Beyond the Hype: A Realistic Look at Large Language Models • Jodie Burchell • GOTO 2024
Explore the reality behind LLMs with data scientist Jodie Burchell. Learn key advances, limitations, and best practices for implementing LLMs in production environments.
-
Large Language Models (LLMs) are not showing signs of Artificial General Intelligence (AGI) - they are sophisticated pattern matching systems with specific limitations
-
LLMs are best suited for natural language processing tasks like text classification, summarization, translation, and question answering within their training domain
-
The success of modern LLMs is built on three key advances:
- Development of transformer architecture
- Availability of massive training datasets (Common Crawl)
- GPU acceleration through CUDA
-
Retrieval Augmented Generation (RAG) helps overcome LLM limitations by:
- Augmenting responses with external knowledge
- Reducing hallucinations
- Enabling domain-specific applications
-
Key challenges when deploying LLMs:
- Choosing the right model for specific use cases
- Proper tuning and configuration
- Managing computing requirements
- Handling sensitive data
-
LLM performance should be evaluated based on:
- Ability to generalize to new problems
- Performance within intended problem domain
- Specific benchmarks for target tasks
-
Common misconceptions about LLMs:
- They don’t truly understand context
- They can’t create new knowledge
- They’re not replacing human intelligence
- They require quality training data
-
Best practices for LLM implementation:
- Define clear scope and use cases
- Measure performance carefully
- Use domain-specific fine-tuning when needed
- Implement proper validation and testing
-
Technical considerations for RAG:
- Chunk size and overlap
- Embedding model selection
- Number of retrieved chunks
- Vector database configuration
