"Should I use Claude or ChatGPT?" For most everyday tasks, either will do the job. The real differences show up in image generation, coding and long-document work, how the plans are packaged, and API pricing. This guide compares only what we could confirm in Anthropic's and OpenAI's official documentation on September 27, 2026, and it doesn't treat benchmark scores, which change constantly, as settled fact.
🟢 Model references match the current lineup · model notice · Fable subscription
Fable 5 and 5.1 subscription (updated September 7, 2026): Claude Fable 5.1, released September 1, 2026, is the current Fable model and Fable 5 is now legacy. Plan terms are the same for both — Max and Team Premium plans include Fable at up to 50% of the weekly usage limit; Pro and Team Standard use usage credits (
- Different makers — Claude is built by Anthropic, ChatGPT by OpenAI.
- The clearest feature gap is image generation — ChatGPT generates images; Claude makes diagrams, charts and SVG visuals instead of photos or illustrations.
- Both do voice and web search — Claude offers voice mode (beta) and web search on every plan, including Free.
- Both paid personal plans are $20/month — Claude Pro and ChatGPT Plus (US pricing).
- Top and mid-tier API prices now match — GPT-6 Astra and Fable 5.1 are $10/$50; GPT-6 Sol and Sonnet 5 are $2/$10 (per million input/output tokens).
The biggest difference: who makes them and what they focus on
The most basic difference is the company behind each one: Claude comes from Anthropic, ChatGPT from OpenAI. Both handle the core jobs well — writing, summarizing, translating, coding and answering questions — so the realistic question isn't which one is "better," but which fits the work you do.
The product lineups point in different directions. Claude leans toward a terminal coding agent (Claude Code) and document and deliverable work (Artifacts, Projects, Claude Design, Slides and Docs), and Anthropic publicly puts safety at the center of its research and products. ChatGPT leads with multimodal features, image generation included, and a broad set of third-party integrations.
Features side by side: images, voice and web search
| Feature | Claude | ChatGPT |
|---|---|---|
| Image generation | Doesn't generate photos or illustrations. Builds diagrams, charts and interactive visuals in HTML/SVG (beta on web and desktop) | Generates images (limited and slower on Free) |
| Voice chat | Voice mode (beta) on every plan, on mobile, desktop and web | Yes (limited on Free) |
| Web search | Yes, including the Free plan | Yes |
If you need to create pictures or photos, ChatGPT (or a dedicated image tool) is the one to use. For voice and up-to-date information, either works now. Older comparisons that sent you to ChatGPT for voice or live information are out of date: Claude now offers both voice mode and web search.
Strengths people mention most often
These are general impressions that come up repeatedly in comparisons and user reviews. They aren't official rankings and can shift with the task and the model version.
Claude
- Long documents and code — widely praised for large-context work and coding help.
- Claude Code — an agentic developer tool you run from the terminal, included with Pro and higher plans.
- Artifacts and Projects — outputs open in a side panel, and chats and files can be grouped into projects.
- Documents, slides and designs — the official pricing page lists Claude Design, Slides and Docs as Pro plan features.
- Safety-first direction — something Anthropic emphasizes publicly across its research and products.
ChatGPT
- Image generation — create images right inside the conversation.
- Broad ecosystem — a long-established user base and wide third-party integrations.
- More plan tiers — Free, Go, Plus and Pro give more price points to choose from.
How much it can take in at once (context window)
When you want to drop a whole long document or codebase into one conversation, the context window matters. According to Claude's help center, on paid plans Opus 5.5, Opus 5 and Sonnet 5 get 1 million tokens in chat, and other models default to 200K. On the API, Fable 5.1, Opus 5.5 and Sonnet 5 support 1M tokens and Haiku 4.5 supports 200K.
OpenAI's developer docs list a 1.05M-token API context window for GPT-6 Astra, Sol and Luna. Limits inside the ChatGPT app vary by plan; we couldn't confirm official figures, so we don't state them here.
Subscription plans
The standard paid personal plan costs $20 a month on both sides (US pricing).
| Tier | Claude | ChatGPT |
|---|---|---|
| Free | Free — Sonnet and Haiku models, web search, file creation, memory | Free — GPT-5.6 Luna, limited image generation and voice |
| Between Free and Plus | — | Go (see the official page for pricing) |
| Standard paid | Pro — $20/month ($17/month billed annually), includes Opus models and Claude Code | Plus — $20/month |
| Higher | Max — from $100/month | Pro (see the official page for pricing) |
Same headline price, different contents: Claude Pro includes Claude Code, while on ChatGPT the GPT-6 models and image-generation allowance you get depend on the plan. Plans change often, so check the Claude pricing page and ChatGPT pricing page before you subscribe.

