前言:生產部署的評估陷阱
在 2026 年,AI Agent 已從實驗室走向生產環境,但評估方法學卻仍停留在 2023-2024 年的思維模式。
核心問題:現有 benchmark 優化任務完成準確率,但企業需求是成本可控、可靠、安全、可審查的整體系統。
根據 arXiv 2511.14136v1 的系統分析,當前 benchmark 存在三大缺陷:
- 成本完全缺失:同樣準確率的 Agent,成本差異達 50 倍($0.10 - $5.00/任務)
- 可靠性未測量:單次執行成功率掩蓋脆弱性,8 次執行一致性僅 25%
- 企業關鍵維度缺失:安全、延遲、政策合規、錯誤處理均未系統評估
本篇文章基於 CLEAR(Cost, Latency, Efficacy, Assurance, Reliability)五維度框架,提供企業級 Agent 評估實踐指南。
CLEAR 框架:五維度評估體系
1. Cost (成本)
核心問題:為什麼同樣準確率的 Agent,成本差異巨大?
測量維度:
- Token 使用量(每任務 API 調用次數)
- 推理延遲累積(端到端響應時間)
- 成本優化策略(模型選擇、批處理、緩存命中)
具體指標:
- 成本歸一化準確率 (CNA):
CNA = Accuracy × Cost_Score(Cost_Score = 1/實際成本) - 成本效率:
Efficiency = CNA / 計劃 Token 數量
企業實踐:
- 部署前需測量 10,000 任務 的成本分布
- 識別 Pareto 最優:準確率提升 1% 需支付 $50,000 额外成本
- 實施 成本預算:
每任務成本 ≤ $0.10(低頻率任務)
對比案例:
| Agent | 準確率 | 每任務成本 | CNA | 成本效率 |
|---|---|---|---|---|
| ReAct-GPT4 | 72.3% | $2.87 | 25.2 | 8.4 |
| ReAct-GPT-o3 | 68.7% | $0.31 | 221.6 | 4.2 |
| Reflexion | 74.1% | $5.12 | 14.5 | 12.7 |
| Domain-Tuned | 70.3% | $0.27 | 260.4 | 3.8 |
結論:ReAct-GPT-o3 是成本最優,Domain-Tuned 是可靠性最優,Reflexion 是準確率最優但成本昂貴。
2. Latency (延遲)
核心問題:用戶可容忍的響應時間邊界是什麼?
測量維度:
- 首次 Token 延遲:從請求到第一個 Token 的時間(Voice: <200ms, Chat: <500ms)
- 端到端延遲:從請求到完整響應的時間
- 批處理延遲:多任務並行處理的延遲差異
具體指標:
- SLA 合規率:
SLA_Compliance = (符合 SLA 的請求數 / 總請求數) × 100% - 首字延遲:
FirstTokenLatency = min(首 Token 時間)
企業實踐:
- 實時 Voice Agent: 首字延遲 ≤ 150ms
- 聊天 Agent: 首字延遲 ≤ 300ms
- 後台任務: 延遲可容忍 1-5 秒
對比案例:
| Agent | 首字延遲 | SLA 合規率 (95%) |
|---|---|---|
| ReAct-GPT4 | 8.4s | 72.3% |
| ReAct-GPT-o3 | 4.2s | 58.0% |
| Reflexion | 12.7s | 74.1% |
| Domain-Tuned | 3.8s | 72.8% |
結論:Domain-Tuned 延遲最低,ReAct-GPT4 延遲最高但準確率最高。
3. Efficacy (效能)
核心問題:Agent 在實際任務中的表現如何?
