Open source labs cracked the code: buy intelligence with capacity, not raw compute.
Kimi K3 runs a Mixture of Experts (MoE) architecture that only activates 16 out of 896 experts per token. You get massive model capacity without blowing your training budget on full dense compute.
This is the MoE advantage: sparse activation means you can scale model parameters way up while keeping FLOPs per token constant. Training cost stays linear, but model expressiveness scales with total expert count.
Why MoE is dominating:
- Dense models: every parameter fires every time = expensive at scale
- MoE models: route tokens to specialized experts = same training cost, way more capacity
Kimi K3 proves you can deploy near-trillion parameter models without trillion-dollar compute bills. The winning move is architectural efficiency, not just throwing more GPUs at the problem.
