Question

A technical lead is migrating their agent from a 200K token context model (Claude Sonnet 4.5) to a 1M token context model (Claude Sonnet 4.6). They expect to handle longer documents. What other consideration should they account for with the larger context?

Accepted Answer

A. The 1M context model has the same pricing per token, so costs only increase proportionally to usage

Answer

B. Prompt caching minimum thresholds differ between models — Sonnet 4.5 has 1024 token minimum while Sonnet 4.6 has 2048 token minimum, affecting caching strategy

Answer

C. The architecture doesn't need any changes — just update the model parameter

Answer

D. The response quality is identical regardless of context length