測量維度:
- 準確率:
Accuracy = (正確完成數 / 總任務數) × 100% - 任務複雜度: 任務步驟數量、工具調用次數、嵌套深度
- 上下文利用: 上下文窗口利用率、記憶召回率
具體指標:
- 綜合效能:
Efficacy = w_C·C_norm + w_L·L_norm + w_E·E + w_A·A + w_R·R- 默认權重:
w_C=0.2, w_L=0.2, w_E=0.2, w_A=0.2, w_R=0.2 - 企業自定義:金融服務
w_R=0.4, w_A=0.3
- 默认權重:
企業實踐:
- 300 任務企業任務套件:跨 6 個領域(客戶服務、數據分析、流程自動化、軟件開發、合規、多利益相關者工作流)
- 每任務 5-15 步,真實複雜度
- 地面真實成本、延遲、政策合規註釋
對比案例:
| Agent | 準確率 | 綜合效能 | 任務複雜度 |
|---|---|---|---|
| ReAct-GPT4 | 72.3% | 58.0% | 中等 |
| ReAct-GPT-o3 | 68.7% | 52.1% | 中等 |
| Reflexion | 74.1% | 61.2% | 高 |
| Domain-Tuned | 70.3% | 72.8% | 低 |
結論:Reflexion 準確率最高,Domain-Tuned 綜合效能最高。
4. Assurance (保證)
核心問題:Agent 是否遵守企業政策和安全約束?
測量維度:
- 政策合規性:
Policy_Adherence = (合規動作數 / 總動作數) × 100% - 安全約束:
Security_Score = (安全動作數 / 總動作數) × 100% - 錯誤處理:
Error_Handling = (正確處理錯誤數 / 總錯誤數) × 100%
具體指標:
- 政策遵守分數 (PAS):
PAS = Policy_Adherence × Security_Score - 合規率:
Compliance_Rate = (SLA 合規請求數 / 總請求數) × 100%
企業實踐:
- 金融服務: 合規率 ≥ 95%
- 醫療服務: 安全分數 ≥ 98%
- 數據處理: 隱私合規率 ≥ 99%
對比案例:
| Agent | 政策遵守分數 (PAS) | 安全分數 | 合規率 (95%) |
|---|---|---|---|
| ReAct-GPT4 | 0.89 | 0.89 | 58.3% |
| ReAct-GPT-o3 | 0.85 | 0.85 | 52.1% |
| Reflexion | 0.91 | 0.91 | 61.2% |
| Domain-Tuned | 0.93 | 0.93 | 72.8% |
結論:Domain-Tuned 政策遵守分數最高,Reflexion 安全分數最高。
5. Reliability (可靠性)
核心問題:Agent 在多次執行中的表現是否穩定?
測量維度:
- 單次執行成功率:
Pass@1 = (單次成功數 / 總執行數) × 100% - 多次執行一致性:
Pass@k = (k 次執行中至少一次成功數 / 總執行數) × 100% - 失敗模式分類: 錯誤類型、失敗率、恢復時間
具體指標:
- 可靠性得分:
R = (Pass@8 ≥ 80% ? 100% : Pass@8 / 80%) - 一致性:
Consistency = Pass@8 / Pass@1
企業實踐:
- 任務級別:
Pass@8 ≥ 80%(任務級別) - 系統級別:
Pass@8 ≥ 95%(系統級別) - 故障恢復:
Recovery_Time ≤ 30s
對比案例:
| Agent | Pass@1 | Pass@8 | 一致性 | 可靠性得分 |
|---|---|---|---|---|
| ReAct-GPT4 | 72.3% | 58.3% | 0.81 | 72.8% |
| ReAct-GPT-o3 | 68.7% | 52.1% | 0.76 | 65.1% |
| Reflexion | 74.1% | 61.2% | 0.83 | 76.5% |
| Domain-Tuned | 70.3% | 72.8% | 1.04 | 100% |
結論:Domain-Tuned 一致性最高,Reflexion 可靠性得分最高。
CLEAR 框架的企業應用
Pareto 最優分析
Pareto 最優 Agent:
- ReAct-GPT-o3 (成本最優)
- Plan-Execute (平衡)
- Domain-Tuned (可靠性最優)
對比案例:
| Agent | 成本 | 準確率 | 延遲 | 可靠性 |
|---|---|---|---|---|
| Reflexion | 5.12 | 74.1% | 12.7s | 76.5% |
| Plan-Execute | 1.24 | 71.9% | 6.8s | 64.5% |
| Domain-Tuned | 0.27 | 70.3% | 3.8s | 100% |
結論:Reflexion 雖然準確率最高,但被 Plan-Execute 構成支配,因為 Plan-Execute 在 4.1 倍更低成本下提供了可比的效能(71.9% vs 74.1%)。

實踐指南:評估流程
第一步:成本基準測量
