As advertised. Free + Go: UNLIMITED GPT-5.6 Luna text chats (now the default model, LIVE as of ~Aug 11-13 2026; removes the old ~10 msgs/5h cap) — still capped at ~2-3 image generations/24h, ~3 file uploads/day and limited voice. Plus + Pro: default is GPT-5.6 Sol with a thinking-effort slider; Luna is available there too but NOT unlimited — it keeps per-5h caps (Plus Luna 250-2,000/5h; Pro 5x 1,250-10,000; Pro 20x 5,000-40,000), as do Sol/Terra (Plus ~10-100 Sol / 25-200 Terra; Pro 5x ~50-500 / 125-1,000; Pro 20x ~200-2,000 / 500-4,000). Codex (the coding agent): Free/Go get a LIMITED Terra allowance for quick tasks — Luna in Codex needs Plus+. All of this is the ChatGPT app + Codex, NOT the API: to use any of these models in a third-party agent you pay the API per-token, no subscription unlocks API access.

What that actually means. Codex publishes per-model message ranges and a credits-per-1M-tokens table, but never how many credits a plan includes -- burn rate without a budget. Plain ChatGPT chat has no remaining-usage view at all.

Where to check what is left. chatgpt.com/codex/settings/usage and CLI /status

The only Western lab publishing concrete numbers — but as ~6x-wide RANGES, which is itself an admission limits are dynamic. Codex moved to token-aligned metering 2026-04-02. IMPORTANT: since 2026-06-24 Codex seats are no longer available to new ChatGPT Business plans (medium confidence — verify). NOT COMPATIBLE WITH THIRD-PARTY HARNESSES — a ChatGPT subscription (Free/Go/Plus/Pro) only drives OpenAI's own surfaces, the ChatGPT app and Codex. It does NOT work with opencode, Cursor, Hermes or any other third-party coding agent, which all need an OpenAI API key billed per token. A plan and an agent are separate purchases; no subscription tier unlocks API access.
