Moonshot AI released Kimi K3, a 2.8 trillion-parameter model on Hugging Face, making it the largest AI model ever freely downloadable. The model uses sparse activation (only 16 of 896 blocks per request) to reduce compute to ~50B parameters, matches closed models on benchmarks, and comes with a commercial license targeting cloud providers earning over $20m annually.

This Wire brief sits within Fusion42's coverage of AI Frontier Models. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.

◆ The Wire takeaway

You can now download a 2.8 trillion-parameter model that matches OpenAI and Anthropic on most benchmarks, but running it requires eight GPU servers and $m in hardware. Moonshot has opened the weights to everyone whilst locking the $20m+ cloud resellers into commercial negotiations—watch whether AWS and Azure actually sign, or whether this becomes a credible threat to their model monopoly.