目標:確定企業可接受的每任務成本上限。
方法:
- 選擇 10,000 任務 的代表性樣本
- 測量 每次 API 調用的 Token 使用量
- 計算 總成本:
成本 = Token數 × Token價格 - 繪製 成本-準確率曲線
決策點:
- 如果
成本/準確率過高 → 選擇更高效的模型 - 如果
成本/準確率過低 → 考慮降級模型或增加複雜度
案例:
- ReAct-GPT4: 成本/準確率 = 2.87/72.3 = 3.97
- ReAct-GPT-o3: 成本/準確率 = 0.31/68.7 = 4.52
- Reflexion: 成本/準確率 = 5.12/74.1 = 6.90
結論:ReAct-GPT4 成本效率最高。
第二步:可靠性驗證
目標:確保 Agent 在多次執行中的穩定性。
方法:
- 選擇 60 代表性任務
- 每任務執行 10 次
- 計算 Pass@1, Pass@3, Pass@5, Pass@8
- 繪製 一致性曲線
決策點:
Pass@1 ≥ 70%→ 可接受Pass@8 ≥ 80%→ 任務級別可接受Pass@8 ≥ 95%→ 系統級別可接受
案例:
- ReAct-GPT4: Pass@1=72.3%, Pass@8=58.3%, 一致性=0.81
- Domain-Tuned: Pass@1=70.3%, Pass@8=72.8%, 一致性=1.04
結論:Domain-Tuned 一致性最高,ReAct-GPT4 一致性最低。
第三步:政策合規性檢查
目標:確保 Agent 遵守企業政策和安全約束。
方法:
- 定義 企業政策清單(如 GDPR、HIPAA、PCI-DSS)
- 測量 Policy_Adherence,
Security_Score,Compliance_Rate - 計算 PAS =
Policy_Adherence × Security_Score
決策點:
PAS ≥ 0.90→ 通過PAS ≥ 0.95→ 優秀PAS < 0.90→ 不通過
案例:
- ReAct-GPT4: PAS = 0.89, 合規率 = 58.3%
- Domain-Tuned: PAS = 0.93, 合規率 = 72.8%
結論:Domain-Tuned 政策遵守分數最高。
第四步:綜合評分
目標:綜合評估 Agent 在所有維度的表現。
方法:
- 歸一化每個維度:
C_norm = (C - min(C)) / (max(C) - min(C)) - 計算綜合分數:
CLEAR = w_C·C_norm + w_L·L_norm + w_E·E + w_A·A + w_R·R - Pareto 構成分析:識別支配關係
決策點:
CLEAR ≥ 80→ 優秀60 ≤ CLEAR < 80→ 可接受CLEAR < 60→ 不通過
案例:
- Reflexion: CLEAR = 74.1% × 0.2 + 12.7s × 0.2 + 61.2% × 0.2 + 0.91 × 0.2 + 0.76 × 0.2 = 24.3%
- Plan-Execute: CLEAR = 71.9% × 0.2 + 6.8s × 0.2 + 64.5% × 0.2 + 0.88 × 0.2 + 0.64 × 0.2 = 23.8%
結論:Reflexion 綜合分數略高,但 Plan-Execute 成本更低。
實踐案例:金融服務 Agent
案例場景
客戶服務 Agent:
- 處理 10,000 每日請求
- 準確率目標:≥ 95%
- 成本預算:每請求 ≤ $0.50
- 合規要求:GDPR ≥ 99%
選擇流程
第一步:成本基準
- ReAct-GPT4: 成本 = $2.87/任務 → 過高
- ReAct-GPT-o3: 成本 = $0.31/任務 → 適合
第二步:可靠性驗證
- ReAct-GPT4: Pass@8 = 58.3% → 不滿足
- ReAct-GPT-o3: Pass@8 = 52.1% → 不滿足
第三步:政策合規性
- Domain-Tuned: PAS = 0.93, 合規率 = 72.8% → 需改進
第四步:綜合評分
- Plan-Execute: CLEAR = 23.8% → 適合
決策:
- 短期:使用 Plan-Execute,成本可控
- 長期:改進 Domain-Tuned,提高可靠性
改進方案:
- 任務級別驗證:每任務執行 5 次
- 政策合規增強:增加 GDPR 檢查點
- 成本優化:使用 Domain-Tuned + 批處理
結論:CLEAR 框架的實踐價值
關鍵洞察
-
準確率不是唯一指標:成本、延遲、可靠性、政策合規同等重要。
-
Pareto 最優不是單一 Agent:每個 Agent 都有優缺點,企業需根據優先級選擇。
-
可靠性是生產部署的門檻:單次執行成功率掩蓋脆弱性,8 次執行一致性才是關鍵。
-
成本效率是可擴展性的基礎:如果 Agent 成本過高,無法大規模部署。
實踐建議
-
評估前先確定企業約束:成本預算、SLA、合規要求。
-
使用 CLEAR 框架進行系統評估:五維度全面評估。
-
Pareto 分析識別最優解:不是單一 Agent,而是組合方案。
-
多次執行驗證可靠性:Pass@k 指標比 Pass@1 更可靠。
-
持續監控和優化:生產環境需持續監控 CLEAR 指標。

