Make LLMs Learn Your Niche – With InstructLAB

Ever found yourself questioning an AI’s response to a topic you know well, thinking, “If only I could make it more accurate for my needs…”? Now you can! With InstructLAB. It is a groundbreaking open-source initiative by IBM and RedHat, with which you can fine-tune Large Language Models (LLMs) to specialize in your domain—no machine learning expertise required. 

The Challenge with Generalized LLMs 

LLMs excel at general tasks but falter with niche, domain-specific questions. Fine-tuning traditionally demands downloading the model, using extensive resources, human-annotated data, and proprietary tools, making it costly and inaccessible to many. 

Enter InstructLAB: A Collaborative Solution

InstructLAB redefines LLM customization by offering a user-friendly Command Line Interface (CLI) for training models with a method called Large-scale Alignment for ChatBots (LAB). This ensures precision, scalability, and collaboration without burning through resources.

 

Here’s how InstructLAB empowers your AI journey: 

 

1. Taxonomy-Driven Data Curation 

InstructLAB organizes training data into a hierarchical structure called taxonomy: 

  • Knowledge: Domain-specific content (e.g., finance, healthcare).
  • Foundational Skills: Core abilities like coding and math.
  • Compositional Skills: Complex, blended tasks such as analytical reporting.  

This ensures a model learns every layer of expertise systematically—like teaching a chef the recipe, ingredient properties, and cooking techniques. 
To add knowledge, you create YAML files (e.g., qna.yaml) with questions, answers, and attributions, all neatly categorized. 
When new files are added to any directory in taxonomy, and we run the command ilab taxonomy diff, it will prompt the valid statement. 

2. Synthetic Data Generation 

Seed examples from the taxonomy are amplified into large-scale synthetic datasets. This boosts training diversity and fills gaps in the model’s understanding without costly manual annotation. 

Eg. The model generates antonyms for different words, based on the way the seed examples given to it. 

3. Multi-Phase Training Framework 

Training happens in two phases: 

  • Knowledge Tuning: Models first master basics using short, clear datasets.
  • Skills Tuning: Advanced, compositional skills are layered on, with replay buffers preventing earlier lessons from being forgotten. 

This systematic approach ensures stability and precision, making your LLM a domain expert. 

InstructLAB isn’t just a tool—it’s a paradigm shift. By decentralizing LLM training, it fosters collaboration, reduces costs, and ensures high-quality domain-specific models. Whether you’re scaling your AI or tackling niche challenges, the future of tailored AI starts here. Ready to make LLMs your domain experts? Start with InstructLAB.
