Short answer: Claude performs better for careful long-form writing, analysing long documents and agentic coding with Claude Code. Grok performs better when you need real-time information from X and the web, a more casual personality, and built-in image and video generation through Grok Imagine. Both have free plans. Grok’s paid plans start at $8 a month; Claude’s start at $20 ($17 billed annually). Your choice should depend on the work, not the headlines.

Who makes them
Claude is built by Anthropic, an AI safety and research company. Grok is built by xAI, the AI company founded by Elon Musk, which became part of SpaceX in February 2026. For the background story, read Elon Musk, xAI and the AI industry and what is Grok AI.
The models
Claude 5.5 family
Anthropic launched Opus 5.5 on September 22, 2026, with a 1-million-token context window, up to 128,000 output tokens and always-on adaptive thinking. Sonnet 5.5 followed on September 28 and Haiku 5.5 on October 7. Fable 5.1 is Anthropic’s top model for long-running agents (Claude Platform release notes, Anthropic).
Grok 4.7
xAI describes Grok 4.7 as its “flagship model for code and everything else”, with agentic tool calling, configurable reasoning and a 500,000-token context window. Its stated knowledge cut-off is May 2026, which is why its live search matters (xAI docs).
Our take: both are frontier-class. Public benchmark rankings shift with every release, and we haven’t run independent lab tests, so we compare what you can actually see and use.
Performance by task
| Task | Better choice | Why |
|---|---|---|
| Long-form articles and reports | Claude | Natural tone, strong consistency with style guides |
| Breaking news and trending topics | Grok | Real-time access to X posts and the web |
| Summarising a 300-page PDF | Claude | Up to 1M-token context and PDF support up to 1,000 pages |
| Agentic coding on a real repository | Claude (test both) | Claude Code is a dedicated agent; Grok paid tiers bundle Cursor |
| Images and short videos | Grok | Grok Imagine is built in |
| Casual, witty conversation | Grok | Designed with a more irreverent personality |
| Cautious answers on sensitive topics | Claude | Anthropic’s safety focus |
| Voice chat | Tie | Both offer voice modes |
Writing
Claude’s default writing reads as calm and natural, and it rarely ignores formatting instructions. Grok writes quickly and is good for punchy social posts, especially for X. For long, polished content, most writers will prefer Claude. See how to use Claude AI for professional writing.
Real-time information
This is Grok’s biggest advantage. It can pull in what people are posting on X right now, alongside web results, which is useful for news, markets chatter and trends. Remember that posts on X are not verified facts. Our guide to Grok’s real-time information from X explains how to use it carefully.
Coding
Claude Code runs in the terminal, VS Code, JetBrains, the desktop app and the browser, and can read your codebase, edit files, run commands and open pull requests (Claude Code docs). xAI positions Grok 4.7 as its main coding model, and paid tiers of The X Subscription include Cursor with a shared Grok usage pool (x.ai). Read what is Claude Code for details.
Images and video
Grok Imagine creates images and short videos from prompts. Claude can build charts, diagrams and interactive Artifacts with code, but Anthropic’s plan pages don’t list a photo-style image or video generator. See what is Grok Imagine.
Strengths and weaknesses at a glance
| Claude | Grok | |
|---|---|---|
| Biggest strength | Careful writing, long documents, coding agents | Live X and web data, images and video |
| Biggest weakness | No live social data; free limits can run out on long chats | X posts can spread unverified claims; style can be too casual for formal work |
| Best for | Professionals, writers, analysts, developers | News followers, creators, social media teams |
| Watch out for | Confident errors on niche facts | Confident errors on fast-moving stories |
A simple rule of thumb: if the cost of a mistake is high (contracts, tax, health, money), use the tool that lets you work from documents you trust and check every claim. If speed and awareness of what is happening right now matter most, Grok’s live feed is hard to beat, but treat it as a starting point for verification rather than a final answer. Neither tool is a substitute for a qualified lawyer, accountant or financial adviser.
Pricing compared
| Tier | Claude | Grok (The X Subscription) |
|---|---|---|
| Free | $0 | $0 |
| Entry | Pro $20 ($17/month annual) | Plus $8 |
| Mid | n/a | Premium $30 |
| High | Max $100 | Super $100 |
| Highest | Ultra $200 | Ultra $200 |
| Teams | Team from $20/seat (annual) | Business options via xAI |

Grok’s paid tiers also bundle X Premium features and Cursor. Claude Max and Ultra include monthly API credits ($100 and $200) for building on the Claude Platform. If you’re comparing free tiers, see is Grok AI free? and Claude Free vs Pro.
Both companies list prices before tax, so expect VAT or sales tax depending on your country, such as 20% VAT in the UK (GOV.UK) or 5% VAT in the UAE (FTA).
Privacy and safety
Anthropic lists model training as opt-out on its individual plans and off by default for Team and Enterprise (Claude pricing). Grok is tied closely to X, and its real-time features draw on public posts. With either tool, review the privacy settings, avoid sharing personal identifiers or client data, and follow UK GDPR or EU GDPR where they apply (ICO).
For businesses
Claude’s Team plan supports 2 to 150 seats with SSO, admin controls and shared projects, and Enterprise adds SCIM, audit logs and custom retention (Claude Help Center). Grok’s business options are covered in Grok AI for business. For practical ideas, see how businesses can use Claude AI to save time.
Which should you choose? Real scenarios
A US day trader following market sentiment: Grok, for real-time X chatter, but cross-check with official filings and never trade on a post alone.
A UK solicitor’s office summarising long documents: Claude Team, for long context and business data controls, with a human reviewing every output.
A Canadian YouTuber needing thumbnails, short clips and scripts: Grok for visuals, possibly Claude for scripts.
An EU software team: Claude Code trial on a real repository, compared against Cursor with Grok.
A UAE content agency writing bilingual copy: test both; check Arabic quality with a native speaker.
