OpenAI Codex is the coding agent that runs across ChatGPT, an IDE extension, the CLI and cloud environments on a single ChatGPT account, with cloud worktrees, scheduled background tasks, Skills and code review. The Codex pricing documentation lists Free at $0/month for "quick coding tasks", Go at $8/month, Plus at $20/month, Pro from $100/month, Business at $20/user/month billed annually ($25 monthly, minimum 2 users) and Enterprise/Edu by contact, plus an API-key route billed at API rates. Usage is measured as messages per five-hour period that vary by model: on Plus, the documented ranges run from 250-2,000 messages for GPT-5.6 Luna down to 5-45 for GPT-6 Astra, and OpenAI states these are estimates rather than fixed limits.

Codex Free is $0/month, described as "Explore Codex capabilities on quick coding tasks"; no fixed free message count is published (Codex pricing docs, checked 2026-09-16).

Open-source local AI router (npm package '9router', MIT license, Next.js, by decolua). Connects CLI coding tools (Claude Code, Codex, Cursor, Gemini CLI, Cline, OpenCode, Antigravity, Copilot and any OpenAI/Claude-compatible client) to 40+ AI providers and 100+ models through a local OpenAI/Claude-compatible endpoint. Features: RTK token compression (20-40% savings on tool results), auto-fallback (subscription -> cheap -> free), multi-account round-robin, web dashboard. Self-hosted; users bring their own upstream accounts/keys. Implementation inspired by CLIProxyAPI.

Software is free (MIT); it routes through user-provided upstream accounts, no credits or prices from the router itself.
