Moonshot’s Kimi K3 ships open weights, but self-hosting needs 1.4TB and 18+ GPUs

- Moonshot released Kimi K3 open weights, described here as the largest open-weight model yet.
- The post says it has 2.8T parameters, a Modified MIT license, 91.2% on BrowseComp, and the best published agentic score at release.
- It also argues that despite the “open” label, self-hosting is impractical for most teams: the weights reportedly need 1.4 TB of storage and 18+ enterprise GPUs just to load.
- The author’s takeaway is that most people will use the API, so “open weights” still do not equal control over inference or data.
