About Spendens AI
What is Spendens AI?
SpendLens AI is an artificial intelligence cost optimization platform that analyzes model spending across engineering workloads and tests candidate models before switching.
What Spendens AI does
The platform connects to provider accounts such as OpenAI and Anthropic to attribute spend by project, model, and API key without proxying model traffic. It features Compare Mode to test candidate models in staging for cost, speed, and quality matches, and offers Python and Node.js SDKs to collect runtime telemetry without storing prompts or message content.
Who Spendens AI is for
Engineering teams, developers, and SaaS teams wanting to track AI spend, compare cheaper models, and validate quality.
How Spendens AI works
Users connect provider reporting data through Account Connect, identify expensive workloads, evaluate candidate models in Compare Mode using their own provider keys in staging, and pilot validated model substitutions.
