Four kinds of posts live here: setup guides (pointing Claude Code, Codex, Cursor and Cline at a new base URL), pricing and cost accounting (what you actually pay per million tokens), comparisons (how aggregators differ), and stability and trust (how to verify a platform yourself). Occasionally there is one about access and payment — what to do when the sign-up flow itself is the blocker.
Looking for current prices? The model plaza publishes per-model rates and group multipliers, and the status page shows how each group is running right now.
