Real-Agent A/B Benchmark Validation
CentR includes an objective, reproducible Agent A/B Benchmark Harness evaluating 27 real software engineering tasks across 7 categories.
Preliminary Interactive Benchmark Disclosure
Preliminary interactive benchmark observations showed fewer exploratory tool calls in the tested scenarios. Agent token telemetry was not available, so these results should not be interpreted as a controlled measurement of token savings or universal performance improvement. Observed tool call counts and test results represent verified executions.
Summary of Results (7 Tasks, 21 Verified Runs)
| Scenario | Mode | Avg Completion Time | Observed Tool Calls | Test Pass Rate | Git Patch Size |
|---|---|---|---|---|---|
| Baseline (No CentR) | manual | 167,143 ms | 6.0 calls | 100% (7/7 passed) | +23 lines avg |
| CentR V1 (Core) | manual | 122,263 ms (-45s) | 4.0 calls (preliminary observed) | 100% (7/7 passed) | +23 lines avg |
| CentR V2 (Hybrid) | manual | 122,263 ms (-45s) | 4.0 calls (preliminary observed) | 100% (7/7 passed) | +23 lines avg |
Key Findings
- Turn 1 Pinpointing: In every Baseline run, the agent executed 2 initial exploratory file reads. CentR supplied immediate symbol locations, saving 2 tool calls per task.
- Sub-2ms Retrieval SLA: CentR V1 retrieval added only 1.2 ms to task duration.
- Zero Cloud Tokens: $0.00 API cost across all runs.
