A free tier is a marketing budget
Providers open free access to win developers and close it when demand outgrows the budget. In 2026 GitHub retired GitHub Models entirely, Cerebras’ documentation describes a 30-day trial with a payment method, and Google’s rate-limits page gives no free-tier figure per model. A tutorial written a few months earlier still tells you otherwise.
What the log records
An entry is created when a re-read of an official page differs from what this site had recorded, and when a model enters or leaves the OpenRouter zero-price list between two daily collections. Every entry links to its source. Rumours and third-party posts are not entries.
Design for the day it ends
Keep the base URL, the model id and the key in configuration; keep a second provider tested; handle the rate-limit error instead of crashing. The OpenAI-compatible page lists providers that take the same code.
