Frequently Asked Questions about model-usage

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I track AI model costs for Codex and Claude locally?▼

You can track AI model costs locally by parsing JSON log data through the CodexBar CLI, which generates per-model cost summaries for Codex and Claude providers without requiring external cloud billing dashboards.

What is the best way to get a per-model cost breakdown for GPT-4 versus Claude?▼

The best way to get a per-model cost breakdown is by requesting an all-models summary, which analyzes JSON logs to compare individual model usage and expenditure across different providers like GPT-4 and Claude.

Do I need CodexBar installed to analyze local AI cost usage?▼

Yes, you need the CodexBar CLI installed and accessible on your system PATH to analyze local AI cost usage, as the Skill relies on this command-line tool to read and summarize the JSON log data.

Can I view just the current AI model usage instead of all historical data?▼

Yes, you can view just the current AI model usage by requesting a current summary, which restricts the JSON log analysis to only the most recent model's cost data rather than generating a comprehensive all-model report.
