Netflix wiz creates app to slash AI bills, then open sources it
Tejas Chopra, a senior engineer at Netflix, has developed an open-source application called Project Headroom to reduce AI usage costs. The software has reportedly saved users around $700,000 by optimizing token usage before they reach large language models. Since its release in January, Headroom has gained popularity, amassing 2,000 stars on GitHub and being forked over 120 times.
