We tracked 200K AI requests. Here's where the money actually goes
CostLens, a tool initially designed to track OpenAI spending, has evolved into a platform that attributes AI costs by feature and developer, routes requests to cost-efficient models, and measures productivity through coding activity. After analyzing 200,000 AI requests, the team found significant overspending on simple tasks and reduced costs by 30-40% using smart model routing. The tool integrates easily with existing workflows and includes a Slack-based kill switch to prevent runaway AI expenses.
- ▪CostLens now provides cost attribution by feature and developer, not just overall spending.
- ▪Smart routing redirects simple prompts to cheaper models, achieving 30-40% cost savings.
- ▪52% of AI requests analyzed were simple tasks running on expensive models.
- ▪Sessions with no output accounted for 15% of AI spending.
- ▪The platform includes a Slack kill switch to pause high-spend agent sessions.

Here's where the money actually goes #ai #productivity #devtools #openai Six months ago I posted here about CostLens — a tool to reduce OpenAI costs. Since then, we've completely rebuilt it based on one question a VP asked our team: "How much faster are we delivering with AI? What's the number?" Nobody could answer. We had cost dashboards, but no way to connect spend to output. So we built that.
