INSIGHT

Understanding Tokens in AI Models

  • Tokens represent less than one word each and are the building blocks AI models process.
  • Using tokens instead of characters speeds up generation but changes how models "see" language compared to humans.
INSIGHT

Importance of Long Context Windows

  • Long context windows enable supplying extensive relevant knowledge to models and overcome limitations of pre-trained memory.
  • Larger context means better recall and coverage, reducing memory-based errors like hallucinations.
ADVICE

Synergy of Long Context and RAG

  • Combine long context with RAG to improve recall and relevance of retrieved information.
  • Use longer contexts to include more chunks, enhancing model responses where latency allows.
