Updated through the day. Every headline links straight to the source. The two lines underneath are ours.
This is a direct shot at the consolidation narrative around frontier models. Open-weight 400B-class models are now commoditized enough that the gap between closed and open is performance, not capability class. For operators on a budget or with latency constraints, this changes the math on whether to run in-house. For API companies, the margin compression just got real.
Open-weight is winning on volume, but closed-weight models at the high end (Kimi K3 priced four times above open-weight average) are capturing spend growth. This means the market is bifurcating: builders optimizing for cost go open-weight, builders optimizing for capability pay premium for closed-weight. For infrastructure players: you need both lanes to capture the full market. For model labs: open-weight competitiveness is forcing pricing discipline everywhere.
