A comparison guide: ChatGPT vs Gemini vsClaude AI recent models. Let's focus on functionality, performance, cost, and security.
Hello, I'm Artem and I've been using all three of those most popular AI models for a long time. If you are not on a cutoff island, you surely know how fat AI has come. We now have multiple models that lead the way, and it may be difficult to understand, which one to use and when. So it may be useful and insteresting to compare. Among those top AI models today are ChatGPT with GPT4o from OpenAI, Gemini 2.5 from Google & Claude 4 from Anthropic. This detailed guide will explore their functionality, performance and cost. I also dive into some security features, and how to compare all those models independently.
What will we explore? Functionality. Performance. Then, cost. Security. How to compare AI models by yourself. And multi-AI model use with Writingmate, which is all-in-one AI tool that lets you use all of those models for much better price. So, let's start!
Features and Capabilities
ChatGPT by OpenAI
ChatGPT is probably the most known AI model (and chatbot). It was designed by OpenAI. It can be used for many purposes, from writing articles to answering questions and aiding in coding. The latest version, GPT-4o, was much improved in contextual understanding, it (generally) gives you more coherent responses. There is also GPT-4o Mini with a reduced price and a set of cool features.
Example Uses:
Content Creation: ChatGPT can help writers by generating ideas, drafting articles, or even writing complete essays, that said, it is easy to know when it was not human writing the text.
Coding Assistance: Developers can use ChatGPT to fix bugs in the code, generate code snippets, or to troubleshoot problems.
Customer Service: Businesses can automate responses to customer inquiries, providing quick and accurate support.
Gemini by Google
Gemini version 2.5 by Google works best for real-time conversation. It gives rapid responses and maintains the context of long conversations, making it perfect for customer service chatbots.
Example Uses Include:
Customer Support: Companies use Gemini for multiple years, it helps them work over hundreds of customer inquiries and resolve issues instantly. Some users find it useful, some users hate those AI assistants… But, either way, Gemini changed customer support forever and I have some respect to it just for that.
Interactive Applications: Gemini can help financial advisors who need interactivity on the spot, with some live assistance and advice.
Personal Assistants: Gemini can manage schedules, also set reminders, and perform tasks that require conversations and answers on a larger scale.

Claude by Anthropic
Claude 4 Sonnet, asides from being quite a capable model, also focuses on safe and ethical AI usage. It is designed to avoid harmful or biased responses. This is why Claude became quite a standard for educational and sensitive applications, even though many schools and universities ban Claude. Writingmate helps to use new Claude 4 without those bans and with much less limits, in any country and with a lot of document, research and studies oriented features.
Example Uses of Claude 4 Sonnet in 2025:
Educational Tools: Claude can help students with their studies to make texts that will be safe and appropriate.
Mental Health Support: Claude can provide mental health advice while carefully avoiding triggers or harmful suggestions.
Ethical Chatbots: Use Claude for coding or for tasks where safety and ethics are in top priority. I would say law or healthcare are also things that Claude works well with.
Performance
In this section, we will see some benchmarks and information on actual perfomance of those modes. I have analyzed this and want to share some insights.
ChatGPT
ChatGPT is known for its high performance, thanks to extensive training on diverse data. It can handle a wide range of queries accurately. The GPT-4o Mini version is a lighter, faster model ideal for applications that require quick responses. And now there is also OpenAI's new o1 model that is great for calculations, math and something like coding.
Example Performance:
Newsrooms: Journalists can use ChatGPT to draft articles quickly. That makes their job more productive, less monotonous but also gives some challenges to overcome.
Coding: Developers benefit from its fast and accurate coding suggestions, especially with something like ChatGPT o1 model or Gemini 2.
Customer Service: Automates and enhances customer interactions with precise and quick responses.

Gemini
Gemini 2.5 is great when it comes to real-time communication. It is being made by Google (earlier naming the model Bard), and there are also Pro and Flash versions available. It is good at maintaining conversation context over extended periods of time. This may give a significant advantage in customer support and advisory roles, but also on day-to-day level. Who wants to constantly remind that chatbot all the details you "fed" it before? Better to remember everything and to generate based on that.
Example Performance:
Financial Advising: Assists in giving accurate and timely advice when having client conversations.
Customer Interaction: Handles multiple customer queries simultaneously with minimal response time.
Live Assistance: Suitable for applications requiring continuous and dynamic interaction.

