Corporations generally do not dream of building their own private LLMs because of several significant blockers that make such an initiative seem unrealistic, costly, or unnecessary.
1. Cost and Infrastructure
- Hardware Costs: Training an LLM requires high-performance GPUs, TPUs, or custom AI chips, which are expensive and in high demand.
- Cloud vs. On-Prem Considerations: Running on-prem requires massive server infrastructure, while cloud-based training has recurring costs that escalate with model complexity and size.
- Energy Consumption: Training and running large models require enormous amounts of power, making it a sustainability and budgetary concern.
2. Talent and Expertise
- AI/ML Expertise: Building an LLM requires experts in deep learning, natural language processing (NLP), distributed computing, and optimization—talent that is expensive and in short supply.
- Data Scientists & Engineers: Continuous improvement, fine-tuning, and deployment demand a skilled team, which most companies don’t have in-house.
3. Data Challenges
- Access to High-Quality Data: Training an LLM requires massive, diverse, and well-labeled datasets. Many corporations don’t have enough proprietary text data to train a model from scratch.
- Data Privacy & Compliance: Handling sensitive corporate data comes with regulatory constraints (GDPR, CCPA, HIPAA, etc.), making proprietary training complex.
- Data Curation & Cleaning: Extracting value from corporate data requires heavy preprocessing to remove noise, inconsistencies, and legal risks (e.g., confidential or personally identifiable information).
4. Security & Compliance Risks
- Intellectual Property Risks: Training models on proprietary data risks leaking trade secrets if the model is not carefully controlled.
- Hallucination & Liability: LLMs can generate misleading, incorrect, or legally problematic outputs, making them risky for critical decision-making.
- Regulatory Uncertainty: Emerging AI regulations could impose stricter rules on corporate AI training and deployment.
5. Operational Complexity
- Fine-Tuning & Maintenance: LLMs require continuous fine-tuning to remain useful, relevant, and aligned with corporate policies.
- Inference Costs: Even running a model at scale (inferencing) incurs costs—especially when dealing with thousands of queries per second.
- Model Updates & Versioning: Keeping models updated with new knowledge is non-trivial and resource-intensive.
6. Unclear ROI
- Competing with Off-the-Shelf Models: Why build an LLM from scratch when you can fine-tune existing models from OpenAI, Anthropic, Mistral, or Meta at a fraction of the cost?
- Limited Business Justification: Many corporations don’t have problems that justify a custom LLM versus a well-tuned SaaS solution.
- Cost-Benefit Tradeoff: The investment in a private LLM often outweighs the benefits for most companies.
How 3DI Addresses These Blockers
Rather than building an LLM from scratch, corporations can leverage 3DI’s leave-behind LLMs, which:
- Avoid the need for extensive hardware investments by training on pre-structured corporate data.
- Eliminate hallucinations and data leakage by operating within the corporate perimeter.
- Enhance classification, attribution, and validation (RCAV) for superior performance.
- Ensure regulatory compliance and security by keeping data in-house while offering the benefits of LLM-based automation.
To build their own corporate-specific LLMs, corporations need a better, pre-structured approach to leveraging AI—one that makes use of their existing data in a way that’s cost-effective, scalable, and aligned with business needs. That’s exactly where 3DI transforms the equation.
