Five takeaways (source text)
| # | Takeaway | Detail | Taught in |
|---|---|---|---|
| 1 | Tokens are the unit of input, output, and cost. | Think and budget in tokens rather than words, since that is what the API meters and the context window measures. | Lesson 2 |
| 2 | The context window is a fixed token budget that holds the whole request at once. | An oversized input errors before generation, while hitting the ceiling mid-generation returns truncated output with a model_context_window_exceeded stop reason, so managing history is the application's job. | Lesson 2 |
| 3 | Sampling makes generation non-deterministic. | The same prompt can return different wording on each run, so testing on exact text is unreliable. This is what evals are built for. | Lesson 2 |
| 4 | Model choice and reasoning mode are separate, composable levers. | Pick the smallest model and the simplest reasoning and prompting that meet your eval and add capability only where the eval says you need it. | Lessons 3 and 4 |
| 5 | A developer reaches Claude over a REST API, usually through an SDK. | Choose between synchronous, streaming, async/await, or batch based on whether a user is waiting and whether the workload is real-time or bulk offline. | Lesson 5 |
What comes next
Module 2 puts these foundations to work across prompting craft, tool schemas, streaming, context engineering, and agent construction.
