Amazon CTO Says Companies Shift to Cheaper Open-Source AI Models

Amazon chief technology officer Werner Vogels said companies are moving from expensive proprietary AI models to cheaper open-source alternatives. He made the remarks in an interview on the sidelines of the UN’s AI for Good summit. Vogels described the change in direct terms.

“We see a shift happening between the cheaper open source models and the bigger expensive models,” he said. He added that cost must factor into system design. “Cost is a very important part of your architecture, you need to take that into account,” Vogels said.

“Do you really need to have the biggest, highest‑end model to solve this? ” Fortune.com reported that Uber exhausted its entire 2026 AI budget within four months. An unnamed company spent half a billion dollars on AI in a single month after failing to limit employee usage.

Vogels also highlighted transparency as a growing priority. “Transparency becomes extremely important,” he said. ” He noted the issue matters most in sectors serving vulnerable communities. “If these people serve vulnerable communities.

If they don’t trust the system, they won’t use it,” Vogels said. At the same summit Amazon launched an open-source AI tool that links the AWS Registry of Open Data to AI assistants for natural-language searches. The registry holds more than 1,100 datasets from NASA, NOAA, and the NIH.

The tool allows queries for satellite imagery or genomics datasets that meet specific licensing rules.
