Claude 4 vs ChatGPT: Which AI assistant is right for you?
Whether you're looking for a creative collaborator, a coding partner or an all-in-one productivity tool, knowing how they compare can help you choose the right one for your style and needs.
I've been testing AI chatbots for years, so let me break down the ChatGPT vs Claude differences that you need to know.
While many users are eagerly anticipating the release of ChatGPT-5, OpenAI's current flagship model is GPT-4o (short for 'Omni'), and the company's most advanced base model to date. It supports multimodal input and output, meaning it can understand and respond to text, image, and audio, and it enables real-time interactions, including natural voice conversations and image generation.
Anthropic's Claude 4, released in May 2025, comes in two versions. Claude Sonnet 4 is the free, fast, general-purpose model built for everyday use, while Claude Opus 4 is a premium model designed for deep reasoning, advanced coding tasks and large-scale context handling.
It's built to power more complex workflows and long-form problem-solving.
ChatGPT is available on the web, iOS and Android, and it's tightly integrated into Microsoft's ecosystem through Copilot in Bing, Word, Excel and other Office apps.

Claude 4, meanwhile, is accessible via claude.ai on the web, iOS and Android.
Developers and enterprise users can also access Claude via the Anthropic API, as well as through platforms like GitHub Copilot, AWS Bedrock and Google Cloud's Vertex AI.
ChatGPT, powered by GPT-4o, offers strong conversational memory and supports multimodal input, including text, images, audio, file uploads and code execution. Users can personalize interactions with memory settings and even build custom GPTs for specific tasks.
Although Claude does not have a memory feature, Claude 4 supports up to 200,000 tokens of context, allowing it to handle and retain significantly more information in a single conversation; the equivalent of more than 500 pages of text.
ChatGPT offers fast, responsive performance and is particularly strong when paired with tools like Microsoft Copilot. Its reasoning abilities are enhanced by plugins, file uploads, and its new Agent feature, which can browse the web, execute tasks and automate workflows across apps.
Claude Sonnet is similarly fast and excels at maintaining depth and continuity in conversations, making it a strong writing partner or analytical assistant.
Claude Opus takes things further with support for multi-hour workflows, legal reasoning, code explanation and complex research tasks. On industry benchmarks like SWE-bench, Claude Opus ranks among the top performers for software engineering use cases.
When it comes to multimodal support, ChatGPT offers more with in-chat image generation, visual context and real-time voice conversations with memory.
Claude supports image input and visual understanding, meaning users can upload an image and the chatbot will assist with comprehension, but it cannot generate images. Also, Claude does not offer real-time conversational chat.
Claude 4, especially in its Sonnet form, stands out for its natural, thoughtful tone. It often feels more like a helpful assistant offering clear explanations, thoughtful suggestions and a calm, conversational flow. If you're writing, brainstorming or trying to make sense of something complex, Claude tends to feel more human in how it engages.ChatGPT is professional, polished and highly adaptable, with the ability to shift tones based on a user's preference or task. It is arguably more chatty than Claude, which appeals to some users more than others.
ChatGPT supports a broad set of integrations including custom GPTs, an extensive plugin ecosystem, and Microsoft Copilot.
Its new ChatGPT Agent feature (currently in early access) allows it to take real action on your behalf: browsing the web, interacting with forms, generating presentations and more all within a secure sandboxed environment.
Claude 4 doesn't yet offer a native agent feature through its user interface, but it does support tool use and extended workflows through its API. It also integrates with GitHub Copilot, AWS Bedrock and other developer platforms, making it a strong option for those building their own agentic systems.
If you're looking for an all-in-one AI assistant, ChatGPT is the more versatile choice. It can speak, see, listen, browse, generate images, analyze documents and automate tasks. Its voice mode feels remarkably human and is useful for a hands-free experience. The chatbot's ability to create and understand images adds another layer of functionality that Claude doesn't natively support.
ChatGPT also integrates seamlessly with Microsoft products and lets users build custom GPTs tailored to their specific needs. And for power users, the new ChatGPT Agent adds another level of autonomy and actionability that's unmatched in most other consumer-facing AI tools.