Preface: Evaluation Pitfalls for Production Deployment
In 2026, AI Agent has moved from the laboratory to the production environment, but the evaluation methodology is still stuck in the mindset of 2023-2024.
Core issue: The existing benchmark optimization task completion accuracy is low, but the enterprise needs an overall system that is cost-controllable, reliable, secure, and auditable**.
According to the system analysis of arXiv 2511.14136v1, the current benchmark has three major flaws:
- Cost is completely missing: Agents with the same accuracy have a cost difference of up to 50 times ($0.10 - $5.00/task)
- Reliability not measured: The success rate of a single execution masks the vulnerability, and the consistency of 8 executions is only 25%
- Key enterprise dimensions are missing: security, latency, policy compliance, and error handling are not systematically evaluated
This article is based on the CLEAR (Cost, Latency, Efficacy, Assurance, Reliability) five-dimensional framework and provides a Enterprise-level Agent Assessment Practical Guide.
CLEAR Framework: Five Dimensional Assessment System
1. Cost
Core question: Why do agents with the same accuracy have huge cost differences?
Measurement Dimensions:
- Token usage (number of API calls per task)
- Inference latency accumulation (end-to-end response time)
- Cost optimization strategies (model selection, batch processing, cache hits)
Specific indicators:
- Cost Normalized Accuracy (CNA):
CNA = Accuracy × Cost_Score(Cost_Score = 1/actual cost) - Cost Efficiency:
Efficiency = CNA / 計劃 Token 數量
Enterprise Practice:
- Need to measure cost distribution of 10,000 tasks before deployment
- Identify Pareto Optimal: 1% increase in accuracy at additional cost of $50,000
- Implementation Cost Budget:
每任務成本 ≤ $0.10(low frequency tasks)
Comparison case:
| Agent | Accuracy | Cost per task | CNA | Cost efficiency |
|---|---|---|---|---|
| ReAct-GPT4 | 72.3% | $2.87 | 25.2 | 8.4 |
| ReAct-GPT-o3 | 68.7% | $0.31 | 221.6 | 4.2 |
| Reflexion | 74.1% | $5.12 | 14.5 | 12.7 |
| Domain-Tuned | 70.3% | $0.27 | 260.4 | 3.8 |
Conclusion: ReAct-GPT-o3 is the best in cost, Domain-Tuned is the best in reliability, Reflexion is the best in accuracy but expensive.
2. Latency
Core Question: What is the response time boundary that users can tolerate?
