Known tools 12

token-counter

Use when a user asks how many tokens a given text will consume, or needs to estimate prompt size before pricing a workload.

provider-cost-calculator

Use when a user asks what an LLM workload costs on a specific provider/model, or wants to compare cost across providers.

self-host-breakeven-calculator

Use when a user is deciding between API usage and self-hosted GPU inference at a given volume.

context-window-planner

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).

quantization-calculator

Use when a user is planning to quantize an LLM to fit on smaller hardware.

fine-tune-roi-calculator

Use when a user is considering fine-tuning vs prompt engineering.

eval-cost-calculator

Use when a user needs to budget an LLM evaluation run.

observability-cost-calculator

Use when a user needs to budget LLM observability tooling.

rag-pipeline-cost-calculator

Use when a user needs end-to-end RAG cost estimation (embedding + vector store + generation).

automation-cost-calculator

Use when a user needs to compare workflow automation platform cost across Zapier task billing, Make credit billing, and n8n execution billing for a recurring workflow shape.

agent-workflow-cost-calculator

Use when a user needs to estimate automation-platform cost for an agent workflow, including app-action fan-out and MCP tool-call accounting, separate from LLM token spend.

agent-loop-cost-calculator

Use when a user is running multi-step LLM agents and needs cost per successful task.
