I Examined DeepSeek vs. ChatGPT within the Final AI Showdown

After I first heard about DeepSeek in January 2025, I assumed it is perhaps simply one other identify on the lengthy listing of ChatGPT options. I imply, I’d already seen many AI chatbots like Claude, Perplexity, and loads of others attempt to dethrone ChatGPT.

However one thing a couple of DeepSeek vs. ChatGPT matchup felt…. completely different. Primarily as a result of DeepSeek is totally free and absolutely open-source. That undoubtedly made me pause — and I wasn’t alone.

Since its launch, over 900 million individuals have visited the positioning, and greater than 301 million use it each month (myself included), in line with SimilarWeb knowledge. From GitHub stars to AI Reddit threads and Twitter/X buzz, DeepSeek has been all over the place currently.

Over the previous few months, I’ve been utilizing ChatGPT and DeepSeek facet by facet. And if you understand me, you already know I needed to run a correct head-to-head take a look at.

On this article, I’ll break down precisely how DeepSeek vs. ChatGPT performed out throughout real-world duties — writing, coding, summarizing, researching — and which one I’d truly suggest relying in your workflow. And sure, I’ve backed it up with G2 person knowledge too.

Fast be aware: “DeepSeek” is the identify of a complete household of open-source AI fashions, the chatbot interface that makes use of them, and the corporate behind all of it. After I point out “DeepSeek” right here,  I’m speaking in regards to the AI chatbot.

Be aware: Each OpenAI and DeepSeek regularly roll out new updates to those AI chatbots. The main points under mirror essentially the most present capabilities as of April 2025 however might change over time.

• AI fashions and processing energy: DeepSeek is constructed by itself open-source fashions, together with DeepSeek-V3 and DeepSeek R1, its reasoning mannequin. ChatGPT, alternatively, makes use of the generative pre-trained transformer (GPT) fashions. This contains GPT 4o mini for limitless chats within the free plan and restricted chats with GPT-4o, GPT 4.5, o1, o3 mini, o3-mini-high, and GPT-4 within the paid plan.
• Context Window:  The context window defines how a lot an AI can retain and reference in a single dialog. ChatGPT helps a 128,000-token context window, permitting for terribly lengthy conversations or multi-document duties. DeepSeek presents a considerable 64,000-token window, typically adequate for many makes use of, although smaller than ChatGPT’s prime capability.
• File dealing with: DeepSeek helps textual content, photographs, audio, video, and paperwork in numerous codecs like DOCX, PPTX, XLSX, CSV, and Google recordsdata. It may well deal with as much as 1,500 pages per file, 10 uploads directly, and 100MB per file. ChatGPT helps codecs like DOCX, PDF, TXT, PPTX, CSV, and XLSX, 512 MB per file, with free customers having three file uploads a day.
  
• Data cutoff: ChatGPT’s GPT-4 is educated on knowledge as much as December 2023. DeepSeek doesn’t formally disclose its information cutoff, making it much less clear in that space.
  
• Voice chat: ChatGPT wins right here for hands-free interplay with its built-in voice chat. It’s actually cool to speak on to it (downplaying right here — I adore it!) DeepSeek does not have that function proper now.
• Multimodal capabilities: ChatGPT is extra of a multi-sense AI. It may well perceive photographs (like charts), chat with voice, and even get a way of video. DeepSeek is basically robust with textual content and has turn into fairly good at understanding photographs and movies. Nonetheless, not like ChatGPT, voice interplay and picture technology aren’t at present commonplace options in DeepSeek’s predominant chat interface.
• Non permanent chats and sharing: ChatGPT is approach forward right here. It has short-term periods, chat historical past, and dialog sharing by way of hyperlinks. DeepSeek? None of that’s in-built. 
  
• Customized AI assistants: ChatGPT makes it simple to construct your personal customized AI helpers with reminiscence and instruments. DeepSeek does not supply a easy approach to do that; you’d have to be a developer to doubtlessly construct one thing your self on account of its open-source nature. ChatGPT is clearly extra accessible right here.
• Integrations: Once more, ChatGPT has a notable edge right here. Whereas each can hook up with many apps by way of companies like Zapier and Albato, ChatGPT additionally presents direct, built-in integration with Google Drive and permits one to attach with different apps. This makes it extremely simple to add and work together with your paperwork proper inside the chat. DeepSeek at present lacks this direct cloud storage hyperlink.
• Content material limitations: Now, relating to speaking about sure issues, like politics or something a bit sensitive, you may discover DeepSeek clams up a bit greater than ChatGPT. It would simply refuse to reply or offer you a very obscure response. ChatGPT undoubtedly has its personal filters, however it typically appears extra keen to speak a couple of wider vary of topics.
• Pricing: This can be a massive distinction. DeepSeek is totally free to make use of. You get all of the core goodies like net searches, entry to superior considering fashions, and file uploads with out hitting any paywalls. ChatGPT does supply a free choice, however if you would like the extra highly effective fashions and people further options like customized GPTs and better limits on chats, you will must shell out for ChatGPT Plus. So, if price is a significant factor, DeepSeek undoubtedly comes out on prime.

