1. How much domain-specific training data do you have?

📚

Large dataset (10K+ curated examples)

I have substantial labeled data in my domain

📄

Small dataset (100–1K examples)

Limited but high-quality examples available

❌

Minimal / no training data

I mostly have documents, FAQs, or knowledge base

2. How often does your knowledge base change?

🔄

Frequently (daily or more)

Data changes often, retraining would be constant

📅

Occasionally (weekly/monthly)

Periodic updates, manageable retraining

🗿

Rarely (stable domain)

Knowledge is relatively static

2. Is your domain highly specialized or generic?

🎯

Highly specialized

Medical, legal, technical — needs precise domain expertise

🌐

Somewhat generic

General knowledge with some domain flavor

2. Do you have documents/knowledge-base to reference?

📚

Yes, substantial documents

FAQs, manuals, wikis, reports, etc.

❓

Not really

Limited reference material available

3. What’s your latency requirement?

⚡

Real-time (<500ms)

Fast responses critical for user experience

🐢

Can tolerate slower (1-5s)

Batch processing or async workflows OK

✅ Recommendation: RAG (Retrieval-Augmented Generation)

Go with RAG 🔍

RAG is ideal for your use case. It retrieves relevant documents at generation time, ensuring answers are grounded in up-to-date knowledge without retraining. It’s cost-effective, explainable (source attribution), and handles knowledge updates seamlessly.

✅ Pros

Always current — no retraining needed
Source attribution & explainability
Lower upfront cost
Easy to update knowledge

⚠️ Watch out

Retrieval quality is critical
Higher latency than pure generation
Context window limits retrieval volume

RAGBest tools: LangChain, LlamaIndex, Haystack, AWS Bedrock KB

✅ Recommendation: Fine-Tuning

Go with Fine-Tuning 🧪

Fine-tuning is the right choice when you have a large, stable dataset and need the model to deeply internalize domain patterns, terminology, or style. It produces faster, more consistent outputs without retrieval overhead.

✅ Pros

Fast inference — no retrieval step
Deep domain expertise baked in
Consistent style and terminology
Lower per-query cost at scale

⚠️ Watch out

Expensive to train and retrain
Knowledge becomes stale
Risk of catastrophic forgetting
Needs quality training data

Fine-TuningBest tools: OpenAI FT API, Axolotl, Unsloth, HuggingFace TRL

✅ Recommendation: Hybrid Approach

Go Hybrid 🔀

A hybrid approach combines fine-tuning for domain style/terminology with RAG for up-to-date knowledge retrieval. This gives you the best of both worlds: fast, domain-aware responses grounded in current information.

✅ Pros

Domain expertise + current knowledge
Optimized latency with cached retrieval
Most flexible architecture

⚠️ Watch out

More complex to implement
Higher initial development cost
Requires orchestration layer

HybridBest tools: LangGraph, custom orchestration, cached retrieval

✅ Recommendation: Few-Shot Prompting

Go with Few-Shot 🎯

With limited data, few-shot prompting is your best bet. Include 3-5 carefully chosen examples in your prompt to guide the model. It’s the fastest to implement, requires no training, and works well for focused tasks.

✅ Pros

Zero training cost
Instant to deploy and iterate
Works with any base model
Easy to A/B test examples

⚠️ Watch out

Consumes context window
Quality depends on example selection
Not ideal for complex domain shifts

Few-ShotBest tools: Dynamic example selection, example banks, DSPy

document.getElementById(from).classList.remove(‚active‘);

target.classList.add(‚active‘);

}

document.querySelectorAll(‚.tree-node,.result‘).forEach(el=>el.classList.remove(‚active‘));
document.getElementById(‚q1‘).classList.add(‚active‘);

}
