AI Engineers can be quite successful in this role without ever training anything

This is how they can succeed: 

1/ Leveraging pre-trained LLMs: Select and tune existing LLMs for specific tasks. Don't start from scratch 

2/ Prompt engineering: Craft effective prompts to optimize LLM performance without model modifications 

3/ Implement Modern AI Solution Architectures: Design systems like RAG to enhance LLMs with external knowledge 

Developers: The barrier to entry is lower than ever.  

Focus on the solution's VALUE and connect AI components like you were assembling Lego!
