VELX – Proprietary Model Adaptation & Bring Your Own LLM (BYO-LLM)

Overview​

VELX provides enterprise-grade support for adapting large language models (LLMs) to proprietary codebases and enabling integration with customer-selected external models.

This module ensures that AI-powered modernization can operate with maximum contextual accuracy, security, and architectural flexibility while maintaining full enterprise control over data and model behavior.

1. Fine-Tuning on Proprietary Codebases

VELX supports secure fine-tuning of foundation models using customer-authorized proprietary code and documentation.

Fine-Tuning Objectives​

  • Improve code transformation accuracy
  • Adapt to organization-specific coding standards
  • Align with internal architectural conventions
  • Reflect domain-specific terminology
  • Capture proprietary framework patterns
  • Enhance test generation relevance
  • Improve modernization recommendations

Supported Approaches​

  • Full model fine-tuning (where permitted)
  • Parameter-efficient fine-tuning (PEFT)
  • Adapter-based tuning
  • Domain-specific instruction tuning
  • Reinforcement tuning using human feedback (optional)

Fine-tuning workflows are executed within customer-controlled environments.

2. Secure Data Handling During Model Adaptation

VELX enforces strict security controls during training and adaptation processes.

Security Controls​

  • Customer-authorized dataset boundaries
  • Air-gapped fine-tuning option
  • Encryption at rest and in transit
  • Isolated training environments
  • Dataset version tracking
  • Training artifact audit logs
  • Zero external data sharing

Customer code is never used for training without explicit contractual approval.

3. Bring Your Own LLM (BYO-LLM)

VELX supports integration with externally hosted or privately deployed language models.

Integration Capabilities​

  • Private model hosting within customer infrastructure
  • Integration with enterprise AI platforms
  • Model routing by task type
  • Multi-model orchestration
  • Secure API-based model invocation
  • On-premise inference endpoints
  • Hybrid cloud model deployment

Organizations can select models based on performance, compliance, cost, or regulatory requirements.

4. Model Routing & Task Specialization

VELX includes an intelligent model orchestration layer.

Routing Capabilities​

  • Task-based model selection (e.g., transformation vs. documentation)
  • Risk-based routing policies
  • Sensitive-data-aware routing
  • Performance-based fallback models
  • Cost-optimization routing strategies

This allows enterprises to combine:

  • Foundation models
  • Fine-tuned internal models
  • Specialized domain models
  • Smaller task-specific models

All routing decisions are auditable and policy-controlled.

5. Knowledge Augmentation with RAG

Even when using external or fine-tuned models, VELX augments responses using contextual retrieval.

Context Injection Sources​

  • Indexed proprietary code
  • Business rule repository
  • Architecture knowledge graph
  • Configuration files
  • Migration history artifacts

This ensures outputs remain grounded in the actual system state rather than relying solely on model memory.

6. Governance & Model Lifecycle Management

VELX provides governance over the entire model lifecycle.

Governance Controls​

  • Model versioning
  • Performance monitoring
  • Drift detection
  • Output quality metrics
  • Safety evaluation benchmarks
  • Controlled promotion of fine-tuned models
  • Rollback capability to previous model versions

All model changes follow enterprise approval workflows.

7. Compliance & Enterprise Readiness

VELX’s model adaptation framework supports regulated environments.

Compliance Features​

  • Audit logging of model interactions
  • Dataset lineage tracking
  • Reproducibility of fine-tuning runs
  • Policy-based access controls
  • Regional deployment constraints (where required)

This ensures AI modernization capabilities remain compliant with internal governance and regulatory standards.

Summary

The VELX Proprietary Model Adaptation & BYO-LLM module enables:

  • Secure fine-tuning on proprietary codebases
  • Flexible integration of external and private models
  • Multi-model orchestration and routing
  • Enterprise-grade governance and compliance controls
  • Context-grounded AI outputs through knowledge augmentation

By combining adaptable model architecture with strict security and governance controls, VELX ensures AI modernization workflows remain accurate, secure, and fully aligned with enterprise requirements.
