LoomLens AI™ — Prompt Cost Estimator

What It Does

Estimates the exact cost in USD of running any prompt across 19+ AI models — before you spend a single token. Shows input tokens, output tokens, cached tokens, and cost per model for low/mid/high complexity bands.

When to Use

  • Before running a large prompt across multiple agents
  • When optimizing for cost in production pipelines
  • When comparing models for a new use case
  • After prompt changes to check budget impact

Syntax

In chat, type:

/loomlens Estimate the cost of this prompt across GPT-4o and Claude Sonnet 4

Free Tier

3 estimates/day free with any Signalloom API key (no card required).

Output

Returns cost breakdown per model:

  • Input / Output / Cached token estimates
  • Low / Mid / High cost bands
  • Cheapest model recommendation
  • Savings vs most expensive option
