Model Usage

AI Models

Track AI model costs and token usage over time

• Per-model cost breakdown and totals
• Daily and session-level summaries
• JSON export for expense tracking

What You Can Do

• Per-model cost breakdown - See exactly what each model costs in your sessions
• Current model usage - Most recent session's model and cost details
• Full model breakdown - Complete historical cost analysis across all models
• Multiple providers - Track usage for Codex and Claude Code
• Flexible input - Read from CodexBar CLI directly, from file, or stdin
• Output formats - Text for readability or JSON for scripting

Try Asking

• "Show my current Codex session's model usage and cost"
• "Break down costs across all Claude models I've used"
• "What's my total spend for today?"
• "Export usage data as JSON"
• "Show token counts for each model"

Pro Tips

• JSON output is perfect for expense tracking and budget monitoring
• Regular monitoring prevents surprise bills from expensive models
• Compare model costs to make informed choices about which to use
• File input enables historical analysis across multiple sessions
• Token counts help identify opportunities to optimize prompt efficiency
