GISE Governance Framework

Effective governance is essential for successful AI system deployment. The GISE governance framework provides structured approaches to model management, prompt library control, security implementation, and operational oversight for both LLM-for-Dev and LLM-in-Product tracks.

Governance Architecture Overview​

Model Governance​

Model Registry & Lifecycle Management​

The model registry serves as the single source of truth for all AI models used across your organization.

Registry Components:

  • Model Metadata: Version, training data, performance metrics, licensing
  • Performance Benchmarks: Accuracy, latency, cost per inference
  • Approval Workflows: Review and approval processes for model deployment
  • Deprecation Policies: Sunset procedures for outdated models
# Example Model Registry Entry

      allowed_use_cases: ["customer-support", "content-generation"]
      restricted_use_cases: ["financial-advice", "medical-diagnosis"]
      max_concurrent_requests: 1000

Performance Monitoring Framework​

Continuous monitoring ensures models maintain expected performance levels in production.

Key Metrics:

  • Accuracy Metrics: Response relevance, factual correctness, hallucination rates
  • Performance Metrics: Latency percentiles, throughput, availability
  • Cost Metrics: Token usage, API costs, infrastructure expenses
  • Business Metrics: User satisfaction, task completion rates, conversion impact

Compliance Management​

Ensure AI systems meet regulatory and organizational requirements.

Compliance Areas:

  • Data Privacy: GDPR, CCPA, industry-specific regulations
  • Security Standards: SOC2, ISO 27001, industry frameworks
  • Audit Requirements: Logging, traceability, evidence collection
  • Ethical AI: Bias detection, fairness metrics, transparency

Prompt Library Management​

Version-Controlled Prompt Library​

Treat prompts as code with proper software engineering practices.

Prompt Testing Framework​

Automated validation ensures prompt effectiveness and safety.

interface PromptTest {
  id: string;
  promptId: string;
  testCase: {
    input: string;
    expectedOutputPattern: RegExp | string;
    context?: any;
  };
  validation: {
    accuracy: number;
    latency: number;
    safety: boolean;
    cost: number;
  };
}

class PromptTestingFramework {
  async runPromptTests(promptId: string): Promise<TestResults> {
    const prompt = await this.promptLibrary.getPrompt(promptId);
    const testCases = await this.getTestCases(promptId);
    
    const results: TestResult[] = [];
    
    for (const testCase of testCases) {
      const result = await this.runSingleTest(prompt, testCase);
      results.push(result);
    }
    
    return {
      promptId,
      testRunId: this.generateTestRunId(),
      timestamp: new Date(),
      totalTests: testCases.length,
      passedTests: results.filter(r => r.passed).length,
      averageLatency: this.calculateAverageLatency(results),
      averageCost: this.calculateAverageCost(results),
      safetyViolations: results.filter(r => !r.safetyCheck).length,
      detailedResults: results
    };
  }
  
  private async runSingleTest(prompt: Prompt, testCase: PromptTest): Promise<TestResult> {
    const startTime = Date.now();
    
    try {
      const response = await this.llmService.complete({
        prompt: prompt.content,
        input: testCase.testCase.input,
        context: testCase.testCase.context
      });
      
      const endTime = Date.now();
      
      return {
        testId: testCase.id,
        passed: this.validateResponse(response, testCase.testCase.expectedOutputPattern),
        response: response,
        latency: endTime - startTime,
        cost: this.calculateCost(response),
        safetyCheck: await this.runSafetyCheck(response),
        timestamp: new Date()
      };
      
    } catch (error) {
      return {
        testId: testCase.id,
        passed: false,
        error: error.message,
        latency: Date.now() - startTime,
        cost: 0,
        safetyCheck: false,
        timestamp: new Date()
      };
    }
  }
}

    new ProfanityFilter(),
    new LengthValidator(),
    new FormatValidator()
  ];
  
  async validateInput(userInput: string, context: RequestContext): Promise<ValidationResult> {
    const results: ValidatorResult[] = [];
    
    for (const validator of this.validators) {
      const result = await validator.validate(userInput, context);
      results.push(result);
      
      // Fail fast on critical violations
      if (result.severity === 'critical' && !result.passed) {
        return {
          passed: false,
          reason: result.reason,
          severity: result.severity,
          sanitizedInput: null,
          blockRequest: true
        };
      }
    }
    
    // Apply sanitization if needed
    const sanitizedInput = await this.applySanitization(userInput, results);
    
    return {
      passed: true,
      sanitizedInput,
      warnings: results.filter(r => r.severity === 'warning'),
      blockRequest: false
    };
  }
  
  private async applySanitization(input: string, results: ValidatorResult[]): Promise<string> {
    let sanitized = input;
    
    // Apply PII masking
    const piiResults = results.filter(r => r.validatorType === 'pii');
    for (const result of piiResults) {
      sanitized = result.sanitizeFunction(sanitized);
    }
    
    // Apply profanity filtering
    const profanityResults = results.filter(r => r.validatorType === 'profanity');
    for (const result of profanityResults) {

    ];
    
    const criticalIssues = checks.filter(c => c.severity === 'critical' && !c.passed);
    const warnings = checks.filter(c => c.severity === 'warning' && !c.passed);
    
    return {
      overallRating: this.calculateOverallRating(checks),
      criticalIssues: criticalIssues,
      warnings: warnings,
      shouldBlock: criticalIssues.length > 0,
      suggestedActions: this.generateSuggestedActions(checks),
      metadata: {
        timestamp: new Date(),
        contextId: context.id,
        modelUsed: context.model
      }
    };
  }
  
  private async checkHallucination(output: string, context: GenerationContext): Promise<OutputCheck> {
    // Check for factual accuracy against retrieved context
    if (context.retrievedSources) {
      const factualConsistency = await this.verifyFactualConsistency(output, context.retrievedSources);
      return {
        checkType: 'hallucination',
        passed: factualConsistency.score > 0.8,
        score: factualConsistency.score,
        severity: factualConsistency.score < 0.6 ? 'critical' : 'warning',
        details: factualConsistency.details
      };
    }
    
    // Use general hallucination detection
    const hallucinationScore = await this.detectHallucination(output);
    return {
      checkType: 'hallucination',
      passed: hallucinationScore < 0.3,
      score: 1 - hallucinationScore,
      severity: hallucinationScore > 0.7 ? 'critical' : 'warning',
