What each AI actually is
Claude is Anthropic's assistant. The current lineup, per Anthropic's models overview, is Claude Fable 5.1 (for the most demanding reasoning), Claude Opus 5.5 (released September 22, 2026 and Anthropic's recommended starting point), Claude Sonnet 5 (June 30, 2026, the fast daily model and the default on Free and Pro) and Claude Haiku 4.5. Opus 4.7 and Sonnet 4.6 are now legacy models.
ChatGPT is OpenAI's assistant. GPT-6 Astra is the flagship, with GPT-6 Sol and Luna added on September 22. In everyday Chat, paid plans run GPT-5.6 Sol with a thinking slider, Free and Go run GPT-5.6 Luna, and Astra appears as GPT-6 Pro on the Pro plans, per OpenAI's ChatGPT model guide. ChatGPT still has the broadest feature set: voice, image generation, deep research, ChatGPT Work, Codex and memory.
Pricing
Claude (Anthropic), per Claude pricing:
- Free: Sonnet and Haiku models, web search, file creation, memory
- Pro $20/month ($17/month billed annually): Opus, Sonnet and Haiku, Claude Code, Research, Projects, Claude in Chrome
- Max from $100/month: choose 5x or 20x Pro usage per session, higher output limits, priority access
- Team and Enterprise: per-seat plans with admin controls, SSO and, on Enterprise, usage billed at API rates
- API: Opus 5.5 at $4/M input and $20/M output; Sonnet 5 at half that
ChatGPT (OpenAI), per ChatGPT pricing:
- Free: unlimited everyday text chats on GPT-5.6 Luna, may show ads
- Go $8/month: more uploads, images and memory, may show ads
- Plus $20/month: GPT-5.6 Sol with thinking levels, GPT-6 Astra in ChatGPT Work and Codex
- Pro $100 (5x Plus) or $200 (20x Plus): GPT-6 Pro in Chat. New $200 sign-ups are paused since September 10, 2026
- API: GPT-6 Astra at $10/M input and $50/M output; GPT-6 Sol at a fifth of that
Consumer entry pricing is identical (prices verified on both vendors' pages as of September 2026). On the API, the flagships differ sharply: Opus 5.5 costs 40% of GPT-6 Astra per token. The mid-tier models, Sonnet 5 and GPT-6 Sol, are priced identically.
When Claude wins
Writing quality. This is Claude's most consistent advantage in our daily use. Claude's prose reads more like a careful human editor and needs less rework before it goes to a client. It holds brand voice across long documents and edits without flattening the author's style.
Long-document analysis in the app. Paste an 80-page PDF and ask for every commitment the CEO made in an earnings call. Claude's paid plans offer a context window of up to 1M tokens depending on the model, while ChatGPT Plus lists 54K tokens for Instant and 256K for reasoning on its pricing page. For long documents inside a consumer chat, Claude holds several times more.
Instruction-following. When you say "no passive voice," "exactly 200 words" or "match this code style," Claude follows the constraint more reliably, including on the second and third pass of the same prompt.
Professional and long-form writing. Legal documents, executive briefs, technical specifications and research synthesis, anywhere one off-tone sentence is unacceptable. Claude's careful tendency makes it the safer pick for high-stakes output.
Knowledge work at a lower flagship price. Anthropic's Opus 5.5 launch table reports 1846 on GDPval-AA (professional knowledge work) against 1542 for GPT-6 Astra, and 67.7% vs 57.2% on Humanity's Last Exam. These are Anthropic's own measurements, but they come with a price that is 60% lower per token.
Artifacts, Design, Slides and Docs. Claude generates editable documents, code and diagrams in a side panel, and Pro adds Claude Design, Slides and Docs for finished deliverables.
When ChatGPT wins
Voice. ChatGPT Voice can now call GPT-5.6 or GPT-6 Astra for harder questions and use plugins mid-conversation, according to OpenAI's release notes. Claude has voice mode on every plan, but ChatGPT's is more complete for hands-free work.
Image and video. ChatGPT generates images natively, and OpenAI's Sora handles video. Claude has no native image or video generation.
GPT-6 Astra for hard reasoning and computer use. OpenAI publishes 98% on FrontierMath Tier 4 and 99.9% on ARC-AGI-3 for Astra. On Anthropic's own table, Astra edges Opus 5.5 on AutomationBench (41.4% vs 40.0%). For math-heavy research and long computer-use tasks, Astra is worth testing, though in Chat it needs a Pro plan.
Office integration. ChatGPT now works inside Word on every plan and has Excel and PowerPoint add-ins. Claude also has Microsoft 365 integration on Pro, but ChatGPT's reach into everyday apps is broader.
Broader ecosystem. ChatGPT connects to a long list of apps through plugins and connectors. Claude's integration footprint is growing but smaller.
A note on custom GPTs. These used to be a ChatGPT advantage. In September 2026, OpenAI announced plans to retire custom GPTs and migrate them to plugins, so they are no longer a reason to pick ChatGPT on their own.
Real-world use cases: which to pick
Use Claude when:
- You write professionally (essays, briefs, legal, journalism)
- You analyze long documents (50+ page PDFs, contracts, research papers) inside the chat app
- Your work requires careful instruction-following (legal, financial, regulatory)
- You want fewer "AI tells" in client-facing output
- You code with focus on multi-file refactoring and large codebases
- You want a flagship API model at a lower price per token
Use ChatGPT when:
- You use voice regularly
- You generate images or videos
- You want OpenAI's GPT-6 models for math or computer-use tasks
- You work in Word, Excel or PowerPoint all day
- You want one tool that covers the most features
Benchmark snapshot (September 2026)
The only published table that puts both flagships side by side comes from Anthropic's Opus 5.5 launch post. Treat it as vendor-reported.
| Benchmark (Anthropic-reported) | Claude Opus 5.5 | GPT-6 Astra |
|---|---|---|
| Terminal-Bench 4.0 | 66.4% | 57.9% |
| FrontierCode v1.1 | 54.4% | 53.3% |
| GDPval-AA v2.1 | 1846 | 1542 |
| AutomationBench | 40.0% | 41.4% |
| Humanity's Last Exam | 67.7% | 57.2% |
OpenAI's own launch post reports different evaluations for Astra (FrontierMath, ARC-AGI-3, OSWorld) and does not include Opus 5.5. The honest reading: both are frontier models, Claude leads on most of Anthropic's chosen tests, and your own prompts are the benchmark that matters.