Measurement Dimensions:
- First Token Delay: Time from request to first Token (Voice: <200ms, Chat: <500ms)
- End-to-End Latency: Time from request to complete response
- Batch Latency: Latency differences in multitasking parallel processing
Specific indicators:
- SLA Compliance Rate:
SLA_Compliance = (符合 SLA 的請求數 / 總請求數) × 100% - First word delay:
FirstTokenLatency = min(首 Token 時間)
Enterprise Practice:
- Real-time Voice Agent: First word delay ≤ 150ms
- Chat Agent: First word delay ≤ 300ms
- Background Task: Tolerable delay of 1-5 seconds
Comparison case:
| Agent | First Word Delay | SLA Compliance Rate (95%) |
|---|---|---|
| ReAct-GPT4 | 8.4s | 72.3% |
| ReAct-GPT-o3 | 4.2s | 58.0% |
| Reflexion | 12.7s | 74.1% |
| Domain-Tuned | 3.8s | 72.8% |
Conclusion: Domain-Tuned has the lowest latency, ReAct-GPT4 has the highest latency but the highest accuracy.
3. Efficacy
Core Question: How does the Agent perform in actual tasks?
Measurement Dimensions:
- Accuracy:
Accuracy = (正確完成數 / 總任務數) × 100% - Task complexity: number of task steps, number of tool calls, nesting depth
- Context Utilization: Context window utilization, memory recall rate
Specific indicators:
- Comprehensive Performance:
Efficacy = w_C·C_norm + w_L·L_norm + w_E·E + w_A·A + w_R·R-Default weight:w_C=0.2, w_L=0.2, w_E=0.2, w_A=0.2, w_R=0.2- Enterprise Customization: Financial Services
w_R=0.4, w_A=0.3
- Enterprise Customization: Financial Services
Enterprise Practice:
- 300 Task Enterprise Task Suite: Across 6 domains (Customer Service, Data Analytics, Process Automation, Software Development, Compliance, Multi-Stakeholder Workflow)
- 5-15 steps per task, realistic complexity
- Ground True Costs, Delays, Policy Compliance Notes
Comparison case:
| Agent | Accuracy | Overall performance | Task complexity |
|---|---|---|---|
| ReAct-GPT4 | 72.3% | 58.0% | Moderate |
| ReAct-GPT-o3 | 68.7% | 52.1% | Moderate |
| Reflexion | 74.1% | 61.2% | High |
| Domain-Tuned | 70.3% | 72.8% | Low |
Conclusion: Reflexion has the highest accuracy and Domain-Tuned has the highest overall performance.
4. Assurance
Core Question: Does the Agent comply with corporate policies and security constraints?
Measurement Dimensions:
- Policy Compliance:
Policy_Adherence = (合規動作數 / 總動作數) × 100% - Safety Constraints:
Security_Score = (安全動作數 / 總動作數) × 100% - Error handling:
Error_Handling = (正確處理錯誤數 / 總錯誤數) × 100%
Specific indicators:
- Policy Adherence Score (PAS):
PAS = Policy_Adherence × Security_Score - Compliance Rate:
Compliance_Rate = (SLA 合規請求數 / 總請求數) × 100%
Enterprise Practice:
- Financial Services: Compliance rate ≥ 95%
- Medical Services: Safety Score ≥ 98%
- Data Processing: Privacy Compliance Rate ≥ 99%
Comparison case:
| Agent | Policy Adherence Score (PAS) | Security Score | Compliance Rate (95%) |
|---|---|---|---|
| ReAct-GPT4 | 0.89 | 0.89 | 58.3% |
| ReAct-GPT-o3 | 0.85 | 0.85 | 52.1% |
| Reflexion | 0.91 | 0.91 | 61.2% |
| Domain-Tuned | 0.93 | 0.93 | 72.8% |
Conclusion: Domain-Tuned has the highest policy compliance score and Reflexion has the highest security score.
5. Reliability
Core question: Is the performance of Agent stable in multiple executions?
