Inference cost diagnosis

Croutons can evaluate where inference spend concentrates across models, agents, retries, and context size — and recommend routing and workload changes.

Problem

Inference spend rises faster than useful output because expensive models, oversized context, and retry loops are applied without workload-level diagnosis.

Operational symptoms

• Token and API spend growing faster than request volume
• Frontier models used for routine classification or extraction
• Unexplained cost spikes after agent or retrieval changes
• No per-workflow cost attribution

Who experiences it

Engineering and FinOps teams running multi-model AI in production

What Croutons evaluates

• Task class versus model tier
• Fan-out and retry amplification
• Context window size and retrieval payload cost
• Low-value calls on high-cost models

Inputs required

• Sample traces or logs with model, tokens, and latency
• Workflow or agent descriptions
• Current routing or gateway rules if available
• Cost reports or invoice exports for the period under review

Method

Map completed tasks to model selection, token cost, and amplification sources. Cluster waste by workflow class. Propose the lowest-cost model tier that meets stated quality thresholds for each class.

Deliverables

• Inference cost map by workflow and model tier
• Ranked waste drivers
• Recommended routing and context controls
• Pilot measurement plan for cost deltas

Expected outcome

A clearer picture of where spend concentrates and a prioritized set of controls teams can implement without claiming fixed percentage savings.

Limitations

• Savings depend on your workload mix and quality thresholds
• Does not replace FinOps tooling or billing systems
• First diagnosis uses samples — not continuous production metering unless later engaged