API models and token prices (as of September 27, 2026)
If you call the models directly through the API, per-token prices decide the cost. OpenAI released GPT-6 Astra on September 3, 2026 and GPT-6 Sol and Luna on September 22; Anthropic launched Claude Opus 5.5 on September 22. Standard prices per million input/output tokens:
| Price band | OpenAI (GPT-6) | Anthropic Claude |
|---|---|---|
| Top | GPT-6 Astra — $10 / $50 | Fable 5.1 — $10 / $50 |
| Upper | — | Opus 5.5 — $4 / $20 |
| Mid | GPT-6 Sol — $2 / $10 | Sonnet 5 — $2 / $10 |
| Light | GPT-6 Luna — $0.10 / $0.50 | Haiku 4.5 — $1 / $5 |
The picture got simpler in September. At the top (GPT-6 Astra vs Fable 5.1) and in the middle (GPT-6 Sol vs Sonnet 5), input and output prices are identical. Opus 5.5 ($4/$20) has no same-priced GPT-6 counterpart, so it sits between those two bands; in the light band, GPT-6 Luna costs a tenth of Haiku 4.5. OpenAI says GPT-6 Sol and Luna are priced 50% below GPT-5.6 Sol and Luna. For a closer look at the top band, see GPT-6 Astra vs Claude Fable 5.1.
Two reasons not to compare on sticker price alone
- Tokenizers differ. The same text turns into a different number of tokens depending on the company and model. Anthropic notes that the tokenizer in Claude 4.7 and later models produces roughly 30% more tokens for the same text. Running the same job on both and comparing the bill is more accurate.
- Long inputs are billed differently. Anthropic bills the full 1M-token window at standard rates on Claude 4.6 and later models. OpenAI's pricing docs list separate long-context rates for the GPT-6 family (for example, Astra at $20 input / $75 output), so very long documents change the math.
The workload matters too. Feeding in a long document for a short summary is input-heavy; generating long code or verbose answers is output-heavy. Before you commit, check the OpenAI pricing docs and the Anthropic pricing docs.
Top models can also change for policy reasons
Anthropic's Claude Fable 5, released on June 9, 2026, was suspended on June 12 to comply with US Department of Commerce export controls, and access was restored on July 1 after the controls were lifted on June 30 (Anthropic's statement). Its successor, Fable 5.1, followed on September 1.
The practical takeaway: whether a top model is available can change for policy reasons, not just technical ones. If your work depends heavily on one specific model, keep a fallback ready.
Which to use when
- Coding, long documents, long-form writing, a terminal coding agent → Claude tends to fit
- You need pictures or photos generated → ChatGPT (or a dedicated image tool)
- Voice chat and web search → both work; stick with whichever you already use
- API cost → top and mid bands are priced the same, so compare real token usage on your own tasks
A three-step way to compare them yourself
- Pick two or three tasks you do often — for example, summarizing meeting notes, drafting a report, or fixing a small piece of code.
- Give both free plans the exact same prompt and the same files. Differences only show up when the conditions match.
- Judge the results on accuracy, how many fixes you needed, and time spent. A few days of real use tells you more than one or two tries.
Both are free to start, so this is the most reliable test. You don't have to pick just one, either — see using Claude as your main agent alongside other AI tools.
FAQ
Is Claude better than ChatGPT?
Neither is better across the board, and there's no official ranking. Claude is often cited for coding, long documents and building deliverables; ChatGPT is the one to pick if you need image generation. For coding specifically, both companies ship coding agents (Claude Code and OpenAI's Codex) — see Claude Code vs Codex.
How is Claude different from ChatGPT?
Different makers (Anthropic vs OpenAI) and different handling of images: ChatGPT generates images, while Claude produces diagrams, charts and SVG visuals rather than photos or illustrations. Both offer voice chat and web search.
Can I use Claude and ChatGPT for free?
Yes. Both have a free plan, with limits on usage and on which models you can use. For Claude's free limits, see the Claude free plan guide.
Can Claude generate images like ChatGPT?
Not photos or illustrations. According to Anthropic's help center, Claude doesn't generate images the way image-generation tools do, but it can create diagrams, charts and interactive visuals in HTML and SVG, and it can analyze images you upload.
Which API is cheaper, Claude or OpenAI?
As of September 27, 2026, the top band (GPT-6 Astra and Fable 5.1, $10/$50) and the mid band (GPT-6 Sol and Sonnet 5, $2/$10) cost the same per million tokens, and GPT-6 Luna is cheaper than Haiku 4.5 in the light band. Tokenizers and long-context billing differ, though, so compare the actual bill on the same workload.
Summary
Claude and ChatGPT are less about a winner and more about matching the tool to the job. If you need pictures, use ChatGPT; if your work centers on code, long documents or building deliverables, try Claude first — and settle the rest by running the same tasks on both.
