Understand your
AI systems.
Trace requests, master your token economics, attribute AI spend to features and customers, and identify optimisation opportunities across every AI workflow.
AI systems become difficult to understand surprisingly quickly.
The first AI request is easy. The hundredth isn't.
Once workflows involve multiple models, prompts, retries, tools, customers, and teams, simple questions get hard to answer:
P PromptLayer is built to answer those questions.
Observability and cost intelligence,
in one system.
PromptLayer sits between AI observability and AI FinOps — connecting what your system does with what it costs and who owns it.
Know what changed and where to look.
Surface spend increases, growth drivers, and recommendations in one place — each with a confidence indicator so you know how much to trust it.
See complete execution paths.
Understand how requests move through multi-step AI systems. Visual waterfall views reveal exactly where time and cost are spent.
Track estimated spend, everywhere.
Follow estimated AI spend across models and providers, then break it down by workflow, feature, customer, team, and cost centre.
Understand who owns spend.
Allocate costs to products, customers, teams, and features. Move beyond raw token counts and into real accountability.
Find what to optimise first.
Identify opportunities to reduce spend with quantified savings estimates, and investigate the workflows driving the most cost.
Know how much to trust the numbers.
Track pricing coverage, attribution coverage, and confidence levels so you always know how trustworthy your spend data is.
PromptLayer explains spend — it doesn't just report it.
The same data behind your traces becomes answers to the questions teams actually ask.
