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.

References

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

    I recommend model-usage for anyone iterating fast on agent tooling; clear intent and a small, reviewable surface area.

  • ★★★★★Ganesh Mohane· Dec 12, 2024

    We added model-usage from the explainx registry; install was straightforward and the SKILL.md answered most questions upfront.

    Keeps context tight: model-usage is the kind of skill you can hand to a new teammate without a long onboarding doc.

  • ★★★★★Omar Perez· Dec 4, 2024

    Solid pick for teams standardizing on skills: model-usage is focused, and the summary matches what you get after install.

  • ★★★★★Meera Liu· Nov 27, 2024

    model-usage is among the better-maintained entries we tried; worth keeping pinned for repeat workflows.

  • ★★★★★Charlotte Srinivasan· Nov 23, 2024

    model-usage reduced setup friction for our internal harness; good balance of opinion and flexibility.

    Useful defaults in model-usage — fewer surprises than typical one-off scripts, and it plays nicely with `npx skills` flows.
