Baseten is reportedly nearing a $1.5 billion funding round at a $13 billion valuation, according to TechCrunch. The company builds infrastructure for AI inference, a market that has become central as model usage scales.

The reported round reflects investor appetite for the serving layer of AI. Training gets much of the attention, but inference is where models become products and where cost, latency, and reliability determine margins.

If completed, the raise would reinforce the idea that the AI infrastructure boom is shifting from model creation toward the platforms that run models at scale.