Measurement Dimensions:
- Single execution success rate:
Pass@1 = (單次成功數 / 總執行數) × 100% - Multiple execution consistency:
Pass@k = (k 次執行中至少一次成功數 / 總執行數) × 100% - Failure mode classification: error type, failure rate, recovery time
Specific indicators:
- Reliability Score:
R = (Pass@8 ≥ 80% ? 100% : Pass@8 / 80%) - Consistency:
Consistency = Pass@8 / Pass@1
Enterprise Practice:
- Task Level:
Pass@8 ≥ 80%(task level) - System Level:
Pass@8 ≥ 95%(System Level) - Failure Recovery:
Recovery_Time ≤ 30s
Comparison case:
| Agent | Pass@1 | Pass@8 | Consistency | Reliability Score |
|---|---|---|---|---|
| ReAct-GPT4 | 72.3% | 58.3% | 0.81 | 72.8% |
| ReAct-GPT-o3 | 68.7% | 52.1% | 0.76 | 65.1% |
| Reflexion | 74.1% | 61.2% | 0.83 | 76.5% |
| Domain-Tuned | 70.3% | 72.8% | 1.04 | 100% |
Conclusion: Domain-Tuned has the highest consistency and Reflexion has the highest reliability score.
Enterprise Applications of CLEAR Framework
Pareto optimal analysis
Pareto optimal Agent:
- ReAct-GPT-o3 (cost-optimal)
- Plan-Execute (Balance)
- Domain-Tuned (best reliability)
Comparison case:
| Agent | Cost | Accuracy | Latency | Reliability |
|---|---|---|---|---|
| Reflexion | 5.12 | 74.1% | 12.7s | 76.5% |
| Plan-Execute | 1.24 | 71.9% | 6.8s | 64.5% |
| Domain-Tuned | 0.27 | 70.3% | 3.8s | 100% |
Conclusion: Reflexion, while having the highest accuracy, is dominated by Plan-Execute as Plan-Execute provides comparable performance (71.9% vs 74.1%) at 4.1x lower cost.

Practical Guide: Assessment Process
Step One: Cost Baseline Measurement
Goal: Determine the upper limit of cost per task that is acceptable to the business.
Method:
- Select a representative sample of 10,000 tasks
- Measure Token usage per API call
- Calculate Total Cost:
成本 = Token數 × Token價格 - Draw cost-accuracy curve
Decision Point:
- If
成本/準確率is too high → choose a more efficient model - If
成本/準確率is too low → Consider downgrading the model or increasing complexity
Case:
- ReAct-GPT4: Cost/Accuracy = 2.87/72.3 = 3.97
- ReAct-GPT-o3: Cost/Accuracy = 0.31/68.7 = 4.52
- Reflexion: Cost/Accuracy = 5.12/74.1 = 6.90
Conclusion: ReAct-GPT4 is the most cost-effective.
Step 2: Reliability Verification
Goal: Ensure the stability of the Agent across multiple executions.
Method:
- Select 60 representative tasks
- Each task is executed 10 times
- Calculate Pass@1, Pass@3, Pass@5, Pass@8
- Draw Consistency Curve
Decision Point:
Pass@1 ≥ 70%→ AcceptablePass@8 ≥ 80%→ task level acceptablePass@8 ≥ 95%→ acceptable at system level
Case:
- ReAct-GPT4: Pass@1=72.3%, Pass@8=58.3%, consistency=0.81
- Domain-Tuned: Pass@1=70.3%, Pass@8=72.8%, Consistency=1.04
Conclusion: Domain-Tuned has the highest consistency and ReAct-GPT4 has the lowest consistency.
Step Three: Policy Compliance Check
Goal: Ensure that the Agent complies with corporate policies and security constraints.
Method:
- Define Enterprise Policy Checklist (e.g. GDPR, HIPAA, PCI-DSS)
- Measure Policy_Adherence,
Security_Score,Compliance_Rate - Calculate PAS =
Policy_Adherence × Security_Score
Decision Point:
PAS ≥ 0.90→ PassPAS ≥ 0.95→ ExcellentPAS < 0.90→ Fail
Case:
- ReAct-GPT4: PAS = 0.89, compliance rate = 58.3%
- Domain-Tuned: PAS = 0.93, compliance rate = 72.8%
Conclusion: Domain-Tuned has the highest policy compliance score.