DeepSeek and ChatGPT: the similarities

No matter their variations, DeepSeek and ChatGPT even have lots in frequent. Right here’s what they each do effectively:

• Textual content technology: Whether or not that you must write a compelling story, summarize a prolonged article, or simply brainstorm some recent concepts, each DeepSeek and ChatGPT are extremely able to producing readable and related content material with comparatively little enter from you.
• Coding: Each of those platforms can function very useful coding assistants, whether or not you are making an attempt to debug current code, write new snippets, or just perceive complicated programming ideas.
• Internet search: Want to tug info from the web? Each have built-in net searching capabilities that can assist you discover what you are on the lookout for. 
• File evaluation: Bought a PDF, a Phrase doc, or another file that you must extract key insights from? You possibly can add it to both of those, they usually may also help you pull out the necessary info. It is an actual boon for analysis.
• Reasoning or considering fashions: In terms of considering issues by way of, each chatbots have upgraded brains — effectively, considering fashions. DeepSeek has DeepSeek R1 (aka DeepThink), whereas ChatGPT makes use of o1. Each are designed to deal with logic and complicated duties extra successfully.

Options are one factor, however how do these chatbots truly carry out? To seek out out, I examined them on 10 real-world duties.

Disclaimer: AI responses might range primarily based on phrasing, session historical past, and system updates for a similar prompts. These outcomes mirror the fashions’ capabilities on the time of testing. This evaluation is a person opinion and doesn’t mirror G2’s place in regards to the talked about software program’s likes and dislikes.

For this primary problem, I needed to see how effectively they may nail a concise abstract. I gave each ChatGPT and DeepSeek an article from G2 about how increasingly non-designers are utilizing Canva. Their mission was to boil it down to precisely three bullet factors and hold it below 50 phrases. 

ChatGPT gave me a well-rounded abstract that pulled in actual element from the article, together with G2 knowledge, Canva’s attraction to non-designers, and even talked about some drawbacks. It felt considerate and full — however right here’s the catch: it didn’t follow the phrase rely. It was undoubtedly over 50 phrases, which technically breaks the foundations of the immediate.

ChatGPT’s response to the summarization immediate

DeepSeek, alternatively, adopted the directions completely. It stayed effectively inside the phrase restrict, and its three bullet factors had been clear, structured, and simple to scan. The one snag I noticed was that the supply was not talked about.

So, who did it higher? Actually, it will depend on what you worth extra. Should you’re a stickler for format and readability, DeepSeek did precisely what I requested. However when you’re on the lookout for depth and helpful element, ChatGPT edged forward — even when it acquired a bit wordy. Personally, I’d give it to DeepSeek for immediate adherence.

Winner: DeepSeek

2. Content material creation

Content material creation is the place you see AI chatbots popping up all over the place lately. So, for this content material creation gig, I needed to see which AI may deal with a full-on advertising transient, from writing a product description and tagline to creating platform-specific posts and advert copy. And truthfully? Each DeepSeek and ChatGPT did a formidable job.

ChatGPT’s response to content material creation immediate

ChatGPT was all about that easy, polished vibe with a little bit of its personal character shining by way of. The product description simply flowed, the social posts felt like they had been able to go reside, and the tagline “Energy your telephone, energy the planet” was a kind of that sticks in your head with out being tacky. Its TikTok and YouTube concepts? Completely understood the platforms and had a very good tempo. The general tone was excellent – enjoyable however nonetheless clear. It felt like actual advertising materials you possibly can truly use.

The content material general felt a bit extra like a template, which is not essentially unhealthy, simply extra of a first-draft sort of really feel. 

DeepSeek’s response to the content material creation immediate

However, and it is a massive “however,” there was this one line in its TikTok script that simply utterly missed the mark for me. DeepSeek went with “useless telephone? by no means heard of her.” I get the place it was going for, however it simply sounded…ominous. 

So who received? So each did effectively, however ChatGPT will get the slight win for being extra inventive and brand-aware. Its output felt nearer to ready-to-publish. DeepSeek was stable however that one TikTok line? Undoubtedly getting lower. 

