve to the first variant released. If timestamps conflict, use the earliest time visible on the official hosting/announcement page.

Considerations

• xAI has used “open source/open weights” loosely; for resolution here, license terms can be restrictive as long as the weights are downloadable by the general public. Example: Grok‑2’s Hugging Face page uses a “Grok 2 Community License.” (huggingface.co)

• All dates are in US Eastern Time.