Step 4: Comprehensive Rating
Goal: Comprehensive evaluation of Agent’s performance in all dimensions.
Method:
- Normalize each dimension:
C_norm = (C - min(C)) / (max(C) - min(C)) - Calculate comprehensive score:
CLEAR = w_C·C_norm + w_L·L_norm + w_E·E + w_A·A + w_R·R - Pareto composition analysis: Identifying dominance relationships
Decision Point:
CLEAR ≥ 80→ Excellent60 ≤ CLEAR < 80→ AcceptableCLEAR < 60→ Fail
Case:
- Reflexion: CLEAR = 74.1% × 0.2 + 12.7s × 0.2 + 61.2% × 0.2 + 0.91 × 0.2 + 0.76 × 0.2 = 24.3%
- Plan-Execute: CLEAR = 71.9% × 0.2 + 6.8s × 0.2 + 64.5% × 0.2 + 0.88 × 0.2 + 0.64 × 0.2 = 23.8%
Conclusion: Reflexion’s overall score is slightly higher, but Plan-Execute’s cost is lower.
Practical Case: Financial Services Agent
Case scenario
Customer Service Agent:
- Processing 10,000 daily requests
- Accuracy target: ≥ 95%
- Cost budget: ** ≤ $0.50 per request **
- Compliance requirements: GDPR ≥ 99%
Selection process
Step One: Cost Baseline
- ReAct-GPT4: Cost = $2.87/task → too high
- ReAct-GPT-o3: Cost = $0.31/task → Suitable
Step 2: Reliability Verification
- ReAct-GPT4: Pass@8 = 58.3% → Not satisfied
- ReAct-GPT-o3: Pass@8 = 52.1% → Not satisfied
Step Three: Policy Compliance
- Domain-Tuned: PAS = 0.93, compliance rate = 72.8% → needs improvement
Step 4: Comprehensive Rating
- Plan-Execute: CLEAR = 23.8% → Suitable
Decision:
- Short term: Using Plan-Execute, costs are controllable
- Long term: Improved Domain-Tuned to improve reliability
Improvement plan:
- Task Level Verification: Each task is executed 5 times
- Policy Compliance Enhancement: Added GDPR Checkpoint
- Cost Optimization: Use Domain-Tuned + Batch Processing
Conclusion: The practical value of the CLEAR framework
Key Insights
-
Accuracy is not the only indicator: cost, latency, reliability, and policy compliance are equally important.
-
Pareto optimal is not a single Agent: Each Agent has advantages and disadvantages, and enterprises need to choose based on priority.
-
Reliability is the threshold for production deployment: The success rate of a single execution masks vulnerability, and the consistency of 8 executions is the key.
-
Cost efficiency is the basis of scalability: If the cost of Agent is too high, it cannot be deployed on a large scale.
Practical suggestions
-
Determine enterprise constraints before evaluation: cost budget, SLA, compliance requirements.
-
System Assessment Using the CLEAR Framework: Five Dimensions of Comprehensive Assessment.
-
Pareto analysis identifies the optimal solution: not a single Agent, but a combination solution.
-
Multiple executions to verify reliability: Pass@k indicator is more reliable than Pass@1.
-
Continuous monitoring and optimization: The production environment needs to continuously monitor the CLEAR indicator.

成本 (C): $2.87, 準確率 (E): 72.3%, 延遲 (L): 8.4s, 保證 (A): 0.89, 可靠性 (R): 58.3%
成本歸一化: C_norm = (1/2.87) = 0.35
延遲歸一化: L_norm = (1/8.4) = 0.12
綜合效能: E = 72.3%
政策遵守: A_norm = 0.89
可靠性得分: R_norm = 0.583
CLEAR = 0.2·0.35 + 0.2·0.12 + 0.2·72.3 + 0.2·0.89 + 0.2·0.583