Winner: ChatGPT

3. Inventive writing

This was a enjoyable activity. I requested each bots to craft a 300-word science fiction story primarily based on a selected set of parts.

ChatGPT’s story “Whispers of the Wanderer” had regular, cinematic pacing that constructed rigidity organically. It felt tight, poetic, and confidently written, with simply sufficient world-building to spark your creativeness with out bogging issues down. The phrasing in locations, like “every swirl like a dwelling factor” or “partitions shimmering as if actuality itself frayed,” stood out as polished and evocative. And the twist landed laborious!

Then I learn DeepSeek’s model, “Echoes within the Nebula”. The writing was stable. The twist, whereas considerate, felt extra like a mild reveal than a real intestine punch. I felt the story delivered a extra emotionally satisfying and simply comprehensible story inside a traditional sci-fi framework.

4. Coding  

For the coding activity, I requested each chatbots to assist me construct a easy password generator utilizing HTML, CSS, and JavaScript.

DeepSeek nearly shocked me right here. Not solely did it let me run the code instantly contained in the chat (which was extremely handy), however it additionally included a password power checker. That further contact? I didn’t anticipate it, and it genuinely impressed me.

It made the entire expertise really feel a bit extra “developer-ready.” However then, simply as I used to be about to repeat the generated password, I hit a snag — the “Copy to Clipboard” button didn’t work. All the things else functioned easily, however that one piece broke the stream.

ChatGPT, alternatively, gave me a clear, absolutely practical model. I ran it in OneCompiler, and every little thing labored as anticipated — password technology, copying, and even a affirmation alert. It didn’t have the added power meter like DeepSeek did, however the code was dependable and plug-and-play.

5. Multilingual capabilities 

Given each the AI chatbots are multilingual, I used to be curious to see how effectively these may deal with translations past simply English. So, I tasked them with translating a easy English paragraph into Tamil, my native language.

Actually, each translations had been simply okay — not good, however serviceable.

ChatGPT’s model began robust. I truly most well-liked its phrase alternative for “fast,” which felt extra pure to me than DeepSeek’s. However the place ChatGPT fell a bit flat was within the third sentence; it felt a bit clunky and didn’t stream as effectively.

Translation by ChatGPT

DeepSeek, alternatively, did a greater job with that remaining line. It learn extra clearly and sounded smoother general. What additionally stood out was the additional context DeepSeek added. It defined the way it translated sure phrases like “pangram” and why it selected to transliterate a few of them. That sort of thoughtfulness undoubtedly added factors.

Translation by DeepSeek

Whereas neither translation blew me away, DeepSeek edged forward on this one. It wasn’t flawless, however it confirmed extra consideration to nuance and produced a barely extra polished outcome general.

Winner: DeepSeek

6. Picture evaluation 

I used to be curious how effectively these AI chatbots may deal with visible inputs, not simply plain prompts. Might they really have a look at a picture and provides me a transparent, helpful breakdown? To seek out out, I gave them two very completely different challenges: an infographic on AI adoption traits and a handwritten model of a traditional poem. I wasn’t after primary descriptions; I needed actual evaluation, construction, and insights that transcend the apparent.

ChatGPT truthfully nailed each duties. It broke down the infographic clearly, pulling out key stats and structuring them in a approach that made sense.

However what impressed me extra was the way it dealt with the handwritten poem. It precisely transcribed Emily Dickinson’s “Hope is the Factor with Feathers” phrase for phrase, even describing the fashion of handwriting and the paper it was written on. There was no confusion, no overthinking—it simply acquired it proper.

ChatGPT’s response to my picture evaluation immediate

DeepSeek additionally did effectively, particularly with the infographic. It didn’t simply extract the important thing factors; it gave me strengths, weaknesses, and suggestions for bettering the design. That was a considerate further step, and I appreciated the editorial lens. 

DeepSeek’s response to my picture evaluation immediate

However when it got here to the poem, it stumbled a bit. It misinterpreted the picture as a modified or barely inaccurate model of Dickinson’s authentic, assuming there have been spelling errors or intentional modifications — although the picture was a clear replica of the particular poem. So, whereas it acquired the gist, it layered on an interpretation that wasn’t actually true.

Winner: ChatGPT

7. File evaluation

For the file evaluation take a look at, I uploaded Einstein’s 1905 paper “On the Electrodynamics of Transferring Our bodies” and requested each chatbots to summarize the important thing findings in 5 bullet factors, below 100 phrases. I needed to see how effectively every one may distill dense tutorial content material into one thing readable and concise with out skipping the necessary stuff.

