Gemini vs ChatGPT: Which AI is Better in 2025?

The AI race has changed the whole world like never before.

It all started in November 2022, when OpenAI introduced ChatGPT. A large language model capable of delivering human-like responses on almost every topic.

Since then, LLMs have transformed how we work and interact with technology. Anthropic’s Claude has emerged as a formidable competitor, and other tech companies worldwide have also launched increasingly sophisticated AI solutions.

But this competition wasn’t that dramatic until Google announced the launch of Bard AI in 2023. Bard was just as powerful as ChatGPT at launch and could match ChatGPT’s capabilities in most cases.

Later on, Google rebranded and upgraded its chatbot to Gemini, powered by more advanced models. Meanwhile, OpenAI has continued evolving ChatGPT through multiple iterations.

Both Google and OpenAI have made remarkable strides in their AI capabilities, and their flagship chatbots are vastly powerful than their original versions. But which is better in 2025, Google Gemini or ChatGPT?

Gemini vs ChatGPT at a glance

Differences between Gemini and ChatGPT in 2025

The basic difference between Gemini and ChatGPT lies in the foundation models powering them. 

While both use large language models trained to understand, interpret, and generate human language, they differ significantly in architecture and training methodology:

1. Foundational technology

Google’s Gemini uses the Gemini Ultra 2.0 model, which is built from the ground up as a multimodal AI system. Unlike its predecessor PaLM 2, Gemini was designed to process and understand text, images, audio, code, and video simultaneously. The model benefits from Google’s vast data resources and real-time internet access.

ChatGPT now runs on GPT-4o (Omni), OpenAI’s most capable multimodal model that significantly improves upon GPT-4o. While ChatGPT’s free tier still offers GPT-3.5 Turbo, GPT-4o’s has enhanced reasoning, knowledge, and multimodal capabilities. OpenAI has also expanded GPT-4o’s knowledge cutoff and reduced the problem of outdated information that plagued earlier versions.

Both models are trained on vast datasets from across the internet, but they implement different approaches to multimodal understanding and real-time information:

• Gemini Ultra 2.0 was designed from the ground up as a natively multimodal system. Means it can understand and reason across text, images, audio, and video simultaneously.
• GPT-4o represents OpenAI’s evolution toward truly multimodal AI, with significantly improved processing speed and enhanced abilities to reason across text, images, and audio.

Beyond their underlying technologies, some capability differences can also affect your user experience.

2. Multimodal capabilities

Gemini has seamless integration of text, images, audio, and video. Its Ultra 2 model can also analyze complex visual information, interpret diagrams, and even process short video clips to answer your questions.

ChatGPT has already enhanced its multimodal capabilities with GPT-4o, and multiple sources suggest that it will tremendously increase with GPT-5 (upcoming model). By that, its resource analysis capability gets more accurate than before. However, till now, 4o’s video analysis capabilities remain limited compared to Gemini Ultra 2.0.

3. Knowledge and information access

Gemini always has real-time access to Google Search. But now with its experimental 2.5 Flash model, it can pull the most current and accurate information available by deep research. This ensures up-to-the-minute facts across any topic, whether it’s for summarization, document analysis, or data extraction.

ChatGPT also improved its information access for summarization, analysis, or data extraction in GPT-4. Also, offers real-time browsing features like deep research for paid subscribers. However, the free version still operates with a knowledge cutoff that limits its ability to discuss recent events.

4. Reasoning and problem-solving

ChatGPT with GPT-4o demonstrates complex reasoning abilities, particularly for multistep problems, creative writing, and nuanced analysis. Also, OpenAI’s focus on alignment and instruction following has created an assistant that better understands user intent.

Gemini has also improved its reasoning capabilities, but still occasionally struggles with complex and multistep problems compared to GPT-4o. However, its reasoning excels when combined with information retrieval tasks.

5. Programming and technical assistance

ChatGPT hasn’t being the perfect assistance for programming previously. But in recent days, GPT-4o shows good code generation capabilities across a wide variety of languages. Its code interpreter feature allows for real-time execution and debugging.

Gemini has closed much of the gap in coding support, with specialized enhancements for software development. Its integration with Google’s development tools gives it particular strength in certain environments, though its overall coding capabilities still lag slightly behind ChatGPT.

6. User experience and integration

Gemini offers strong integration with Google’s ecosystem. This includes Gmail, Docs, Drive, and other productivity tools. According to Google blogs source, it has also expanded Gemini’s capabilities to function as an ambient assistant across all its services to create a unified AI experience.

ChatGPT has developed a vast plugin ecosystem allowing third-party integrations with tools like Notion, Microsoft Office, Adobe Creative Suite, and thousands of other services. OpenAI’s API has also enabled ChatGPT functionality to be embedded in countless applications.

7. Privacy and data usage

Gemini allows users to opt out of having their conversations used for training. However, Google’s business model still relies heavily on data collection, which might raise some privacy concerns.

ChatGPT offers stronger privacy guarantees through its Enterprise tier, which promises that data will not be used for training. For regular users, OpenAI has introduced more granular privacy controls. Though free users’ conversations may still contribute to model training.

However, all this information will give you a narrow overview of these AI assistants. To get a better understanding of how Gemini and ChatGPT compare in 2025, you need a real-time test.

Gemini vs ChatGPT: Comparing responses
