LLM FINE-TUNING TECHNIQUES

A Systematic, Hybrid LLM Fine-Tuning Methodology

Curated for Your Specific Enterprise Use Cases

Generic LLMs are trained on billions of parameters across the entire internet. Therefore, a single approach to fine-tuning AI rarely creates the expected outcomes. We combine LLM fine-tuning techniques​, such as supervised learning for task-specific optimization, reinforcement learning from human feedback (RLHF) for quality and safety alignment, parameter-efficient fine-tuning for cost management, and domain-adaptive pre-training for deep industry knowledge. These hybrid LLM fine-tuning approaches enable our team to rewire the AI's neural pathways to align with your business objectives and act as a specialist.

Supervised Fine-Tuning (SFT)

Training LLMs on Specific Behaviors, Formats, or Domain Knowledge

Our team creates input-output or question-answer pairs with clear, correct responses to train LLMs on specific behaviors, formats, or domain knowledge. We can also systematically train your model using parameter-efficient methods (LoRA, QLoRA) or full fine-tuning based on your performance requirements and budget.

Best for:

  • Data extraction and classification tasks requiring high accuracy, like contract clause extraction, named entity recognition, and sentiment analysis
  • Domain-specific applications needing specialized terminology, like medical documentation, legal research, and financial analysis
  • Structured output generation, like report creation, form filling, and code generation, that follows specific patterns
  • Repetitive specialized tasks where consistency matters more than creativity, like document review, compliance checking, and quality control automation
RLHF (Reinforcement Learning from Human Feedback)

Aligning LLM models with Subjective Quality and Human Values

To help AI models identify and judge tone, appropriateness, safety, brand alignment, quality standards, etc., our experts rank multiple AI responses to the same prompt (marking which response is more helpful, safer, more appropriate.

Best for:

  • Customer-facing applications where quality is subjective, like support chatbots, advisory systems, and conversational agents
  • Safety-critical systems requiring alignment with human values, like content moderation, mental health support interfaces, and educational platforms
  • Brand-aligned content generation, like marketing copy, social media responses, and customer communications
  • Applications with competing objectives that require nuanced trade-offs, like being concise yet thorough, friendly yet professional, or helpful yet safe
DPO (Direct Preference Optimization)

For Simpler, Faster LLM Fine-Tuning without RLHF's Complexity

For low-stakes projects with tight timelines and budgets, we offer a simpler alternative to reinforcement learning from human feedback. Our team optimizes preferences directly by curating preference pairs (which response is better and why), so your model can be directly optimized without the need to train a reward model.

Best for:

  • Projects testing AI before full deployment, like pilot programs for new chatbots and proof-of-concept conversational tools
  • Time-sensitive launches with compressed development cycles, like seasonal campaign support tools and product launch assistants with fixed deadlines
  • Iterative development projects requiring frequent experimentation, like A/B testing brand voice implementations
  • Mid-complexity applications where RLHF would be overkill, like internal knowledge base assistants, departmental productivity tools, and specialized content generators
Constitutional AI

Fine-Tuning AI for Safety, Ethics, and Brand Values

Train an LLM to critique and revise its own outputs based on a written set of rules and values - a constitution. Our team creates a set of concrete, testable rules (based on enterprise values, safety requirements, behavioral standards, and edge cases) that your AI should follow, evaluates the responses, and monitors ongoing alignment with your constitution.

Best for:

  • Regulated Industries with compliance requirements, like healthcare, financial services, legal, and government
  • Brand-sensitive customer-facing applications, like customer service chatbots, marketing AI, and social media agents
  • Multi-stakeholder platforms with diverse safety needs, like social networks, marketplaces, and community forums
  • Enterprise AI with complex operational policies, like internal productivity tools, HR systems, and knowledge management systems

FAQ - Frequently Asked Questions

LLM Fine-Tuning Services

LLM fine-tuning is the process of taking a pre-trained foundation model (like GPT-4, Claude, or LLaMA) and training it further on specialized data to make it an expert in your specific domain or task. Instead of starting from scratch, we help you adapt an already-powerful AI to understand your industry terminology, follow your quality standards, and perform your exact workflows.

We curate a specialized dataset with examples of correct inputs and outputs, human-preference rankings, or constitutional principles, so the model can learn domain-specific terminology and formatting requirements and align with your quality standards. This targeted training is delivered through techniques such as supervised learning (teaching specific tasks), reinforcement learning from human feedback (aligning with preferences), or direct preference optimization (simpler, preference-based training), depending on your goals.

No one can guarantee zero hallucinations—it's an unsolved research problem. However, we can:

  • Significantly reduce hallucination rates through subject matter expert involvement in LLM fine-tuning
  • Implement confidence scoring and uncertainty communication
  • Use RAG to ground responses in real data
  • Train the model to acknowledge when it doesn't know
  • Red Team to find and fix problematic patterns

We offer data support for general AI model fine-tuning (i.e., for adapting any pre-trained model), which includes data annotation services (image, text, video labeling), AI data management & processing services (flipping or resizing images, creating “synthetic” data by rotating, zooming, or adjusting the contrast/brightness etc. in videos, removing noise like HTML tags or weird emojis from text), and evaluating model responses with the help of domain experts.

We can work with OpenAI (GPT), Google (Gemini), Anthropic (Claude), open-source models such as LLaMA (Meta), Mistral, and Falcon, and custom deployment environments.

We assess three key factors: knowledge requirements, task complexity, and output consistency needs. Complex enterprise systems often benefit from fine-tuned base behavior, RAG for knowledge access, and prompt engineering for request routing and output formatting.

  • Prompt engineering is most effective when the base model already has the necessary knowledge, and you simply need to structure queries effectively.
  • RAG (Retrieval-Augmented Generation) is useful when you need the model to access specific, up-to-date, or proprietary information that wasn't in its training data—such as internal documents, recent reports, or dynamic databases.
  • Fine-tuning is necessary when you need the model to fundamentally change its behavior, learn specialized terminology, adopt specific formatting patterns, or align with subjective quality standards that can't be achieved through prompts alone.

When the base model already understands your domain and task type, we recommend prompt engineering as a faster, more cost-effective alternative to fine-tuning. Our prompt engineering services focus on optimizing how you communicate with the model rather than retraining it. This includes designing structured prompts with clear instructions and examples, reformatting outputs to meet your exact specifications, implementing reasoning frameworks (such as chain-of-thought or step-by-step logic), and creating reusable prompt templates that better leverage the model's existing capabilities.

Our RAG services focus on connecting language models to your knowledge sources in real-time rather than embedding static information through training. This includes architecting retrieval systems that query your internal documents, databases, or knowledge bases; implementing semantic search to find the most relevant information for each query; optimizing chunking and indexing strategies for accurate retrieval; designing hybrid approaches that combine fine-tuned models with RAG for both behavioral consistency and current information access; and building evaluation frameworks to ensure retrieved context actually improves response quality and accuracy.
