ChatGPT vs. Claude: Which AI Should You Use?
ChatGPT is the better pick for most people: it does the most things well, from images and voice to deep research, and its free tier is the most generous. Claude is the one to choose if your work is mostly writing or code.
ChatGPT packs image creation, voice, deep research and the Codex coding agent into one app, with the most generous free tier and the widest ladder of plans.
Claude Opus 5.5 leads LMArena’s creative-writing and web-development rankings, Claude Code comes with Pro, and every plan advertises a context window of up to 1 million tokens.
The Research Score rates each product on its own merits. Our picks also weigh price and who the product is for, so a pick can rank above a higher-scoring product. How we score
ChatGPT and Claude both cost $20 a month for their main paid plans at the time of research, both have a free tier, and both now come with a coding agent (Codex for ChatGPT, Claude Code for Claude). So the choice comes down to what you do most.
Our short answer: ChatGPT is the better all-rounder. It covers chat, image creation, voice, deep research and coding in one app, its free tier includes unlimited everyday text chats, and OpenAI’s image models top the public image leaderboard. Claude is the better pick if most of your work is writing, editing or code: Anthropic’s Claude Opus 5.5 ranked first on LMArena’s creative-writing and web-development leaderboards at the time of research, and every Claude plan advertises a context window of up to 1 million tokens.
Below we compare the two on writing, coding, research, images, voice, file limits, usage limits, price and privacy, based on OpenAI’s and Anthropic’s own pricing, help and privacy pages and on LMArena’s public rankings. We did not test either tool hands-on.

Why you should trust us
We compared ChatGPT and Claude using OpenAI’s and Anthropic’s own pricing pages, help centers and privacy documentation, all checked on October 27, 2026 (see Sources). For quality, we relied on LMArena, a public leaderboard built from millions of blind, head-to-head votes, rather than our own impressions. We scored both products with our published Research Score. We did not run hands-on tests for this comparison, and we don’t describe any personal experience with either tool. If you’re also weighing Google’s assistant, see our three-way ChatGPT vs. Claude vs. Gemini comparison.
The short answer
Choose ChatGPT if you want one assistant for a bit of everything: quick questions, drafts, images, voice conversations, deep research and occasional coding. It’s also the better free option.
Choose Claude if most of your AI use is long-form writing, editing, analyzing long documents, or building software, and you’re willing to pay $20 a month (or $17 billed annually) for the Opus model and Claude Code.
Use both free tiers if you’re unsure. They’re different enough that many people keep one for writing and one for everything else.
How they compare, task by task
Writing. Claude has the edge on independent rankings: Claude Opus 5.5 ranked first in LMArena’s creative-writing category at the time of research. Its large context window also helps with editing long manuscripts or reports in one go. ChatGPT is a capable writer too, and its add-ins for Word, Excel, PowerPoint and Google Sheets bring it into the documents you already use.
Coding (Codex vs. Claude Code). Both companies now bundle an agentic coding tool with the $20 plan. OpenAI says Codex on Plus runs on the web, in the CLI, in IDE extensions and on iOS, with automatic code review and a Slack integration; OpenAI estimates 15 to 160 local messages per five hours with GPT-6.1 Sol on Plus, depending on the task. Anthropic says Claude Code runs in the terminal, IDEs (VS Code and JetBrains), a desktop app, the web, Slack and GitHub, and needs Pro or Max. On LMArena’s WebDev leaderboard, Claude Opus 5.5 was first and GPT-6 Astra second. Codex has a limited free option; Claude Code doesn’t. Our best AI coding assistant guide covers more options.
Research. ChatGPT includes deep research on every plan (limited on Free, expanded on Plus, maximum on Pro). Claude’s Research feature needs Pro or Max.
Image generation. Only ChatGPT. Claude’s pricing page doesn’t list it, and OpenAI’s image models led LMArena’s text-to-image ranking. See our best AI image generator guide.
Voice. Both have it on every plan. OpenAI lists voice as limited on Free and expanded on Plus, with voice and video chats on Plus. Claude lists voice mode on Free, Pro and Max.
Files and context. Claude advertises up to 1 million tokens on all plans and accepts up to 20 files per chat at up to 500 MB each. ChatGPT’s Instant model has 54,000 tokens on Plus (256,000 for reasoning models); documents can be up to 512 MB, and OpenAI allows up to 80 uploads every three hours, but only three a day on Free.
Usage limits. ChatGPT Free offers unlimited everyday text chats, with separate caps on tools. Claude uses a five-hour session limit plus a weekly limit on paid plans, with no fixed message count.

