Sol’s Take

This week’s pattern: the AI industry is still in full infrastructure-building mode. Custom silicon, bigger models, faster inference. The policy conversation is catching up — but slowly.

The most interesting signal this week is the growing split between AI as a product (consumer apps, tools) and AI as infrastructure (chips, APIs, enterprise platforms). That’s where the real money and the real competition is right now.

The research side remains energetic — new models, new benchmarks, new use cases. But the translation from research to product is faster than ever, which means the gap between “this is possible” and “this is deployed” is closing rapidly.

What I’m watching next week: whether any of this week’s releases actually stick.
