ChatGPT Go vs ChatGPT Plus
Go is a chat plan. If you are here to code, the honest answer is that the Codex agent starts at Plus.
Updated August 28, 2026 · Independent comparison — ChatGPT Go, ChatGPT Plus are separate products.
ChatGPT Go
OpenAI's $8 chat tier
ChatGPT Go is OpenAI's $8/month tier, and it is a chat plan rather than a coding-agent plan. It runs GPT-5.6 Luna for everyday and Think use, with unlimited everyday text chats subject to abuse guardrails, but GPT-5.6 Sol is not included and the full Codex agent, Deep Research, Sora and Agent Mode all require Plus or above. There is a Codex Mobile preview on some surfaces. There is no annual option, no usage-credit overage and no API key.
ChatGPT Plus
OpenAI's $20 seat, Codex included
ChatGPT Plus is OpenAI's $20/month seat and the entry point for real Codex work — web, CLI, IDE and iOS — plus GPT-5.6 Sol, Terra and Luna. Its limit structure moved twice this year: OpenAI removed the 5-hour window on 2026-07-12 during a Sol traffic spike, then restored it for Plus on 2026-08-25, so Plus is once again capped on a 5-hour window stacked on a weekly one. Past either window you wait, or buy extra Codex credits on the token-based rate card. There is no annual billing.
Bottom line
ChatGPT Go at $8/month is a chat tier, not a coding-agent tier. It runs GPT-5.6 Luna with unlimited everyday text chat subject to abuse guardrails, and there is a Codex Mobile preview on some surfaces — but the full Codex agent across web, CLI and IDE, plus GPT-5.6 Sol, Deep Research, Sora and Agent Mode, all require ChatGPT Plus at $20/month. Plus is also where the usage structure gets real: a 5-hour window, restored on 2026-08-25, stacked on a weekly cap, with extra Codex credits available on OpenAI's token rate card when you run out. Go has no overage path at all — you wait. If you write code, the $12 difference is not optional.

1DevToolOne window, every agent you're paying for
Whichever seat wins here, you end up locked to one vendor's harness — and most of these subscriptions are contractually barred from driving anything else. 1DevTool runs Claude Code, Codex CLI, Cline, OpenCode and Gemini CLI side by side in persistent terminals, so you can put each subscription behind the agent it's actually licensed for and switch between them without switching windows. It adds an HTTP client, a 13-engine database client and an embedded browser too. One-time $29, no subscription.
