Codex is bundled into ChatGPT plans, with Pro now at three price points.

Codex (CLI, IDE, cloud, desktop) is included in ChatGPT Free through Enterprise and shares usage with ChatGPT Work. Plus has published local-message ranges per 5 hours; Pro comes at $100, $200 and $500 with no 5-hour limit.

GPT-6 Luna at Standard speed in the desktop app (subject to rollout).

Lightweight coding tier. Cheap model, so dollars stretch far in tokens but not in intelligence.

Local messages per 5h: Astra 5-45, GPT-6.1 Sol 15-160, Luna 350-3,000. Weekly limits may apply. Buy credits to extend.

OpenAI states message ranges, not dollars. Estimate assumes mostly GPT-6.1 Sol usage at typical agentic task sizes (2-15 credits per task).

Adds Ultrafast mode (burns included usage at 8x Standard for Astra / Sol).

Ultrafast consumes allowance faster, so tokens per dollar at Ultrafast are lower than the headline.

Strengths

  • GPT-6.1 Sol scores 52 on the AA index at a fraction of the per-task cost of Opus 5.5 ($0.72 vs $5.98)
  • Clear credit rate card makes overflow pricing transparent
  • Cheap Luna model stretches the allowance for lightweight tasks

Watch out for

  • Dollar value of included usage is not published for any tier; our values are estimates
  • Fast (2.5x) and Ultrafast (8x) modes burn the included allowance much faster
  • GPT-5.5 retires from ChatGPT and Codex on 2026-10-14
