Free tokens are not free. They are a queue you join with your time, your retries, and your patience. Before you route any real workload through a free model endpoint, measure what the queue actually costs you.
The same mistake shows up in batch jobs all the time. Someone finds a free tier with a generous allowance, points their pipeline at it, and celebrates the zero on the invoice. Then the rate limiter answers the first burst with 429s, the client retries with exponential backoff, and the "free" job runs three times longer than the paid one would have. The invoice is still zero. The clock is not.
MonkeyCode is an open-source project that pairs free model access with a free server option — the kind of offer that looks unbeatable until you count the wall-clock. Disclosure: This article was prepared as part of MonkeyCode's product outreach. I am not here to sell you on it. I am here to give you a way to test whether its free capacity is actually cheap for your workload.
The claim, as of this writing, is simple: a free allowance of 10 million tokens, plus a server you do not pay for. Whether that is a good deal depends entirely on your traffic pattern. A free allowance is a budget, not a guarantee. You are sharing the endpoint with everyone else who found the same deal, and their bursts become your latency.
