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
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
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
/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.
