Fine-tuning adapts pre-trained models to specific domains or tasks through specialized training. SeekrFlow automates dataset creation, manages training workflows, and deploys fine-tuned models as custom endpoints.

How fine-tuning works

The fine-tuning process adjusts model parameters by training on structured question-and-answer pairs. Models learn from examples that demonstrate desired behaviors, domain knowledge, and specific output patterns. The training produces specialized models with deeper expertise while retaining general capabilities from the base model.

​
When to use fine-tuning

Fine-tuning provides value when:
  • Working with proprietary or sensitive information not in base model training data.
  • Requiring specific output formats, styles, or tones.
  • Optimizing for tasks more easily demonstrated than described.
  • Improving accuracy on domain-specific terminology or concepts.
  • Reducing costs by using smaller specialized models.

​
Fine-tuning methods

SeekrFlow supports multiple fine-tuning approaches:
MethodDescriptionBest for
Instruction fine-tuningStandard approach that trains models on question-and-answer pairs aligned to task-specific instructions. Embeds domain knowledge directly into model parameters.Embedding proprietary knowledge, customizing behavior and tone, optimizing for demonstrated tasks
Context-grounded fine-tuningTraining approach that teaches models to access and retrieve information from external knowledge bases during inference. Maintains accuracy with frequently changing information.Dynamic information that requires real-time updates, maintaining current data without retraining
Reinforcement tuning (GRPO)Teaches the model to judge its own outputs using a reward function that scores generated responses against reference answers, rather than directly imitating target responses.Improving response quality, aligning outputs with brand voice, reducing unwanted behaviors
Preference tuning (DPO)Learns directly from comparisons between preferred and dispreferred responses, without requiring reference answers or reward functions.Aligning outputs with subjective quality criteria, organizational standards, human feedback

Most fine-tuning projects should:
1
Start with LoRA + instruction fine-tuning as the default approach.
2
Use context-grounded fine-tuning if information requires frequent updates.
3
Add reinforcement tuning or preference tuning as a refinement step if quality alignment is needed.
4
Consider full fine-tuning only after LoRA experiments show it’s necessary.
This progression balances training efficiency with model quality while minimizing upfront investment.

​
Low-rank adaptation (LoRA)

Low-rank adaptation (LoRA) is a parameter-efficient optimization technique that can be applied to any of the fine-tuning methods above. Rather than updating all model weights during training, LoRA trains small adapter modules, enabling faster training with lower compute costs while preserving base model knowledge. LoRA can be used with instruction fine-tuning, context-grounded fine-tuning, reinforcement tuning, or preference tuning to reduce resource requirements and speed up iteration cycles.

​
Vision language tuning

Vision language tuning extends fine-tuning to models that process both images and text. The training workflow is the same as text-only fine-tuning — the difference is in the input data and model selection. Currently, SeekrFlow supports instruction fine-tuning of vision-language models with the same SDK primitives as text-only training.

​
Dataset preparation

Fine-tuning requires structured training datasets with question-and-answer pairs. SeekrFlow’s data engine automates the creation of training-ready datasets from raw source files, generating examples that demonstrate desired model behaviors and domain knowledge. Learn more: AI-ready data

Model deployment

Fine-tuned models are deployed as custom model endpoints. Once active, fine-tuned models can be used in agents, inference workflows, or any application requiring specialized model behavior.
