model-usage

利用 CodexBar CLI 的本地成本统计功能，针对 Codex 或 Claude 模型，按单个模型汇总使用情况，既可查看当前（最新）使用的模型，也可获得完整的模型使用明细。当您需要从 codexbar 获取模型级别的使用量或成本数据，或是希望从 codexbar 的成本 JSON 中提取可编程的单模型摘要时，此功能便能派上用场。

description: Use CodexBar CLI local cost usage to summarize per-model usage for Codex or Claude, including the current (most recent) model or a full model breakdown. Trigger when asked for model-level usage/cost data from codexbar, or when you need a scriptable per-model summary from codexbar cost JSON.

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.
bash
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:
bash
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.
