SFT vs RLHF: How to Choose the Best AI Training Method | 2025

In 2025, 67% of enterprises worldwide have integrated Large Language Models (LLMs) into their operations, reflecting a decisive shift toward AI-driven transformation. However, according to Gartner, despite widespread adoption, only about 45% of organizations with high AI maturity sustain AI projects for three years or more, underscoring ongoing challenges in achieving domain-specific accuracy and adaptability essential for long-term success.

This discrepancy highlights that success in AI deployment hinges not on raw computational power but on how effectively organizations fine-tune these models for their unique business contexts.

Among the fine-tuning techniques, Supervised Fine-Tuning (SFT) and Reinforcement Learning from Human Feedback (RLHF) stand out as pivotal methods for adapting Large Language Models (LLMs) to meet domain-specific demands.

SFT delivers reliable, high-precision outputs when trained on curated labeled data, making it ideal for well-defined tasks. RLHF, by incorporating iterative human feedback, enhances model alignment with complex, evolving user needs but often demands greater resources and may reduce output diversity.

In this article, we’ll dive into the comprehensive analysis of SFT vs RLHF, exploring their strengths, limitations, and strategic applications while offering insights as well as best practices to help enterprises strategically select and apply fine-tuning methods that optimize multimodal AI performance.

The Rise of Fine-Tuning in Large-Language Models

While generic LLMs provide broad language understanding, they often fall short when deployed directly in specialized enterprise contexts such as precise code generation, customer support automation, or healthcare text analysis. Fine-tuning is essential to bridge this gap, aligning models with human expectations and business goals by customizing their behavior on domain-specific datasets.

For organizations looking to understand the fundamental concepts behind model customization, our comprehensive guide on data labeling for fine-tuning LLMs provides essential insights into what fine-tuning entails and how fine-tuned models differ from their base counterparts.

The benefits of fine-tuning include:

• Deep integration of specialized knowledge: Fine-tuning “embeds” domain-specific information directly into the model’s weights, improving performance on targeted tasks.
• Customization of style and format: Models can be trained to produce outputs in specific formats or tones, such as generating JSON responses or adhering to regulatory language.
• Enhanced handling of complex generation tasks: Fine-tuning improves the model’s ability to follow multi-step instructions or generate creative, rule-based content.

As enterprises adopt multimodal AI combining language, vision, and other data types, fine-tuning remains key to delivering tailored, high-performance AI solutions that meet evolving business demands.

Supervised Fine-Tuning (SFT): Precision through Structured Learning

Supervised Fine-Tuning (SFT) is a structured learning process that adapts a pre-trained Large Language Model (LLM) to perform specific tasks by training it on a high-quality, labeled dataset containing input-output pairs. This process refines the model’s parameters to generate precise, context-aware responses aligned with the target application.

How SFT works

Step 1: Dataset preparation

• Data collection: Gather raw data relevant to the specific domain or task. The dataset size can vary from hundreds to tens of thousands of examples depending on complexity and model size.
• Data structuring: Format the data into structured pairs, typically in JSON Lines (JSONL) format, where each entry contains an input prompt and the corresponding desired output.
• Quality assurance: Ensure data accuracy, consistency, diversity, and minimize biases to avoid negatively impacting model behavior.

Step 2: Tokenization

• Convert text inputs and outputs into tokens (the model’s basic units of understanding) using a tokenizer compatible with the pre-trained model. This step enables efficient processing and learning.

Step 3: Fine-tuning training loop

• Next token prediction objective: SFT uses the same training objective as pre-training, predicting the next token in a sequence, but focuses only on the output portion of the input-output pairs.
• Forward pass: The model processes the input tokens and generates predicted tokens for the output sequence.
• Loss calculation: Compute the difference (loss) between the predicted tokens and the actual tokens from the labeled dataset.
• Backpropagation: Adjust the model’s weights to minimize this loss using gradient descent and optimization algorithms.
• Iteration: Repeat this process over multiple epochs, gradually improving the model’s task-specific performance.

Step 4: Evaluation and validation

• Use a separate validation dataset to monitor the model’s accuracy and prevent overfitting. Hyperparameters such as learning rate, batch size, and number of epochs are tuned based on validation results.

Step 5: Deployment

• Once the model achieves satisfactory accuracy and generalization, it is deployed for real-world applications such as chatbots, content generation, or domain-specific assistants.

Best practices for SFT data preparation

Effective data preparation is the foundation of successful Supervised Fine-Tuning. The quality, representativeness, and structure of your dataset directly impact the model’s accuracy, generalization, and robustness. Below are the key best practices to follow:

1. Collect high-quality, relevant data

• Cleanliness: Remove duplicates, inconsistencies, irrelevant or noisy entries to avoid confusing the model.
• Relevance: Ensure data examples closely match the real-world inputs the model will encounter in deployment.
• Representativeness: Include diverse examples covering all important variations, edge cases, and scenarios to avoid bias and improve generalization.
• Balanced Dataset: Avoid skewed distributions that overrepresent certain classes or outcomes, which can lead to biased predictions.

2. Use proper labeling and annotation

• Clear guidelines: Define precise annotation instructions to ensure consistency across annotators.
• Expert review: Involve domain experts for labeling specialized data (e.g., medical, legal) to maintain accuracy.
• Quality control: Regularly audit labeled data to detect and correct errors or ambiguities.

3. Format data correctly

• Use supported formats such as JSON Lines (JSONL) where each line contains an input-output pair.
• Ensure inputs and outputs are clearly separated and correctly tokenized if needed.
• For multimodal data (text, images, audio), maintain consistent and compatible formatting.