ChatGPT
8.2/10
ChatGPT packs image creation, voice, deep research and the Codex coding agent into one app, with the most generous free tier and the widest ladder of plans.
ChatGPT wins the all-rounder slot because it does the most things in one place. OpenAI’s pricing page lists web search, file and image uploads, image creation, voice chats, a limited amount of deep research and limited Codex access even on the Free plan, and OpenAI’s help center says Free users get unlimited everyday text chats, subject to abuse safeguards. Uploads, image generation, voice and data analysis have their own, separate limits.
Plus ($20 a month, billed monthly) adds advanced reasoning models, more complex and precise image creation, expanded deep research, projects and scheduled tasks, voice and video chats, and expanded Codex use, according to OpenAI. There’s also a cheaper Go plan, which OpenAI’s Codex pricing page lists at $8 a month, with more messages, uploads, images and voice than Free; OpenAI says Go may show ads. Heavy users can step up to Pro at $100, $200 or $500 a month.
Image generation is ChatGPT’s clearest advantage over Claude. Claude’s pricing page doesn’t list image generation at all, while OpenAI’s image models held the top three places on LMArena’s text-to-image leaderboard at the time of research (the top two marked as preliminary). Rankings measure the underlying models rather than the ChatGPT app, but they’re a useful independent signal.
Flaws but not dealbreakers
ChatGPT’s standard context window is small by comparison. OpenAI’s plan comparison lists 27,000 tokens (about 12 pages of input) for the Instant model on Free and 54,000 tokens (about 40 pages) on Go and Plus; the reasoning models get 256,000 tokens on Plus and 400,000 on Pro. Claude advertises up to 1 million tokens on every plan.
Privacy defaults also need attention. OpenAI says “Improve the model for everyone” is on by default for personal Free, Plus and Pro accounts, so your chats and Codex tasks can be used for training until you switch it off. And on LMArena’s overall text leaderboard, OpenAI’s highest-ranked model placed 21st at the time of research, well behind Claude Opus 5.5 in second.
Who it’s for
People who want one AI for many jobs: everyday questions, drafting, images, voice conversations, research and some coding.
Who should skip it
Most of your work is long-form writing or code, or you want a very large context window without paying for a Pro plan.

Claude
7.5/10
Claude Opus 5.5 leads LMArena’s creative-writing and web-development rankings, Claude Code comes with Pro, and every plan advertises a context window of up to 1 million tokens.
If your main use is writing, editing or coding, Claude is the one to pay for. On LMArena, where people vote blind on which of two anonymous answers is better, Anthropic’s Claude Opus 5.5 ranked first in the creative-writing category and first on the WebDev leaderboard at the time of research, ahead of OpenAI’s GPT-6 Astra in second. On the overall text leaderboard it placed second, behind Google’s Gemini 4 Argon.
You have to pay to get that model. According to Claude’s pricing page, the Free plan includes the Sonnet and Haiku models, memory, connectors, voice mode, and file creation with code execution, but not Opus, Research, Claude Code or Claude in Chrome. Pro costs $20 a month, or $17 a month if you pay $200 up front for a year, and adds Opus, Research, Claude Code, Claude in Chrome, and Claude for Microsoft 365 and Outlook. Max starts at $100 a month for five or 20 times Pro’s usage.
Claude’s other big advantage is room to work. Its pricing page lists a context window of “up to 1M” tokens on every plan, depending on the model, and Anthropic’s help center says you can attach up to 20 files per chat, at up to 500 MB each, with PDFs of up to 1,000 pages.
Flaws but not dealbreakers
Claude doesn’t list image generation on its pricing page, so if you want an assistant that makes pictures, ChatGPT is the better fit. It can create and edit files such as documents and spreadsheets with code execution, but not images.
Usage is also less predictable. Anthropic says Pro limits reset every five hours, that there’s a separate weekly limit across all models, and that the number of messages varies with message length, file size, conversation length and the model you use. The pricing page promises at least five times Free’s usage per session on Pro, but no fixed message count.
Who it’s for
Writers, editors, analysts and developers who work with long documents or codebases and want the model public rankings rate highest for that.
Who should skip it
You want image generation, or you'll stay on the free tier, which doesn't include Opus, Research or Claude Code.
Pros
Claude Opus 5.5 ranked first on LMArena for creative writing and web development
Context window of up to 1M tokens on all plans, depending on the model

Price compared
All prices at the time of research:

Power users

Max: from $100/month (5x or 20x Pro usage)
The headline price is a tie at $20 a month. Claude is cheaper if you pay annually ($17 a month), and ChatGPT is cheaper if you only need a step up from Free, thanks to Go. OpenAI says its Pro plans are billed monthly only, and Pro 500 is the only tier with the faster Ultrafast mode. If you’d buy one of these mainly for coding, note that OpenAI says Codex and ChatGPT Work share the same usage allowance, and that Plus users who hit their limit can buy credits instead of upgrading.
Privacy compared
Both companies can use your consumer chats to improve their models, and both let you limit that:
ChatGPT: OpenAI says data sharing is on by default for personal Free, Plus and Pro accounts. Turn off “Improve the model for everyone” under Settings > Data controls; the setting also covers Codex tasks. Temporary chats aren’t used for training but may be kept for up to 30 days for safety. If you rate a response with a thumbs up or down, OpenAI says the whole conversation may be used for training even after you opt out. Ads, where they appear on Free and Go, don’t share your conversations with advertisers, according to OpenAI.
Claude: Claude’s pricing page lists model training as “opt-out” on Free, Pro and Max. Anthropic says incognito chats are never used for training, even with Model Improvement on. If you allow model improvement, it may keep new chats and coding sessions in de-identified form for up to five years; deleted conversations leave its back-end storage within 30 days.
On both services, business plans (ChatGPT Business and Enterprise, Claude Team and Enterprise) are handled differently; OpenAI says it doesn’t train on business workspace content by default. If privacy matters to you, check the training setting in whichever app you choose, and use temporary or incognito chats for anything sensitive.
The bottom line
For most people, ChatGPT is the better choice: it does more things, its free tier is the most generous, it’s the only one of the two that makes images, and Go offers a cheap step up. Choose Claude if your work is writing or code. Its top model leads public rankings for both, it gives you up to 1 million tokens of context on every plan, and Claude Code is included with Pro.
Still undecided? Try both free tiers on the same real task, such as a document you need to edit or a bug you need to fix, and keep the one you reach for. For more context, see whether ChatGPT Plus or Claude Pro is worth it, or our guide to the best AI chatbot.
