The open-weight frontier keeps escalating
Moonshot released Kimi K3, reported as a 2.8-trillion-parameter mixture-of-experts model with open weights following release1. It follows K2.6 in April, a 1T-parameter model with 32B active parameters and a 256K context window2.
Open weights move demand from training to serving, and serving is far more price-sensitive than training. Every capable open model that ships enlarges the population of buyers who care about the difference between $1.50 and $3.00 an hour — which is the population a reference rate serves.
