Qwen Data Source (Experimental)

Qwen support is experimental. Expect breaking changes while both ccusage and Qwen Code continue to evolve.

ccusage can read Qwen Code chat JSONL files as one of its supported local data sources, using the same focused and all-source report views as the rest of ccusage.

Focused Views

bunx (Recommended)

bunx ccusage qwen --help

npx

npx ccusage@latest qwen --help

pnpm

pnpm dlx ccusage qwen --help

Data Source

The CLI reads Qwen chat JSONL files from QWEN_DATA_DIR (defaults to ~/.qwen). QWEN_DATA_DIR can be one directory or a comma-separated list of directories.

QWEN_DATA_DIR="$HOME/.qwen,/backup/qwen" ccusage qwen daily

~/.qwen/
└── projects/
    └── {project}/
        └── chats/
            └── *.jsonl

Report Views

Focused view	Description	See also
ccusage qwen daily	Aggregate usage by date	Daily Usage
ccusage qwen monthly	Aggregate usage by month	Monthly Usage
ccusage qwen session	Group usage by Qwen session	Session Usage

These views support --json for structured output, --compact for narrow terminals, and --offline for cached pricing data.

What Gets Calculated

• Token usage - Qwen assistant rows provide input and output token counts through usageMetadata.
• Reasoning tokens - thoughtsTokenCount is included in totalTokens and priced as output tokens when pricing data is available.
• Cache tokens - cachedContentTokenCount is treated as cache read tokens. Qwen logs do not currently expose cache creation tokens.
• Pricing - Costs are calculated from LiteLLM pricing data using the raw model name and Qwen provider-prefixed candidates.

Environment Variables

Variable	Description
QWEN_DATA_DIR	Override the root directory, or comma-separated root directories, containing Qwen data
LOG_LEVEL	Adjust verbosity (0 silent ... 5 trace)

Troubleshooting

No Qwen usage data found

Ensure the data directory exists at ~/.qwen/projects/{project}/chats/. Set QWEN_DATA_DIR if your Qwen data lives elsewhere or in multiple archive roots.

Costs showing as $0.00

If a model is not in LiteLLM's database, the cost will be $0.00. Open an issue to request alias support.
