If science class explained everything with Midwest emo music, we would have a lot more people paying attention.

Nuclear power explained.
It’s just a fancy way to heat water and make electricity.

This is my parting gift for the year.

Arguably my best podcast listen all year. @Nairametrics’ Drinks & Mics wrapped the year with Mayokun Ajibade, SA to the CBN Gov on Financial Markets & Economic Policy.

His clarity reinforces why to bet on PBAT & 🇳🇬.

I strongly recommend.

Needed to add company knowledge to LLM.

Plan:
- Collect 5,000 company documents
- Convert to training format
- Fine-tune Llama 2 on SageMaker
- Deploy custom model

Started fine-tuning:
- Training time: 6 hours
- Cost: $450 for GPU instances
- Result: Model that knew company facts

But:
- Model hallucinated variations of facts
- Couldn't update without retraining
- New document? Retrain entire model
- Wrong information learned? Retrain entire model
- Each iteration: 6 hours + $450

Then tried RAG (Retrieval Augmented Generation):
- Embedded all documents with OpenAI
- Stored in pgvector (Postgres extension)
- Query flow:
- User asks question
- Find relevant documents (vector similarity search)
- Send documents + question to LLM
- LLM answers using provided context

RAG setup time: 2 hours
RAG cost: $0.02 per query (embedding + LLM)

RAG benefits:
- Update knowledge: Add/remove documents (seconds)
- Fix wrong info: Update document (seconds)
- No retraining needed
- Cite sources (know where answer came from)
- Works with any LLM

Fine-tuning benefits:
- Lower inference cost (no retrieval step)
- Faster responses
- Custom behavior/tone
- Works offline

When I'd use fine-tuning:
- Teaching model new task/format
- Changing model behavior/style
- High-volume inference (cost matters)
- Need offline deployment

When I'd use RAG:
- Adding knowledge that changes
- Need source citations
- Multiple knowledge domains
- Fast iteration needed

Start with RAG, not fine-tuning. Fine-tuning is for behavior, RAG is for knowledge.

You probably don't need custom model weights. You need a better prompt with the right context.
