Cost.dev Adds LLM Cost Awareness to AI Agents, Extends Infracost Model
June 4, 2026
Cost.dev (YC W21, formerly Infracost) applies the shift-left cost visibility model to AI agent calls, surfacing per-call LLM costs to developers before and during agent execution. The tool targets the same FinOps pattern that made Infracost useful for Terraform.
HOW THIS AFFECTS YOU
●
builderYou can instrument agent pipelines with cost.dev to get per-call LLM spend visibility without building custom cost tracking.
●
founderAs LLM inference costs become a meaningful COGS line, tooling that attributes spend to specific agent actions will matter for margin management.
