Coinbase CEO Brian Armstrong discloses the company is routing AI workloads through an LLM gateway that defaults to Chinese open-weight models like GLM 5.2 and Kimi 2.7 for cost efficiency, reserving frontier models only for complex planning tasks.

Claims
- Coinbase is experimenting with defaulting to Chinese open-weight models such as GLM 5.2 and Kimi 2.7 through its internal LLM gateway.
- Coinbase routes prompts by difficulty, using frontier models for planning while treating them as overkill for execution tasks.
- Frontier models are explicitly characterized by Armstrong as unnecessarily expensive for routine AI execution workloads.
- Infrastructure advantages allow China to build data centers faster with fewer permitting and labor constraints than Western counterparts, per Perplexity CEO Aravind Srinivas.
Key quotes
He explicitly says frontier models may be needed for planning but can be 'overkill' for execution.
China can build data centers a lot faster. Power is not a problem. Permits are not a problem. People are not a problem. Labor is not a problem. Expertise is not a problem.
