Claude vs ChatGPT comes down to one question: do you mostly work through long documents, or do you want one app that also makes images, talks back and runs tasks on a schedule? Claude is Anthropic's assistant, and its plans list a much larger context window. ChatGPT is OpenAI's assistant, and its plans pack more tools and more price points. Both cost $20 a month at the standard paid tier, so price won't decide this for you. Below: plans, limits and features side by side, checked on each company's own pages, plus a verdict for each tool.
Last verified: October 8, 2026. We read Anthropic's Claude pricing page and model docs, plus OpenAI's ChatGPT pricing page and ChatGPT and Codex pricing docs, on that date. This comparison is built from those documents, not from our own hands on tests, so it tells you what each plan includes, not which tool writes the better email. Both companies change plans often: OpenAI's docs already list GPT-5.5 for retirement on October 14, 2026. If you're reading this more than two months after the date above, recheck the prices before you pay.
What kind of tools are Claude and ChatGPT?
Both are general AI assistants with a chat app on web, desktop and mobile. Both also bundle a coding agent and some kind of task automation into their plans. They don't sit in different categories. They sit in the same category with different priorities, and the plan pages show it.
| Category | What it means here | Claude | ChatGPT |
|---|---|---|---|
| Chat assistant | Ask, write, summarize, analyze files | Claude app, Free and up | ChatGPT app, Free and up |
| Long document work | How much text it keeps in view at once | Up to 1M tokens, varies by model | 27K to 400K tokens, depends on plan and model |
| Visual output | Images, designs, decks | Claude Design, Slides and Docs on every plan | Image generation, limited on Free |
| Task automation | Work that runs without you typing | Hand off and schedule tasks, Pro and up | Scheduled tasks, Go and up |
| Coding agent | Reads a project, edits files, runs commands | Claude Code, Pro and up | Codex, limited on Free and Go |
The row people get wrong is visual output. Claude's plan page doesn't list an image generator. What it lists is Claude Design, Slides and Docs, which Anthropic says build designs, one pagers and decks you can export to PowerPoint or PDF. ChatGPT is the one that lists image generation as a plan feature.
Claude vs ChatGPT plans and prices (checked October 8, 2026)
| Plan level | Claude | ChatGPT |
|---|---|---|
| Free | $0: Sonnet and Haiku models, web search, file creation, code execution, memory, up to 5 projects | $0: unlimited text chats with GPT-6 (subject to abuse guardrails), limited uploads, images, deep research and Codex |
| Budget tier | No equivalent | Go, $8/month: more messages, uploads and images; the plan "may include ads" |
| Standard | Pro, $20/month, or $17/month billed annually ($200 up front): Claude Code, Opus models, Research | Plus, $20/month: advanced reasoning models with GPT-6, scheduled tasks, custom GPTs, expanded Codex |
| Heavy use | Max, from $100/month: 5x or 20x Pro's usage | Pro, from $100/month: three usage tiers, Dot agent, unlimited image creation |
| Teams | Team, for teams of 2 to 150 | Business, available from 2 users |
We left team prices out on purpose. Neither pricing page showed a Team or Business price on the day we checked, so check them with each company directly.
Two things that table doesn't say out loud. First, Claude's annual Pro plan saves real money: $200 a year instead of $240. ChatGPT sells Plus monthly only; its billing FAQ says annual plans are for Business and Enterprise. Second, ChatGPT's ladder has more rungs. If $20 feels like too much, Go at $8 exists. Claude has nothing between Free and Pro.
Context window: the difference you'll actually feel
The context window is how much text the model keeps in view at once: your document, the chat so far and its own reasoning. It decides whether you can paste a whole contract, a quarter of meeting notes or a long report, or whether you have to chop it into pieces.
| Plan level | Claude | ChatGPT, Instant model | ChatGPT, reasoning model |
|---|---|---|---|
| Free | Up to 1M tokens, varies by model | 27K tokens total (about 12 pages of input) | Varies |
| $20 tier | Up to 1M tokens, varies by model | 54K tokens total (about 40 pages of input) | 256K tokens total (about 320 pages of input) |
| Top tier | Up to 1M tokens, varies by model | 128K tokens total (about 250 pages of input) | 400K tokens total (about 680 pages of input) |
Read the Claude column with care. The plan page says "up to 1M, varies by model," so don't assume every chat gets the full million. Anthropic's model docs list a 1M token window for each current model: Fable 5.1, Opus 5.5, Sonnet 5.5 and Haiku 5.5. On ChatGPT's side, the page counts are OpenAI's own estimates of how much input fits.
The gap is still wide. On the $20 tier, ChatGPT's Instant model holds about 40 pages of your input. If your job runs on long PDFs, transcripts or spreadsheets, this is the axis that settles it.
Claude: what you get and what doesn't get said
Claude's lineup has four model families: Fable, Opus, Sonnet and Haiku. The newest versions are Fable 5.1, Opus 5.5, Sonnet 5.5 and Haiku 5.5, and Anthropic's docs suggest starting with Opus 5.5 for most workloads. Free gets Sonnet and Haiku. Pro adds Opus, Claude Code, Research, and Claude in Chrome and Microsoft 365.
The free plan is generous on tools. It includes web search, file creation, code execution, memory, connectors, Artifacts, voice mode, and Claude Design, Slides and Docs.
