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.

CodexBar ships CLI builds for macOS and Linux. When codexbar is on PATH, the skill reads local usage directly; the bundled Python summarizer also accepts exported CodexBar JSON through --input anywhere Python is available.

Quick start

Fetch cost JSON via CodexBar CLI or pass a JSON file.

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
