Methods

Fine-tuning approaches

LoRA (Low-Rank Adaptation)

Efficient fine-tuning by training small adapter layers while freezing base model weights.

95% less memoryFast trainingEasy switchingMultiple adapters

Best for: Most use cases, quick iteration

QLoRA (Quantized LoRA)

Combine 4-bit quantization with LoRA for fine-tuning large models on consumer hardware.

Data Preparation

From raw data to training-ready

01

Data Collection

Gather domain-specific examples, documents, and interaction logs relevant to your use case.

02

Data Cleaning

Remove duplicates, fix formatting issues, and filter low-quality or irrelevant examples.

03

Format Conversion

Convert data to instruction-response pairs, chat format, or completion format as needed.

04

Quality Validation

Review samples, validate labels, and ensure data represents desired model behavior.

Use Cases

What you can achieve with fine-tuning

Industry-Specific Language

Train models on legal, medical, financial, or technical terminology for accurate domain communication.

Example: Medical AI that understands clinical notes and ICD codes

Company Knowledge

Fine-tune on internal documents, processes, and product information for accurate company-specific responses.

Example: Support bot trained on your product documentation

Brand Voice & Style

Train models to match your brand's communication style, tone, and formatting preferences.

Example: Marketing AI that writes in your brand voice

Task-Specific Performance

Optimize for specific tasks like classification, extraction, summarization, or code generation.

Example: Contract clause extraction with 99% accuracy