Claude
Claude 3.5 Sonnet may not be the fastest (in my experience), but its focus on ethical responses and on consistent quality is unparalleled. It makes any interaction safe and balanced. In my opinion, Claude is probably an easiest model to avoid any harmful content. Keep in mind that there are also several versions of this model avaliable, for example, Claude Sonnet 3.5!
Example Performance:
Mental Health Chatbots: Provides safe and supportive responses for users seeking mental health advice.
Educational Platforms: Ensures educational content is free from harmful biases.
Legal Assistance: Offers reliable and ethical advice, avoiding any controversial statements.

Free vs Paid
Let me now show you some insights on pricing. What I have found may surprise you and save you quite a budget.
ChatGPT
The pricing for ChatGPT ranges widely, from free versions with limited features to the advanced GPT-4o with a premium price tag. The cost reflects the model's extensive capabilities and high performance.
Pricing Examples:
Free Edition: Limited features, suitable for casual users or small-scale applications.
Premium Packages: Higher prices justified by advanced features, suitable for businesses needing high performance and versatility. You can see the recent list of plus and team features:

Gemini
Gemini 2.5 Pro offers multiple subscription plans catering to different needs, from small businesses to large enterprises. The competitive pricing is balanced considering its advanced conversational features.
Pricing Examples:
Basic Plan: Affordable for small businesses looking for efficient customer service solutions.
Pro or Enterprise Plan: More expensive, suitable for large organizations requiring extensive use of the model.

Claude
Claude 3.5 Sonnet is priced higher due to its emphasis on ethical and safe AI use. Its cost may seem steep, but it provides peace of mind for users prioritizing responsible AI.
Pricing Examples:
Premium Pricing: Justified by the assurance of ethical interactions, suitable for organizations where safety is a critical concern.
Educational Discounts: Potential discounts for educational institutions focusing on safe AI interactions.
Here is Claude 4 Pricing as of Summer 2025.

Security
Security is one more important parameter to compare in AI models, and here are some nuances to all three models.
ChatGPT
ChatGPT emphasizes data security because it has one of the best protocols to protect user privacy, and quite a lot of options in the settings. To me, it is not always sufficient, so I would say that you better follow best practices from this video:
Security features of this chatbot include data encryption, it (mostly) protects user data from any unauthorized access. There is some user anonymity to GPTT: it makes sure user interactions are private and secure, and some compliance with regulations as well.
Gemini
Gemini 2 employs advanced encryption methods and they seem to be consistent with Google’s security standards. Is this reliable enough? Will it keep your sensitive information safe? I will let you decide on that, but personally did not have problems with Gemini and most of Google's services.
Security Features here include:
Advanced Encryption: Protects sensitive data, f.e. medical or financial information.
Dual Authentication: Adds one more layer of security for user accounts and ties well with Google infrastructure if you use one.
Regular Security Audits: Hints at a "continuous improvement of security protocols".

Claude
Claude is a bit different. Anthropic has always said that that it is committed to ethical AI use. They seem to have some inbuilt safety features that prevent misuse better, and ensure secure interactions on many levels.
Security Features:
Harm Prevention Algorithms: Prevents the generation of harmful or biased responses.
Ethical Guidelines: Ensures all interactions adhere to ethical standards.
Regular Updates: Frequent updates to address potential security vulnerabilities.

FAQ
I will now answer 6 questions I often get about those three models and about GPT vs Claude vs Gemini comparison.
Q: ChatGPT vs Gemini vs Claude – which AI is the most powerful in 2025? A: They are all powerful in different ways. OpenAI’s ChatGPT (GPT-4/4.5) is great for many tasks and shows creativity. Google’s Gemini 2.5 shines in interactive chats and accessing current information. Anthropic’s Claude 4 is best for safe, in-depth reasoning and coding. I think there’s no one winner.
For pure coding tasks, Claude 4, especially the Opus model, is often best.
For quick conversations, for more of up-to-date info, Gemini is often better in my experience.
If you need problem-solving with creativity, strangely, GPT works well enough, and so do models like Grok.
Still, many think GPT-4 (ChatGPT) & Gemini are more or less equal in general intelligence. Claude is in my experience also close but focuses more on safety.

