AICost Skill
Use the aicost CLI tool to look up current AI model pricing, convert currencies automatically, and recommend/compare models based on a live-updating pricing database.
When to use
- When the user asks about the price, cost, or pricing of an AI API (like GPT-5.5, Claude Opus 4.7, Gemini 3.1, DeepSeek R1).
- When the user wants to compare two or more models by cost.
- When the user wants to know the "cheapest" or "best" AI model for a specific task.
- When you (the Agent) are helping the user decide on an AI model based on ROI.
- When the user asks about image, video, or audio generation costs (Imagen, Veo, Lyria, DALL-E, Whisper, TTS).
How to use
Run the following terminal commands to execute the tool:
- Verify or Sync Latest Data:
aicost sync (Always run this if the user asks for the "latest" or "most recent" prices)
- List all models and prices:
aicost list --currency <target-currency>
- Compare two models side-by-side:
aicost compare <model1-id> <model2-id> --currency <target-currency>
- Calculate a specific model's cost:
aicost calc <model-id> --input <tokens> --output <tokens> --currency <target-currency> For image/video/audio models, use --units instead of --input/--output.
- Recommend models based on a task:
aicost recommend "<task description>" --currency <target-currency>
Prerequisites
The aicost CLI must be pre-installed on the system. If not found, advise the user to install it manually.
