The VC Read
Baseten is the purest bet on the 'inference is the real AI infrastructure' thesis: a $5B company in January, ~$13B by June, with annualized revenue up ~20x year over year. The growth is real because the tailwind is real — every team moving off closed APIs onto open-source models needs a production layer. The risk is that inference is the most contested layer in AI, with hyperscalers and Nvidia sitting directly upstream of Baseten's margins.
How Baseten makes money
Baseten runs usage-based AI inference: customers pay either for API consumption on open-source models or for GPU minutes/hours, with Baseten packaging autoscaling, observability, billing, and developer tooling around it.
Growth is driven by companies moving workloads onto open-source and custom models instead of closed APIs — Baseten is the production layer that makes that switch operationally viable, which is why its annualized revenue tripled in a single quarter.

- Modal & Replicate — Developer-first model-serving and compute platforms.