ChatGPT’s abstract was spot on. It lined all the correct rules, like relativity, fidelity of sunshine velocity, time dilation, simultaneity, and Lorentz transformations, with readability and construction. Every level was tight and accessible with out oversimplifying. Plus, the formatting and stream made it tremendous simple to comply with

ChatGPT’s response to the file evaluation activity

DeepSeek’s model wasn’t unhealthy in any respect! It hit most of the identical factors however it disregarded the fidelity of sunshine velocity, which is sort of a giant deal for particular relativity. That omission made its listing really feel barely incomplete, although it did embrace different ideas.

DeepSeek’s response to the file evaluation activity

For this one, ChatGPT wins. It gave me a extra full and technically sound breakdown, which is precisely what I wanted for a high-level tutorial abstract.

Winner: ChatGPT

8. Information evaluation 

For this activity, I threw a CSV file at each chatbots to see how effectively they may transcend the fundamentals and really interpret uncooked knowledge. I needed every AI to tug out actual traits, spot outliers, and summarize the most important insights — not simply echo again the numbers.

ChatGPT did a neat job summarizing the fundamentals: top-ranking areas, common curiosity, and even identified that there weren’t any excessive outliers. It was clear, readable, and felt like one thing you possibly can share with a common viewers.

ChatGPT’s response to the info evaluation immediate

However DeepSeek? It went deeper. It not solely flagged key knowledge factors but additionally defined why they mattered. It known as out patterns in tech adoption, steered sensible advertising purposes, and even famous limitations within the dataset — issues like lacking context and lack of demographic breakdowns. That further layer of interpretation made it really feel extra like an actual knowledge evaluation, not only a abstract.

DeepSeek’s response to the info evaluation immediate

Between the 2, I’d say DeepSeek pulled forward on this one.

9. Actual-time net search

In terms of testing real-time net searches, how “reside” these AI fashions truly are? I requested each ChatGPT and DeepSeek to tug in present information about synthetic intelligence.

ChatGPT gave me three headlines that had been extremely recent — actually only a day previous. Actually, I’ve been utilizing ChatGPT’s net searching function for some time now, and the distinction is noticeable. It was once hit-or-miss, generally laggy or pulling outdated information, however now, and particularly this time, it feels snappy and related. Getting headlines from simply the day earlier than made it really feel like I used to be chatting with a real-time information assistant.

ChatGPT’s response to the real-time net search activity

DeepSeek, alternatively, surfaced information tales that had been a bit older — most of them from mid-March. That mentioned, it clearly casts a wider web. It didn’t simply listing headlines; it included context and significance. Whereas it didn’t fairly match ChatGPT by way of freshness, it undoubtedly introduced extra breadth and depth to the desk.

DeepSeek’s response to the real-time net search activity

If I needed to sum it up, ChatGPT wins on recency, however DeepSeek makes a robust case for breadth. Is determined by whether or not you need quick or thorough. Personally, I need recent information, and in that case, it’s a clear win for ChatGPT.

Winner: ChatGPT

10. Reasoning capabilities 

For my remaining problem, I needed to see if they may actually suppose. I gave each ChatGPT and DeepSeek a traditional logic puzzle to see if they may work by way of it step-by-step. Actual-world AI must deal with difficult logic and attain sensible conclusions, so this was the final word take a look at of their smarts, not simply their solutions. 

Each ChatGPT and DeepSeek impressed me with how they dealt with the logic puzzle. ChatGPT felt like speaking to a considerate problem-solver. It didn’t simply give me the reply however walked me by way of its thought course of step-by-step. 

ChatGPT’s response to the reasoning activity

What actually stood out was the way it acknowledged that there might be a couple of legitimate resolution. That confirmed a deeper understanding of how these constraint-based puzzles work. It gave me a constant resolution but additionally confirmed how the items may shift round with out breaking the foundations, which made the reasoning really feel versatile and human.

ChatGPT’s response to the reasoning activity

DeepSeek took a extra structured strategy. It broke down the constraints clearly, examined completely different situations, and verified every clue with satisfying little checkmarks alongside the best way. I appreciated how organized and methodical it was — it felt like watching a logic grid get stuffed out piece by piece.

DeepSeek’s response to the reasoning activity

It arrived at a wonderfully right resolution and offered it neatly, however it didn’t explicitly name out the potential of alternate solutions on the finish, although it hinted at it throughout the reasoning. That made its remaining output really feel only a bit extra inflexible compared. 

Ultimately, each acquired the job achieved effectively. However for me, ChatGPT had the sting with how naturally it reasoned issues out and the way clearly it communicated the pliability within the puzzle. It simply felt a bit extra intuitive and insightful.

Winner: ChatGPT
