About this course

Architecture decisions are cost decisions. Whether you choose a larger model or a smaller one, RAG or fine-tuning, embeddings or full context — each choice locks in a cost shape that compounds over time. This course gives you the frameworks and data to make those decisions with clearer economic tradeoffs, not intuition alone.

What you will learn

  • How to compare LLMs across cost, latency, and output quality for a specific workload
  • How OpenAI and Anthropic pricing models differ and when a premium model is worth the cost
  • When to use embeddings vs full context, and the cost implications of each approach
  • How to choose between RAG, fine-tuning, and full-context for knowledge-heavy workloads

How to choose the right LLM for your workload

Compare cost, latency, and output quality in a way that supports real engineering and product tradeoffs.

28 min

OpenAI vs Anthropic pricing

Use provider and model pricing differences to decide when a premium model is worth the cost.

38 min

Embedding model options and tradeoffs

Compare embedding approaches and cost implications when retrieval is part of the production stack.

410 min

Embeddings vs full context cost efficiency

Choose when to retrieve vs stuff more context. Decision rules and cost shapes for small vs large knowledge bases.