Q: Is Google Gemini better than ChatGPT for general use? A: Gemini is great if you often need real-time info or Google tools. For example, if you need AI to help with emails, summarise web pages, or provide the latest news, Gemini (via Google Bard or Workspace) is very effective. ChatGPT might be better for open-ended creative tasks or if you want to use the many plugins available. For most everyday questions or writing tasks, both will serve you well.
Some people prefer ChatGPT’s style of answers, while others prefer Gemini’s. The good news is both have free versions (ChatGPT has a free tier & Google Gemini / Bard is free), so you can try each and see which fits your style.
Q: Is Claude safer to use than ChatGPT or Gemini? A: Claude is generally the most restrictive and safety-focused. It’s less likely to produce disallowed or risky content due to its constitutional AI design.
If you ask the same sensitive question to all three, Claude will likely give a cautious answer or refuse if it’s too much. ChatGPT and Gemini, while also cautious, may try to answer a bit more readily.
All three have safety filters. However, Anthropic is known for prioritising ethics and being less in general scale, which lets it center on things that other model developers often don't.
Some users and businesses that can't afford mistakes often prefer Claude. In short, yes, Claude somehow be considered “safer” in its default behavior. That said, OpenAI and Google have strong safety teams too. Yet, to my experience, none of them are prone to wild outputs in normal use.

Q: Claude vs Gemini, which one is free to use? A: Both have free access in some form. Claude can be tried for free on claude.ai (you may need to sign up, and there are usage limits for free accounts). Gemini powers previously famous Google’s Bard, which was also free to use for anyone with a Google account.
Using the full models: Gemini's advanced features, such as some Gemini Pro capabilities, may need a subscription or Google One membership.
For instance, Gemini 2.5 “Advanced Mode” is now available with Google One Premium. Claude’s latest model (4 Sonnet) is available free in limited usage with a lot of caps and limits. But heavy users would need a Claude Pro subscription or pay-as-you-go via API.
No such thing on Writingmate, you pay single subscription that is most often 9 dollars, and you get most of the best AI models in one chatbot. It includes Claude 4 Sonnet, GPT4o, new Gemini, Mistral, Llama 4, and more advanced options as well. Try it for free.
So, for light or personal use, you can access both without paying. For enterprise or extended use, both offer paid options. You can choose Claude’s API or an Anthropic subscription, and Gemini is available through Google Cloud services.
Q: Which AI model is best for coding assistance in 2025?
A: All three work well for coding, but each has its sweet spot.
ChatGPT (GPT-4) is what most developers reach for first. It's great at explaining messy code and works with tons of programming languages. Plus it integrates nicely with VS Code and other tools you're already using.
Claude 4 Opus does the big stuff best, it refactors entire codebases, debugging complex projects, working with multiple files at once. Its memory is solid, so it won't forget what you talked about three prompts ago.
Gemini 2.5 does coding challenges and algorithmic problems well enough and often better than models like Deepseek R1 or GPT models. I know Google's been showing it off on leaderboards for good reason. It's especially good if you're working with Google's ecosystem that also expands.
Most developers I know use ChatGPT for quick questions and Claude for heavyweight tasks. Some check one against the other when they're not sure about an answer. If you're doing Google Apps Script or cloud APIs, try Gemini. For everything else, start with ChatGPT and switch to Claude when things get complicated. You can use all of those models on Writingmate.ai for better price, with less limits and with a bunch of additional features.
Q: Will there be a GPT-5 or Gemini 3 soon? A: As of July 2025, GPT-5 is not released yet. OpenAI has hinted they’re working on it, but there’s no official release date. Rumors suggest it could be late 2025 or 2026. In the meantime, OpenAI gave us GPT-4.5 as an intermediate update. Gemini 3 hasn’t been announced yet either. Google already has Gemini 2.5, and they typically iterate (maybe Gemini 3 could be in development and out in late 2025 or early 2026). It wouldn’t be a surprise if, in a year, we hear about next-gen models from OpenAI and Google. Anthropic is also likely to be working on Claude 5 though no actual news are available on this as of today. For now, the current versions we discussed are the latest publicly available. I would say, watch for official announcements. When the next-gen model arrives I would like to also cover it on this blog.

For instance, a multimedia content creator could use ChatGPT for scriptwriting and Claude to ensure the script is ethical and unbiased. In the same tim Gemini talks to yur audience in real-time for feedback and live sessions.

Conclusion
Each AI model, ChatGPT, Gemini, and Claude, are different and each model has its own personality, best use cases and top capabilities. ChatGPT 4o works well for most everyday tasks, to me it's like the Swiss Army knife of AI. Gemini Two shines in live conversations, which is why customer service teams love it. Claude Sonnet plays it safe with responses, perfect when you need something reliable for work stuff. Then you've got models like o1 and DeepSeek that do specific things really well, but that's a rabbit hole for another day.
Want to see how these models do stack up best? I recommend to visit ChatbotArena. It's this cool site where you can test two models head-to-head without knowing which is which. They also have solid leaderboards that show what's actually winning right now.
Here's the thing - Arena and WritingMate solve different problems. Arena is great for comparing models and seeing who's on top. WritingMate is what you use when you just want to get work done with access to all the good models in one place.
