What are pre-trained models?

Frozen pasta from AI giants—trained on trillions of words, ready for your tweaks. No from-scratch nonsense.

Fine-tuning vs RAG: which is better?

Fine-tune for style/behavior. RAG for fresh facts. Prompts for everything else. RAG wins most real-world battles.

Prototypes, general tasks, tight budgets. It's fast—but finicky.

Grab that bag of frozen pasta. It's your pre-trained model. Heat it wrong, and you're eating mush. Welcome to AI's kitchen.

Pre-trained models are your cheap, ready base—don't reinvent the wheel. 𝕏
Prompt first, fine-tune only for behavior, RAG for knowledge. 𝕏
RAG will eclipse fine-tuning as the enterprise default, just like dynamic linking beat custom compiles. 𝕏
