Context Engineering: How to Manage Context for AI...

Claude's context window holds 200,000 tokens. Gemini's stretches to two million. But response quality starts degrading long before the window fills up. Window size doesn't solve the context problem — it masks it. Prompt engineering teaches you how to ask. Context engineering teaches you what to feed the model before asking. And the second one shapes the answer more than the first. Andrej Karpathy put it this way: "Context engineering — the delicate art and science of filling the context window w
