  "account": "Free models have their limitations due to rate limits, causing a 429 response when real usage is required. This article proposes an alternative approach: constructing a lightweight proxy that distributes workload across multiple free endpoints, such as MonkeyCode's free option. The article emphasizes that rate limits should be viewed as a scheduling challenge rather than a budget issue. The proxy pattern functions as a traffic controller, directing app requests to the appropriate upstream model based on factors like health, quota, latency, and failure modes. The core logic revolves around a straightforward loop: determine which upstreams are healthy and within quota, select one, call it, and return the result. In case of failure, mark the upstream as unhealthy and proceed with the next option. The Python code demonstrates a minimal implementation using httpx for asynchronous HTTP calls and an in-memory counter for quota tracking. The Upstream class manages a 60-second sliding window, with functions to check if an upstream can be used and reserve a quota. The route() function traverses the list of upstreams, skipping unhealthy or exhausted ones, and raises an error if all options are exhausted. The article concludes by discussing resilience enhancements, such as marking an unhealthy upstream as unavailable for a cooldown period upon exception and implementing a retry loop with a delay for bursts of requests. Deployment is straightforward, requiring only Python, httpx, and a free server like MonkeyCode's option for hosting.",
  "summary": "Free models are not useless; they are just rate-limited. The moment you try to run something real against them, you hit a wall: a 429 that arrives exactly when you need an answer. The standard advice is to pay your way out. This article takes the opposite path: build a small proxy that spreads your workload across several free endpoints, including the one from MonkeyCode, and treat rate limits as…",