Claude 4 shines in natural language understanding and thoughtful conversation. It's ideal for users who prioritize clarity, warmth and coherence in writing, editing and reasoning.
Whether you're crafting long-form content or analyzing dense documents, Claude delivers consistently thoughtful and easy-to-follow responses.
Its 200K-token context window makes it the better choice for handling long inputs like research papers or legal contracts. Claude Opus, in particular, is built for high-stakes reasoning tasks and delivers top-tier performance for technical, legal and academic work.
Even better, Claude Sonnet 4 is free, making it an excellent entry point for users who want fast, capable AI without paying for a subscription.
Both ChatGPT and Claude are chatbots that I use every day. But they serve different goals.
ChatGPT is my go-to for versatility, real-time interaction and multimodal tasks while Claude is what I use most often for summarizing, reasoning, deep context and analytics.
Knowing what each excels at can help you choose the right assistant, or mix and match based on what you're trying to accomplish.
Which chatbot do you prefer and why? Let me know in the comments.

Microsoft becomes the second $4 trillion company
Microsoft's stock price has risen so much today that it has passed a $4 trillion market valuation for the first time in its 50-year history. The software maker is the second company to be valued at $4 trillion, after Nvidia reached a market cap of over $4 trillion earlier this month. Microsoft has reached this milestone thanks to better-than-expected earnings, and the company reporting its Azure revenue for the first time. Microsoft revealed last night that its Azure cloud computing business had generated more than $75 billion during its 2025 fiscal year, and the company's stock price immediately started soaring in after-hours trading on the Nasdaq. Microsoft's share price is up around 4 percent today, helping it maintain its $4 trillion market valuation. Microsoft has spent more than a decade building up its Azure cloud business, which is ahead of Google's in revenue but still second place to Amazon Web Services. Azure now touches every corner of Microsoft's businesses, including powering its AI projects, its Office software, parts of Windows, Xbox, and more. Microsoft's investment in cloud computing has positioned it well to take advantage of the computing needs for the future of AI, too. Earlier this year there were plenty of questions over the $100 billion investment into The Stargate Project, and Microsoft CEO Satya Nadella was quick to defend the company's own $80 billion spend on cloud and AI data center projects. 'All I know is, I'm good for my $80 billion,' said Nadella at the time. Microsoft CFO Amy Hood revealed yesterday that Microsoft is now planning to spend $30 billion on its AI infrastructure investments in the next quarter. If Microsoft keeps up that level of spending then the company will total $120 billion or more on cloud and AI infrastructure over the next fiscal year.

What is NordVPN's new Scam Call Protection feature?
NordVPN, which we consider to be the best VPN on the market, has expanded its digital safety tools to tackle phone-based fraud by rolling out a new Scam Call Protection feature. Now available in the NordVPN Android app for US users, the feature scans incoming calls for suspicious patterns and alerts users to potential scams before they pick up. It's designed to combat phishing, identity theft, and social engineering attacks – threats that cost US users over $16.6 billion in 2024, according to the FBI's Internet Crime Complaint Center (IC3). "We've always been about protecting people's digital lives, and phone scams are a huge part of that threat landscape now," said Mykolas Dumcius, NordVPN's Chief Product Officer, about the feature's rollout. NordVPN: our top-rated VPN overallNordVPN provides rock-solid security and privacy, excellent speeds and great unblocking performance making it the best VPN for pretty much everyone. Prices start from $2.91 per month for a two-year subscription, which includes an exclusive four months free for Tom's Guide readers. Plus, you can even get an Amazon gift card worth up to $50 if you sign up for a two-year subscription to NordVPN's Plus or Complete memberships. You'll even get a 30-day money-back guarantee, so you can test it out, risk-free. The tool can run in the background while you use your phone, doesn't require the VPN to be connected, and works without accessing the content of any calls. Instead, it analyzes metadata using a privacy-first approach. Setup is simple: users can enable the feature from the "Threat Protection" tab within the NordVPN app, then follow the prompts to update their Android settings. Future updates will introduce caller ID for verified businesses, more detailed call categories (such as financial or healthcare services), and a community reporting system for suspicious numbers. Support for iOS and international markets is also in development. The feature is part of NordVPN's broader security suite, which includes Threat Protection Pro for blocking malware, trackers, and harmful websites. We test and review VPN services in the context of legal recreational uses. For example: 1. Accessing a service from another country (subject to the terms and conditions of that service). 2. Protecting your online security and strengthening your online privacy when abroad. We do not support or condone the illegal or malicious use of VPN services.

