TL;DR I run a small de-shop. Every product I ship needs an LLM call somewhere - content generation, security analysis, classification, summaries. The economics only work if these calls average near-zero. The trick: never pay for what a free tier can do. Stack 5+ providers in a deterministic fallback chain so that when one rate-limits, account-bans, or hikes prices, the next one takes over within the same request - invisible to the user.
