This past week, two state-of-the-art (SOTA) foundation models were launched: Moonshot Labs' Kimi K3[1] and Alibaba's Qwen 3.8[2]. Both are allegedly close to Anthropic's Fable 5 in performance, and both will have their model weights released publicly in the coming weeks. Kimi K3 and Qwen 3.8 represent a strategic challenge to top-tier model developers and what they'll need to do to compete moving forward. They prove that the SOTA frontier is possible to attain with open models, and this represents a major threat, particularly to Anthropic, which risks struggling with product differentiation in the future. We'll explore foundation model economics and then their strategic implications given Kimi K3 and Qwen 3.8. Foundation models are incredibly expensive to build. They require researchers (i.e., payroll), compute (i.e., chips and data centers), and electricity to power the compute. Once a model is built, the biggest cost is inference: enabling your users to actually use the models. Payroll, compute, and electricity are still required, but the vast majority of marginal costs are limited to compute and electricity—since models aren't being updated, payroll costs are relatively low compared to when training the models. In other words, running an inference business requires you to optimize for two costs: electricity and data center compute. The more of the value chain you own, the more your variable costs become fixed costs. What are your options, then? First, you can lease data centers and pay for electricity. This is what Anthropic, Knowledge Atlas (makers of GLM 5.2), and Moonshot Labs (makers of Kimi K3) do; they do not own their own data centers or power plants. Another option is to build your own data centers, paying other suppliers for electricity. This is the Meta and Alibaba approach. Finally, you can also build your own power generators and own your data centers, like SpaceX. Your strategy impacts your cost base and thus your margin. In the first case, you make money by adding a margin to your customers' inference. Unfortunately, this means your costs scale with your revenue; your margin doesn't grow with your usage. Conversely, if you own the power plants and/or data centers, you make much of your inference cost base a fixed cost, so your margin can grow as more customers use your product more often. Your frontier lab's approach to margin has a huge impact on your long-term outcome.