Your Microsoft Passwords Will Vanish in a Few Hours. What to Do Right Now
It's time to say so long to the Microsoft Authenticator app as we know it. As of this Friday, Aug. 1, the app will no longer save or manage passwords, use two-factor authentication or auto-fill. And it won't be your go-to password manager anymore, either. Instead of passwords, Microsoft is moving to passkeys -- such as PINs, fingerprint scans, facial recognition or a pattern on your device's lock screen. Using passkeys is a safer alternative to the risky password habits 49% of US adults use, according to CNET's password survey. However, Attila Tomaschek, a CNET software senior writer and digital security expert, prefers Microsoft's new login over password habits that can risk your data being stolen. There's not much time to learn about passkeys or password manager, but we're here to help. Here's what you need to know to get started. Microsoft Authenticator will stop supporting passwords on Aug. 1 Microsoft Authenticator houses your passwords and lets you sign into all your Microsoft accounts using a PIN, facial recognition like Windows Hello or other biometric data like a fingerprint. Authenticator can be used in other ways, such as verifying you're logging in if you forgot your password, or using two-factor authentication as an extra layer of security for your accounts. In June, the company stopped letting users add passwords to Authenticator. As of this month, you won't be able to use the autofill password function. And starting Aug. 1, you'll no longer be able to use saved passwords. If you still want to use passwords instead of passkeys, you can store them in Microsoft Edge. However, CNET experts recommend adopting passkeys during this transition. "Passkeys use public key cryptography to authenticate users, rather than relying on users themselves creating their own (often weak or reused) passwords to access their online accounts," Tomaschek said. Why passkeys are a better alternative to passwords So what exactly is a passkey? It's a credential created by the Fast Identity Online Alliance that uses biometric data or a PIN to verify your identity and access your account. Think about using your fingerprint or Face ID to log into your account. That's generally safer than using a password that is easy to guess or susceptible to a phishing attack. "Passwords can be cracked, whereas passkeys need both the public and the locally stored private key to authenticate users, which can help mitigate risks like falling victim to phishing and brute-force or credential-stuffing attacks," said Tomaschek. Passkeys aren't stored on servers like passwords. Instead, they're stored only on your personal device. More conveniently, this takes the guesswork out of remembering your passwords and the need for a password manager. How to set up a passkey in Microsoft Authenticator Microsoft said in a May 1 blog post that it will automatically detect the best passkey to set up and make that your default sign-in option. "If you have a password and 'one-time code' set up on your account, we'll prompt you to sign in with your one-time code instead of your password. After you're signed in, you'll be prompted to enroll a passkey. Then the next time you sign in, you'll be prompted to sign in with your passkey," according to the blog post. To set up a new passkey, open your Authenticator app on your phone. Tap on your account and select "Set up a passkey." You'll be prompted to log in with your existing credentials. After you're logged in, you can set up the passkey. Other password manager alternatives Since Microsoft will get rid of all of your passwords in two weeks, you'll need a new place to store your passwords safely. Tomaschek has a few of the best password manager recommendations after testing and reviewing several. The top recommendation is Bitwarden for its transparency. It's open-source and audited annually. From a price perspective, the free plan lets you store infinite passwords across unlimited devices. The free plan also includes features most password managers would charge for, including password sharing and a username and password generator. Bitwarden's upgraded plans have other upgraded features that could be worth the cost, too. Personally, Tomaschek has been using 1Password for a while, and he likes the interface and family plan. Even though it's second on the list, Tomaschek says it's just as good as Bitwarden.
