+# Benchmark Cost Calculation
+
+This directory contains benchmark data and automated cost calculation reports for the AMACI operator.
+
+## Files
+
+- **`cost.json`**: Configuration file containing base costs for different machine types and scales
+- **`report.json`**: Auto-generated JSON report with detailed cost calculations (generated by CI/CD)
+- **`report.md`**: Auto-generated human-readable Markdown report (generated by CI/CD)
+- **`bench-12c-128G-Bare-metal.md`**: Manual benchmark results for 12c-128G bare metal configuration
+
+## Automated Cost Calculation
+
+The cost calculation is automatically triggered by:
+
+1. **On Commit**: When `benchmark/cost.json` is modified and pushed/PR'd
+2. **Daily Schedule**: Every day at 00:00 Beijing Time (16:00 UTC)
+3. **Manual Trigger**: Can be manually triggered via GitHub Actions workflow
+
+### How It Works
+
+The calculation script (`scripts/calculate-benchmark.ts`):
+
+1. Reads cost configuration from `cost.json`
+2. Fetches current DORA price from CoinGecko API (ID: `dora-factory-2`)
+3. Calculates costs using the formula:
+   ```
+   Final USD Cost = Base Cost × Idle Sharing Multiplier
+   DORA Amount = Final USD Cost ÷ DORA Price
+   ```
+4. Compares with previous report to show price changes
+5. Generates both JSON and Markdown reports
+6. Commits the reports back to the repository
+
+### Cost Configuration Format
+
+```json
+{
+  "machineTypes": {
+    "12c-128G-Bare-metal": {
+      "currentTallyCostUsd": {
+        "2-1-1-5": 0.02,
+        "4-2-2-25": 1
+      },
+      "idleSharingMultiplier": 10
+    }
+  }
+}
+```
+
+- **currentTallyCostUsd**: Base cost in USD for each scale
+- **idleSharingMultiplier**: Multiplier to account for idle machine sharing
+
+### Running Manually
+
+To generate a report manually:
+
+```bash
+# No need to build, tsx runs TypeScript directly
+npm run benchmark:calculate
+```
+
+The generated reports will be saved to:
+- `benchmark/report.json`
+- `benchmark/report.md`
+
+### Report Format
+
+The generated report includes:
+
+- **Timestamp**: When the report was generated
+- **DORA Price**: Current price and 24h change from CoinGecko
+- **Cost Breakdown**: For each machine type and scale:
+  - Base cost in USD
+  - Multiplier applied
+  - Final cost in USD
+  - Equivalent DORA amount
+  - Change indicator (compared to previous report)
+- **Price Comparison**: How DORA price changed since last report
+
+### GitHub Actions Workflow
+
+The workflow is defined in `.github/workflows/benchmark-report.yml` and:
+
+1. Checks out the repository
+2. Sets up Node.js environment
+3. Installs dependencies (including `tsx` for running TypeScript)
+4. Runs the cost calculation directly using `tsx`
+5. Commits and pushes the reports if changed
+6. On pull requests, posts the report as a comment
+
+## Notes
+
+- The DORA price is fetched in real-time from CoinGecko API
+- If the API fails, it will retry 3 times, then fall back to cached price
+- Reports are automatically committed with `[skip ci]` to avoid triggering infinite loops
+- The daily scheduled run ensures reports stay up-to-date with DORA price fluctuations
