Convenience plays a significant role in user preferences. ChatGPT offers access via web, mobile apps (iOS and Android), and a Chrome extension, syncing conversations smoothly across platforms. Its official iOS application surpassed 10 million downloads shortly after launching.

Conversely, DeepSeek, despite providing web access, API integrations, and a Chrome extension, lacks a mobile app. One Reddit user noted,

“If not as good, it’s almost as good. I can’t tell any difference. It also has web access and costs much, much less.”

Both ChatGPT and DeepSeek are integrated with platforms such as Siri and various third-party applications. For instance, DeepSeek’s R1 model powers deep research within Perplexity, while Hugging Face utilizes DeepSeek’s Janus-Pro model for image generation. DeepSeek’s business model emphasizes sharing its technology with various applications. However, feedback towards the ChatGPT app has been mixed, with some users expressing dissatisfaction.

A user mentioned on a Reddit thread,

“The Chat GPT app is so garbage now, I don’t even know why I’m paying for it. Responses are WAY slower.”

This sentiment highlights a growing concern among users about their experience with the ChatGPT app. However, ChatGPT still maintains an edge due to its widespread availability and seamless integration with other applications, while DeepSeek earns points for its accessibility through both web and API platforms.

User Interfaces

When comparing user interfaces, both ChatGPT and DeepSeek appear straightforward and user-friendly. Their interfaces are cleanly designed and well-organized; however, ChatGPT provides greater customization options, allowing users to adjust memory, tone, and personality settings—features currently unavailable in DeepSeek. OpenAI states,

“Tools should feel like a natural extension of ChatGPT, fitting seamlessly into the conversational flow and UI.”

ChatGPT also allows users to effortlessly share conversations across platforms, a feature lacking in DeepSeek, which tends to focus more on utility than design.

Comparison of AI Models

Both ChatGPT and DeepSeek have continually updated their technology to remain competitive. ChatGPT has introduced multiple versions, including o3-mini, o1, GPT-4o mini, GPT-4o, and GPT-5 up until 2025, with each iteration improving its understanding and response generation.

The latest model, GPT-5, is capable of handling extended conversations while retaining prior context. Users can inquire, “What do you know about me?” and receive tailored responses based on earlier interactions. It also encompasses tools like DALL·E, Code Interpreter, and Browser Access.

Sam Altman, the CEO of OpenAI, remarked on GPT-5’s performance:

“It feels very fast. While testing GPT5, I got scared looking at it, thinking: ‘What have we done like in the Manhattan Project?’”

This highlights the critical concerns surrounding rapid advancements in AI technology. Not to be overshadowed, DeepSeek also progressed significantly, spending $294,000 to train its initial R1 model, a fraction of the cost of its U.S. counterparts.

The competition intensified with the release of DeepSeek’s updated R1-0528 on May 28, 2025, and later with the unveiling of DeepSeek-V3.1 in August 2025, which is inclusive of a “hybrid” mode and a context window of 128K tokens. An experimental version, V3.2-Exp, is also expected by September 2025.

On Reddit, users shared their impressions, stating,

“The model is absolutely rock solid. As we got further through the process, we were after the race, as once again.”

Nevertheless, users have reported that DeepSeek V3 occasionally provides inaccurate information, with concerns arising about the anticipated R2 version; however, details remain unconfirmed. GPT-4o, GPT-4o mini, and DeepSeek V3 serve as standard AI language models, adept at generating text and engaging in conversation naturally, while models like o1, o3-mini, and DeepSeek R1 are recognized for their reasoning capabilities — they analyze inputs more thoroughly before offering responses, resulting in slower output times. A comparative chart illustrates the varying performance levels across different AI models based on reasoning, accuracy, coding skills, and writing quality.

ChatGPT’s DALL·E 3 integration empowers it to create realistic images, alongside its voice chat feature, allowing users to convey commands through audio instead of typing for hours. In contrast, DeepSeek is still evolving its multimodal capabilities. It has introduced Janus-Pro, an image generation model on Hugging Face, to produce intricate and artistic visuals from text prompts. However, integration remains less fluid than its ChatGPT counterpart, which currently dominates in the multimodal space.

OpenAI,

“ChatGPT can now search the web in a much better way. Ask a question in a more natural, conversational way, and ChatGPT can choose to respond with information from the web.”

Many users have commented on how much faster and more accurate this feature has become, enhancing the overall knowledge base. In comparison, DeepSeek lacks a comprehensive web search capability and visual integration, relying instead on retrieval-augmented generation (RAG) to access information from external databases and documents.

DeepSeek R1 synthesizes data from documentation and combines it with reasoning to deliver clear, evidence-based responses. Therefore, if you prefer a tool that mimics a smart search engine within your chat, ChatGPT would be the optimal choice. Conversely, DeepSeek’s RAG-oriented model may better serve those requiring specialized document creation.

Privacy

Privacy concerns are paramount when using tools like ChatGPT and DeepSeek. ChatGPT collects extensive user data—including messages and uploaded files—which can be used to train future models unless users choose to opt out. This means that unless users actively change their settings, their conversations may contribute to the AI’s learning material.

A user on Reddit pointed out the nuances of the privacy approach:

“It’s nice that we can opt out, but by default, OpenAI still collects prompts and responses.”

While OpenAI has made strides By introducing options for businesses to maintain privacy, lingering concerns remain about the duration of data retention and compliance with international privacy regulations like GDPR. In certain instances, reports observe that ChatGPT can retain user data indefinitely.

Deleted screenshots and browsing histories persist for up to 90 days. Conversely, DeepSeek’s situation raises more serious alarms. Various reports allege that it poses national security threats, with a recent U.S. government investigation alleging that DeepSeek serves as

“the CCP’s latest tool for spying and stealing U.S. technology.”

According to the report, user data from the U.S. is transmitted to Chinese servers, and there are concerns regarding DeepSeek’s alignment with Chinese government narratives. An additional report from Wired has confirmed these troubling claims, noting that data from U.S. users is sent to servers based in China.

Moreover, cybersecurity experts caution that DeepSeek employs weak encryption methods, potentially exposing user device information to third parties. This situation has led agencies such as the U.S. Department of Commerce to prohibit the use of DeepSeek on government devices.

With emerging AI tools, it’s prudent to be cautious about sharing sensitive or personal information until clarity on data usage and privacy safeguards is assured.
