Using LLMs in Your Business: What’s the Right Path?
Discover how to apply LLMs in your business with strategies like RAG, Fine-Tuning, and Prompt Engineering, aligned with your level of digital maturity.
The adoption of Large Language Models (LLMs) is redefining how businesses create, automate, and use intelligence. But there is a big difference between simply using an AI like ChatGPT and truly adapting it to your company’s reality.
In this article, we’ll explore five practical ways to use LLMs, from general-purpose solutions to highly specialized models. We’ll also look at how these approaches connect to your organization’s level of digital maturity.
1. Online Chats: Fast, but Generic
Platforms like ChatGPT, Gemini, Claude, and others operate with billions of parameters, making them extremely powerful for working with natural language and multimodal content (text, images, videos, and audio).
Advantages:
- Available immediately
- Low barrier to entry
- Ideal for brainstorming, summaries, and idea generation
Limitations:
- They don’t understand your business context
- They aren’t safe for sensitive data
- Risk of “hallucinations” (incorrect answers that appear true)
? Recommended for companies at the beginner stage of digital maturity, which are still exploring what AI can do.
2. Prompt Engineering: Efficiency with Creativity
With good prompt engineering practices, you can guide AI to deliver more accurate responses tailored to your company’s reality, even without training it directly on your context.
Advantages:
- Aligns AI behavior with specific needs
- No fine-tuning or advanced development required
- Low technical barrier (with the right command of language)
Limitations:
- Still depends on a general-purpose model
- Quality depends heavily on the user’s skill
- Can be inconsistent on complex tasks
? Ideal for companies at the “engaged” stage of digital maturity, looking to improve processes without having to develop in-house solutions.
3. RAG – Retrieval-Augmented Generation: AI with Access to Your Knowledge
The RAG model combines the power of an LLM with a document database, allowing AI to retrieve real information (from PDFs, internal websites, and structured databases) before generating a response.
Advantages:
- Generates more accurate, fact-based responses
- Lets you control the information sources
- Scales well for customer service, knowledge bases, and intelligent customer support systems
Limitations:
- Requires data sources to be structured
- May have higher latency
- Requires integration with data infrastructure
? Recommended for companies at the “optimizer” stage of digital maturity, which already have structured data and want to scale customer service or training.
4. Fine-Tuning: AI That Learns from Your Company
Fine-tuning lets you adapt an existing model using data specific to your business, such as previous customer interactions, brand language, or internal processes.
Advantages:
- Creates a model that is truly aligned with your business
- Highly customizable
- Fewer errors and greater efficiency
Limitations:
- Requires high-quality data curation
- Technically demanding and more costly
- Requires ongoing capacity for updates
? Essential for companies at the “innovator” stage, looking to build competitive advantages with custom AI.
5. Specialized Models: AI with a PhD in Your Field
Some models are trained to work in specific fields such as mathematics, finance, medicine, or Google Cloud, with deep expertise in a technical domain.
Advantages:
- Highly accurate results
- Optimized for complex tasks
- Reduced risks in sensitive areas
Limitations:
- Limited to the domain they were trained on
- May be inflexible outside their scope
- Licensing can be expensive
? Recommended for companies with high digital maturity, operating in regulated fields or with highly specific performance and compliance needs.
How to Align This Approach with the Digital Maturity Model
Choosing between these approaches isn’t just a technical decision. It’s directly connected to your company’s level of digital maturity. Using the CDE (Continuous Digital Evolution) framework, you can see how they line up:
| Maturity Level | Most Common LLM Strategy |
|---|---|
| Beginner | Online Chats |
| Engaged | Prompt Engineering |
| Optimizer | RAG |
| Innovator | Fine-Tuning / Specialized Models |
The key is to align your company’s technological capabilities with AI’s potential to deliver results. It’s not about rushing to apply just any AI tool. It’s about understanding where you are, what data you have available, and what your business goals are.
Conclusion: The Right Choice Evolves with You
There is no single, definitive approach. LLMs are like turbines for digital growth, but they need to be calibrated to the right context.
? Do you just want to speed up tasks or create a real competitive advantage?
? Does your business already have the data and infrastructure to take the next step?
? Are you measuring AI ROI in practice?
The AI journey isn’t about following a trend. It’s about strategy.
