ChatGPT Pricing & Plans Explained: Free vs Go vs Plus vs Pro (2026)

TL;DR. ChatGPT has a free plan (GPT-5.5 in standard chat, GPT-5.6 Terra in Codex/Work), a budget Go plan ($8/month with the same model split and roomier limits), a Plus plan ($20/month) that unlocks GPT-5.6 Sol in standard ChatGPT and Sol/Terra/Luna in Codex and Work, and a Pro plan with a usage toggle: $100/month for 5× Plus usage or $200/month for 20×, plus the Pro model level. Business ($20–25/seat) and Enterprise (custom) cover organizations.

OpenAI's pricing ladder got longer in 2026 — there are now six rungs, and the plan cards don't make it obvious which GPT model you're actually getting on each. Here's the plain-English version, checked against the live pricing page and model picker in July 2026.

The plans, top to bottom

Free — $0. Use ChatGPT at chatgpt.com with no payment. Standard chat runs GPT-5.5 with a limited allowance, while Codex and ChatGPT Work can use GPT-5.6 Terra. Good for trying things out and casual questions.

Go — $8/month. The budget tier: more messages and uploads, more image creation, longer memory, and expanded voice mode compared to Free. Standard chat stays on GPT-5.5 rather than Sol, but Codex and ChatGPT Work can use GPT-5.6 Terra. OpenAI also notes that Go may include ads.

Plus — $20/month. The plan most working professionals want. Plus unlocks the GPT-5.6 flagship, Sol, in regular ChatGPT and the full Sol / Terra / Luna family in Codex, along with advanced image creation, expanded memory across chats, the Codex coding agent, the Work agent for multi-step tasks, expanded deep research, and Projects and custom GPTs. If ChatGPT is part of your workday, this is the default choice.

Pro — $100 or $200/month. One plan, two usage levels: a toggle on the pricing page picks 5× Plus usage for $100 or 20× for $200. Both add the Frontier Pro model (the Pro intelligence level — you'll see it called Sol Pro), maximum access to the Codex and Work agents, unlimited core chat and faster image creation ("unlimited subject to abuse guardrails," per OpenAI), maximum memory and context, and early access to experimental features. Pro is for people running agents hard all day — if you're not hitting Plus limits, you don't need it.

Business — about $20–25 per seat/month. Roughly $20/seat on annual billing ($25 monthly), with admin controls, SSO, and workspace management. The "ChatGPT for the whole office" option.

Enterprise — custom pricing. SCIM provisioning, data residency, compliance controls, and volume terms. Priced by sales, not self-serve.

Which model you actually get

This is the part the plan cards bury. As of July 2026, the current family is GPT-5.6, released July 9: Sol (flagship), Terra (balanced intelligence and cost), and Luna (high-volume and low-cost). Codex lets eligible subscribers select those models directly. Regular ChatGPT may present the family through product-level model or intelligence controls rather than exposing the raw API IDs; the July plan snapshot shows Instant (5.5) for quick answers and Sol-based higher-intelligence levels, with the Pro level reserved for Pro plans.

Standard Free and Go chat stayed on GPT-5.5 when GPT-5.6 shipped. Their exception is agentic work: Codex and ChatGPT Work provide Terra access. Sol in standard ChatGPT begins on eligible paid plans.

"Wait, is this the API or the subscription?"

Same trap as every AI product: there are two completely separate ways to pay OpenAI.

• The subscription (Free / Go / Plus / Pro / Business / Enterprise) — a flat monthly fee for using ChatGPT, the apps, and the bundled agents. This is what almost every professional wants.
• The API — pay-per-use pricing in tokens, for developers building GPT into their own software. Current standard rates for requests with up to 272K input tokens are Sol $5/$30, Terra $2/$12, Luna $0.20/$1.20 per million input/output tokens. Cached input is $0.50, $0.20, and $0.02 respectively; longer-context requests cost more.

If you just want to use ChatGPT for work, the per-token numbers have nothing to do with your bill.

Where Codex and ChatGPT Work fit

Codex and ChatGPT Work are plan features rather than separate subscriptions. Free and Go can use GPT-5.6 Terra in both surfaces. Plus, Pro, Business, and Enterprise can choose Sol, Terra, or Luna, with the higher plans providing more usage. Work completes multi-step tasks across connected apps; Codex focuses on software work. Consumption still depends on model, context, reasoning, tools, and task complexity.

Custom GPTs don't cost extra either — building and using them is included from Plus up.

How many images can you generate on each plan?

A question we get a lot — and one OpenAI doesn't answer with fixed numbers. As of July 2026 the practical picture: Free gets roughly 2–3 image generations per day. Go is marketed as about 10× Free's image creation — call it a couple dozen a day, flexing with demand. Plus users commonly report around 40–50 images per rolling 3-hour window. Pro includes "unlimited and faster image creation" subject to abuse guardrails — the only tier where you effectively stop counting. These are observed numbers, not published caps: OpenAI adjusts them with demand, so the banner inside ChatGPT is the source of truth for your account. For the full cross-vendor picture — including message caps and how Gemini's published image limits compare — see AI usage limits compared.

Which plan should you actually pick?

• Just exploring? Start on Free.
• Heavy casual use, budget matters? Go ($8/mo) — knowing you're not on the flagship model.
• Using ChatGPT for real work most days? Plus ($20/mo) — flagship model, Codex, Work agent, custom GPTs.
• Running agents constantly, hitting limits? Pro — start at the $100/5× level; jump to $200/20× only if you actually hit the ceiling.
• Rolling it out to a team? Business, or Enterprise for compliance controls.

Start at Plus. Move up when you feel a limit, not before.

How this compares to Claude

The ladders mirror each other almost rung for rung: both anchor at $20/month for the individual plan (ChatGPT Plus vs Claude Pro) and both sell $100/$200 power tiers (ChatGPT Pro vs Claude Max). ChatGPT's real pricing edge is the $8 Go tier Claude doesn't match; Claude's is that its desktop agent (Claude Cowork) is included on every plan, even Free. If you're choosing between the two $20 plans, price won't decide it — see the full Claude vs ChatGPT comparison for where each genuinely wins, and what shipped in GPT-5.6 for the latest on OpenAI's side.