4. Optimize dataset size and diversity

• Start with a minimum viable dataset (e.g., 100–1,000 examples) and scale up as needed.
• Prioritize quality over quantity; smaller, well-curated datasets outperform large noisy ones.
• Use data augmentation techniques (paraphrasing, synonym replacement, synthetic examples) to increase diversity without excessive labeling cost.

5. Split data for training, validation, and testing

• Maintain strict separation between training, validation, and test sets to avoid data leakage.
• Use validation data during training to monitor performance and prevent overfitting.
• Test on unseen data to evaluate real-world generalization.

6. Monitor and prevent overfitting

• Regularly evaluate model metrics (accuracy, loss, BLEU/ROUGE for generation tasks) on validation data.
• Adjust hyperparameters (learning rate, batch size, epochs) based on validation feedback.

7. Leverage transfer learning techniques

• Freeze lower layers of the pre-trained model that capture general knowledge to preserve foundational capabilities.
• Fine-tune only task-specific layers to reduce training time and avoid catastrophic forgetting.

8. Continuous iteration and improvement

• Fine-tuning is an iterative process; use feedback from model performance and real-world testing to refine datasets.
• Incorporate new data and edge cases discovered during deployment to keep the model updated and robust.

Reinforcement Learning from Human Feedback (RLHF): Aligning AI with Human Preferences

Reinforcement Learning from Human Feedback (RLHF) is an advanced machine learning technique that enhances pre-trained Large Language Models (LLMs) by incorporating human judgments into the training process. Unlike Supervised Fine-Tuning (SFT), which relies on fixed labeled datasets, RLHF uses human feedback to train a reward model that guides the AI to generate outputs more aligned with complex, nuanced human values and preferences.

How RLHF works

Step 1: Collect human feedback

• Human evaluators review model-generated outputs and rank or rate them according to quality, relevance, or other criteria.
• This feedback captures complex preferences that are difficult to encode explicitly.

Step 2: Train a reward model

• Using the human feedback data, a reward model is trained in a supervised manner to predict the human scores for any given output.
• This reward model effectively quantifies human preferences into a learnable function.

Step 3: Reinforcement learning optimization

• The LLM is fine-tuned using reinforcement learning algorithms (e.g., Proximal Policy Optimization) that optimize the model’s policy to maximize the reward predicted by the reward model.
• The model iteratively improves by generating outputs that receive higher reward scores, effectively aligning with human expectations.

Step 4: Evaluation and iteration

• The model’s outputs are continuously evaluated by humans and the reward model to ensure alignment and prevent undesirable behaviors.
• The process iterates, refining both the reward model and the LLM’s policy.

Step 5: Deployment

• The RLHF-tuned model is deployed in real-world applications such as conversational agents, content generation, or recommendation systems, delivering outputs that better reflect human values and preferences.

RLHF training process summary

1. Human feedback collection	Gather rankings or ratings on model outputs from human evaluators.	Captures nuanced, context-specific human preferences.
2. Reward model training	Train a supervised model to predict human feedback scores.	Translates subjective human judgments into a quantitative reward function.
3. Reinforcement learning	Optimize the LLM to maximize the reward model’s output using RL algorithms.	Aligns model behavior with complex human values and goals.
4. Evaluation & iteration	Continuously assess and refine model outputs with human input and reward model feedback.	Ensures ongoing improvement and safety of AI responses.
5. Deployment	Release the aligned model for production use in applications requiring nuanced understanding.	Provides AI outputs that are more accurate, helpful, and aligned with user expectations.

Key benefits of RLHF

• Alignment with human values: RLHF enables models to better understand and reflect complex human preferences, including ethical and social norms.
• Improved output quality: Models trained with RLHF generate more coherent, contextually appropriate, and user-friendly responses than those trained solely with supervised learning.
• Handling ambiguity and subjectivity: RLHF excels in tasks where “correct” answers are subjective or hard to define algorithmically, such as humor, politeness, or creativity.
• Reduction of harmful content: By incorporating human feedback, RLHF helps models avoid generating biased, toxic, or inappropriate outputs.
• Continuous improvement: The iterative nature of RLHF allows models to evolve and adapt as human preferences and societal standards change.

Limitation of RLHF

• Cost and scalability of human feedback: Collecting high-quality human annotations is expensive and time-consuming.
• Bias in feedback: If the human feedback is not diverse or representative, the model may learn unintended biases.
• Complexity of training: RLHF requires sophisticated infrastructure and expertise to implement reinforcement learning algorithms effectively.
• Potential for reward model misalignment: Imperfect reward models can lead to unintended behaviors if they do not fully capture human preferences.

4. Augment and diversify data

• Use data augmentation techniques such as paraphrasing prompts or generating synthetic examples to increase diversity without excessive annotation costs.
• Include edge cases and challenging scenarios to improve model robustness and safety.

5. Structure data for efficient training

• Format data clearly separating prompts, model outputs, and human preference labels.
• Use standardized formats (e.g., JSONL) to facilitate seamless integration with training pipelines.

6. Iterative feedback and continuous improvement

• RLHF is an iterative process: continuously collect new human feedback on model outputs to refine the reward model and policy.
• Incorporate real-world usage data and edge cases discovered during deployment to keep the model aligned and up-to-date.

7. Ethical considerations and bias mitigation

• Monitor for and mitigate biases in human feedback to prevent reinforcing harmful stereotypes or unfair behaviors.
• Maintain transparency and ethical oversight throughout data collection and model training.
