• agent-loop-cost-calculatorAgent LLM Loop Cost Calculatorread-only

  Use for LLM inference/reasoning cost per successful multi-step agent task, including failure overhead and context growth across turns. Use agent-workflow-cost-calculator for iPaaS/app-action/MCP orchestration fees. Use automation-cost-calculator for generic Zapier/Make/n8n workflow billing.

• agent-workflow-cost-calculatorAgent Workflow Platform Cost Calculatorread-only

  Use for automation-platform/iPaaS cost of an AI agent workflow, including app-action fan-out and MCP tool-call accounting, explicitly excluding LLM token spend. Use automation-cost-calculator for generic non-agent workflow billing. Use agent-loop-cost-calculator for LLM inference/reasoning cost per successful multi-step agent task.

• automation-cost-calculatorWorkflow Automation Platform Cost Calculatorread-only

  Use for generic or non-agent recurring workflow platform billing across Zapier task billing, Make credit billing, and n8n execution billing. Use agent-workflow-cost-calculator instead when the workflow is explicitly an AI agent with app actions or MCP tool calls. Use agent-loop-cost-calculator instead when the question is about LLM inference/reasoning cost per successful agent task.

• context-window-plannerContext Window Plannerread-only

  Use when a user needs to know whether a document plus prompt plus output fits within a model's context window, or wants a strategy recommendation (truncate/summarize/rag/chunk).

• eval-cost-calculatorEvaluation Cost Calculatorread-only

  Use when a user needs to budget an LLM evaluation run. Given samples/models/trials, returns total cost, per-run cost, and parallel time estimate.

• fine-tune-roi-calculatorFine-Tune ROI Calculatorread-only

  Use when a user is considering fine-tuning vs prompt engineering. Returns training cost, monthly inference savings, months-to-ROI, and breakeven volume.

• observability-cost-calculatorLLM Observability Cost Calculatorread-only

  Use when a user needs to budget LLM observability tooling. Returns monthly cost at given request volume with retention adjustment.

• provider-cost-calculatorLLM Provider Cost Calculatorread-only

  Use when a user asks what an LLM workload costs on a specific provider/model, or wants to compare cost across providers. Given tokens per call and call volume, returns monthly cost plus a tier comparison table.

• quantization-calculatorQuantization Calculatorread-only

  Use when a user is planning to quantize an LLM to fit on smaller hardware. Given parameter count and precision transition, returns VRAM requirement, speedup estimate, and approximate quality delta.

• rag-pipeline-cost-calculatorRAG Pipeline Cost Calculatorread-only

  Use when a user needs end-to-end RAG cost estimation (embedding + vector store + generation). Returns monthly cost with breakdown and dominant-component identification.

• self-host-breakeven-calculatorSelf-Host Breakeven Calculatorread-only

  Use when a user is deciding between API usage and self-hosted GPU inference at a given volume. Returns breakeven token volume, monthly cost comparison, and go/no-go recommendation.

• token-counterToken Counterread-only

  Use when a user asks how many tokens a given text will consume, or needs to estimate prompt size before pricing a workload. Given text and tokenizer family, returns low/high token range and byte-level measurements.
