GPT-5.5 Instant

The default fast model in ChatGPT subscriptions—for everyday writing, Q&A, light code, and multimodal chat. Free has limited access; Go raises quotas; Plus and above reach expanded or unlimited levels per the pricing comparison table.

GPT-5.5 Thinking

GPT-5.5 with extended thinking, available from Plus onward—for complex reasoning, multi-step analysis, and higher-accuracy tasks; typically consumes more message/thinking quota than Instant.

GPT-5.5 Pro

The top reasoning model for Pro subscriptions—sustained heavy coding, Deep Research, and long-context work. Plus does not include full Pro-level access; requires Pro 5x or Pro 20x.

GPT-5.3 Instant

Pro card lists unlimited GPT-5.3 and file uploads; after GPT-5.5 Instant became default, Plus/Pro paid users can still select GPT-5.3 Instant in settings/model picker (OpenAI announced ~3-month transitional availability—check latest notice).

Codex

Built-in AI coding agent on ChatGPT web (pricing Features: Codex)—Free has limited access, Plus expanded usage, Pro maximum tasks; run coding tasks inside chatgpt.com, separate from platform.openai.com API pay-as-you-go billing.

Plan details

Go

Starter
Price
$8/mo
$8 monthly · US list price · may include ads
Official
Usage
Go expands on Free with more GPT-5.5 Instant messages, uploads, image creation, and longer memory—suited for daily writing, Q&A, and light assistant use rather than occasional trial access.
Models
Unlike Plus, Go does not include GPT-5.5 Thinking advanced reasoning, expanded Deep Research, Projects, custom GPTs, and similar advanced features—choose Plus for complex tasks and heavier Codex use.
Highlights
Official US pricing is $8/month; some regions show localized prices. This tier may include ads, while Plus and above remain ad-free.
If you do not yet need agent mode, Deep Research, or heavy Codex quotas, Go is usually a more economical paid entry tier than jumping straight to Plus.
Best for
Individual users from occasional to moderate use, light writing/Q&A, and developers not yet needing Plus reasoning or Codex capacity

Plus

Most popularRecommended
Price
$20/mo
$20 monthly · US list price · ad-free
Official
Usage
Plus adds GPT-5.5 Thinking advanced reasoning on top of Go, with significantly expanded messages, uploads, voice, image creation, memory, and context—enough for most frequent personal use.
Models
Includes expanded Deep Research and agent mode, Projects/Tasks/custom GPTs, Canvas, and higher Codex quotas; models include GPT-5.5 Instant/Thinking, GPT-5.3 Instant (selectable in settings), GPT-5 Thinking Mini, legacy models, plus built-in Codex on the web.
Highlights
Official US pricing is $20/month, ad-free—best for using ChatGPT as a primary personal workspace without needing Pro’s GPT-5.5 Pro access or 5x/20x usage ceilings.
The main gaps vs Pro are top model access (GPT-5.5 Pro), Codex task ceilings, Deep Research/agent quotas, and whether uploads and image creation approach near-unlimited levels.
Best for
Frequent individual users, indie developers, and knowledge workers needing reasoning and Codex

Pro 5x

Pro 5x
Price
$100/mo
$100 monthly · ~5x Plus usage
Official
Usage
Pro 5x offers roughly 5x Plus limits on messages, tools, and advanced model usage—suited for individuals doing daily coding, Deep Research, and parallel projects.
Models
Unlocks GPT-5.5 Pro reasoning, maximum Codex tasks, and stronger Deep Research/agent quotas; Pro also includes unlimited GPT-5.3 and file uploads subject to abuse guardrails.
Highlights
Official US pricing is $100/month, ad-free; image creation is faster and near-unlimited, with higher Projects/Tasks/custom GPT quotas than Plus.
If you frequently hit Plus limits and need sustained GPT-5.5 Pro access but not Pro 20x’s 20x allowance, the 5x tier is usually the better-value Pro entry.
Best for
Heavy individual developers and researchers needing sustained Pro capacity without the 20x tier

Pro 20x

Pro 20x
Price
$200/mo
$200 monthly · ~20x Plus usage
Official
Usage
Pro 20x offers roughly 20x Plus usage for extreme individual users running parallel projects, all-day Codex, and Deep Research with fewer limit interruptions.
Models
Includes everything in Pro 5x plus emphasis on unlimited GPT-5.3 (including the GPT-5.3 Instant line), file uploads, faster near-unlimited image creation, and the highest Pro message/memory/Deep Research quotas.
Highlights
Official US pricing is $200/month, ad-free—meant for using ChatGPT as a primary production environment, not as a substitute for normal Business team seats.
Gets research previews of new features ahead of Plus; “unlimited” claims remain subject to abuse guardrails—extreme automated batch use may still hit throttling.
Best for
Extreme individual users, multi-project operators, and people using ChatGPT as an all-day production workspace