What doesn't get said. Claude doesn't publish message counts. Usage runs on a rolling five hour session, and paid plans add weekly limits on top. Anthropic only commits to ratios: Pro gives at least 5x Free's usage per session, and Max gives 5x or 20x Pro's. Your chats and your Claude Code sessions draw from the same pool, so a long coding afternoon eats into your writing budget. Fable isn't really included on Pro either: it runs on usage credits there. Designs and decks also count toward your limit, and Anthropic says a full deck uses more than a typical message.
Verdict: best if your work lives in long documents and you want the biggest context window at $20. Avoid it if you need a plan under $20, or if limits without a fixed number make budgeting stressful.
ChatGPT: what you get and what doesn't get said
ChatGPT's Free plan offers unlimited text chats with GPT-6, subject to abuse guardrails. Plus adds advanced reasoning with the GPT-6 models, along with scheduled tasks, custom GPTs and expanded Codex. Pro adds pro reasoning powered by GPT-6 Astra and Dot, an agent OpenAI describes as always on. Projects are on every plan, Free included.
What doesn't get said. The model names change under you. OpenAI's docs say GPT-5.5 retires from ChatGPT, ChatGPT Work and Codex on all plans on October 14, 2026. If a tutorial tells you to pick GPT-5.5, it's already out of date. GPT-6.1 Sol, which the pricing page lists for Plus, lives in Work and Codex, not in regular chat, per OpenAI's docs.
The $8 Go plan "may include ads," per OpenAI's own pricing page. And Codex usage on Plus is shown as ranges, not promises: OpenAI estimates 15 to 160 local messages per five hours with GPT-6.1 Sol and calls those "not fixed message limits."
Verdict: best if you want one app for writing, images, voice and scheduled tasks, or you need a paid plan under $20. Avoid it if your work depends on pasting very long documents into the Instant model.
Claude vs ChatGPT for coding, in one paragraph
Both bundle a coding agent. Claude Code comes with every paid Claude plan and shares your chat usage. Codex comes in limited form on ChatGPT Free and Go, and with expanded usage on Plus. So you can try Codex without paying, and you can't try Claude Code without paying. If code is your main use, our comparison of AI coding agents goes much deeper.
How to run your own 10 task test
Plan pages tell you what you're allowed to do. They don't tell you which answer you'll like better. That part only you can test, on your own work. Here's a method you can run in an afternoon. Tasks 1 to 9 work on both free plans; task 10 needs ChatGPT Go or Claude Pro. We haven't published results for it; it's a checklist for you to run.
- Summarize a long document you know well. Use a real report or contract. Check what each tool left out.
- Draft a hard email. Give the same context to both, then count how many edits you'd make before sending.
- Clean up messy meeting notes. Ask for decisions, owners and dates.
- Analyze a spreadsheet. Upload the same file and ask the same three questions.
- Rewrite for a different audience. Turn a technical paragraph into one for your manager.
- Plan a project. Ask for a two week plan with risks, then push back once.
- Research a question with sources. Check whether every source actually says what the tool claims.
- Build a reusable prompt. Save it in a project and run it three times on different inputs.
- Make something visual. A one pager, a slide or an image, whichever your job needs.
- Set up something that runs without you. A scheduled task on ChatGPT Go or Plus, or a scheduled task on Claude Pro.
Use identical prompts, judge each output before you look at the other, and write down the edits you'd make. The tool that needs fewer edits on the tasks you do most is your answer.
Which one should I pick?
| Your situation | Pick | Why |
|---|---|---|
| You work through long documents | Claude Pro | Up to 1M tokens of context vs 54K on ChatGPT Plus's Instant model |
| You want images and voice in one app | ChatGPT Plus | Image generation is a listed plan feature; Claude lists design tools instead |
| Your budget is under $20 | ChatGPT Go | $8/month; Claude has no tier between Free and Pro |
| You want to try a coding agent for free | ChatGPT Free | Codex is included in limited form; Claude Code starts at Pro |
| You pay yearly to save | Claude Pro annual | $200/year; ChatGPT Plus is sold monthly |
| You're buying for a team | Ask both for a quote | Neither pricing page showed a team price on October 8, 2026 |
| You use AI all day and hit limits | Claude Max or ChatGPT Pro | Both start at $100/month; pick the one whose $20 plan you outgrew |
What if you're learning to use AI for work?
This is the case where the choice matters least and the habit matters most. Plenty of people use ChatGPT or Claude a few times a week, get a decent answer, and never build a system around it. Switching tools won't fix that.
Three rules work with either tool:
- Start from your real tasks, not from the tool. List the five things you repeat every week, then test both assistants on those.
- Save what works. A prompt that gets a good result once belongs in a project or a prompt library, not in your chat history.
- Stay on the free plan until a limit blocks you. Upgrade when a real cap gets in your way, not because a comparison told you to.
Knowing which assistant to open is the easy part. The harder part is turning it into a workflow that saves you time every week. That's what the AI Fluency program works on: four weeks, no coding required, one live class per week and a 1:1 mentorship session. Week one covers how AI models work and why model choice matters for cost and quality, which is this whole article in practice. You finish with a prompt library and a working automation built around your own job.
