Model usage

Overview

Get per-model usage cost from CodexBar's local cost logs. Supports "current model" (most recent daily entry) or "all models" summaries for Codex or Claude.

TODO: add Linux CLI support guidance once CodexBar CLI install path is documented for Linux.

Quick start

1. Fetch cost JSON via CodexBar CLI or pass a JSON file.
2. Use the bundled script to summarize by model.

python {baseDir}/scripts/model_usage.py --provider codex --mode current
python {baseDir}/scripts/model_usage.py --provider codex --mode all
python {baseDir}/scripts/model_usage.py --provider claude --mode all --format json --pretty

Current model logic

• Uses the most recent daily row with modelBreakdowns.
• Picks the model with the highest cost in that row.
• Falls back to the last entry in modelsUsed when breakdowns are missing.
• Override with --model <name> when you need a specific model.

Inputs

• Default: runs codexbar cost --format json --provider <codex|claude>.
• File or stdin:

codexbar cost --provider codex --format json > /tmp/cost.json
python {baseDir}/scripts/model_usage.py --input /tmp/cost.json --mode all
cat /tmp/cost.json | python {baseDir}/scripts/model_usage.py --input - --mode current

Output

• Text (default) or JSON (--format json --pretty).
• Values are cost-only per model; tokens are not split by model in CodexBar output.

• Read references/codexbar-cli.md for CLI flags and cost JSON fields.
