Artificial intelligence and neural networks are used not only for generating texts and solving mathematical problems. They are also widely applied in medicine, scientific research, finance, marketing, and advertising. There are many different neural networks — some generate only textual data, others create images and videos, and some work with vector graphics.
Today, we will take a detailed look at the 8 best AI apps to use in 2025: Grok, ChatGPT, Gemini Ultra, DeepSeek, MidJourney, Claude, Sora, and Recraft.
Our list of the best AI applications in 2025 opens with the AI from xAI called Grok.
Grok was designed with a focus on processing and analyzing complex queries. The AI can not only generate text but also, for example, explore social media user profiles, verify links, and analyze uploaded files (including images and PDF documents). The third version of the AI differs from the previous versions (Grok 1 and Grok 2) by improved performance, extended functionality, and a changed approach to training.
Key features of Grok 3 include:
Increased computational power. The model was trained on the Colossus supercomputer equipped with approximately 200,000 Nvidia GPUs, which significantly increased accuracy and depth of data processing.
New versions of built-in models. Grok 3 introduced new models — Grok 3 Reasoning and Grok 3 mini Reasoning. These models use a “chain of thought” approach that allows them to analyze tasks step-by-step, verify their conclusions, and correct mistakes.
Information retrieval from various external sources. Grok 3 has introduced a new feature called DeepSearch, which searches the internet and social media, providing the AI with more flexibility in information retrieval and response generation.
Use of synthetic data. Earlier Grok versions primarily used human-created data. Grok 3 actively incorporates synthetic data in training, increasing model adaptability and reducing bias.
New functionality. Grok 3 includes new modes — Think and Big Brain — which enhance the response generation process for complex queries.

No list of the best AI applications would be complete without mentioning ChatGPT. The flagship product of OpenAI, released in late November 2022, caused a sensation worldwide. ChatGPT can be used for a wide range of tasks, from creating texts of any complexity to use in medicine and scientific research.
As of May 2025, the latest version is ChatGPT-4.5, which offers the following features:
Multimodal support. This means the model can analyze images along with text. For example, a user can upload an image and ask the AI to describe it or answer questions about its content.
Improved accuracy in responses. ChatGPT 4.5 significantly improves fact-checking and generates more accurate answers compared to versions 3.5 and 4, which sometimes provide unverified or false information.
Enhanced safety mechanisms. Version 4.5 features stronger filters to reduce bias and improve safety, resulting in fewer inappropriate or offensive responses.

Search giant Google also contributed to the development of neural networks by releasing Gemini Ultra in December 2023. As a multimodal neural network, Gemini Ultra is integrated into Google’s ecosystem. It processes not only text data but multimedia, including images and videos. The AI’s applications range from search and data analysis to creative content generation. Gemini Ultra is considered a serious competitor to ChatGPT.
Key features include:
Support for multiple data formats. Unlike most other models, Gemini Ultra was built to handle various data types (text, images, audio), enabling it to analyze images or generate code from text prompts.
High performance in query processing. Based on a multimodal architecture, Gemini Ultra shows impressive results in tasks requiring cross-modal reasoning.

Chinese company DeepSeek, developer of the AI of the same name, caused a sensation in the AI world. On January 27, 2025, when DeepSeek R1 was released, it became the most downloaded AI app worldwide and caused market excitement, affecting stock prices of global tech firms (Nvidia, Advantest, Tokyo Electron, Renesas Electronics, SoftBank Group). This was preceded by news that DeepSeek R1’s development cost was much lower than competitors. It also used fewer chips and had an optimized architecture. Communication between chips was enhanced to reduce data volume for memory saving and implement the Mix-of-Models method.
DeepSeek R1 positions itself as a competitor to ChatGPT and other language models. Its applications range from solving math problems and learning programming to composing complex texts and writing scientific articles.
Main advantages of DeepSeek R1:
Architecture. It uses a Mixture-of-Experts architecture, consisting of many specialized subnetworks, each handling specific data types or tasks, providing high performance with less computational cost compared to similar-sized models.
Open source. Unlike most AI models, DeepSeek R1 is open source, allowing users to view, improve, and modify the AI code.
Training process. Training uses Reinforcement Learning, a method where the AI learns by trial and error to optimize its decisions and become smarter.

While many neural networks focus on text, the popular Midjourney AI changes the interaction by generating images from text prompts.
Version V6.1, released in July 2024, has the following features:
Improved image quality. Generated images look much better—more detailed, realistic, and with natural textures.
Better handling of complex requests. It processes complex prompts more effectively, reducing the need for repeated clarifications.
New upscaling modes. Two new upscaling modes were added: Upscale Subtle (doubles resolution without altering the image) and Upscale Creative (also doubles resolution but adds creative changes). Both enlarge images up to 2048x2048 pixels.
Faster image generation. A Turbo mode introduced in March 2024 speeds up generation by 3.5 times.
Claude 3 is a neural network and family of language models released in March 2024 by Anthropic. It is positioned as a versatile solution for a wide range of tasks and an alternative to other neural networks such as ChatGPT, Grok, Gemini Ultra, etc. Claude 3 is trained on a variety of internet text data and incorporates extensive user feedback to improve response accuracy.

OpenAI, best known for ChatGPT, released a new service called Sora in February 2024. It generates short (up to one minute) Full HD videos from user text descriptions. The model was trained on a large video dataset and can create videos on various topics.
Features include:
Full built-in video creation functionality. Besides generating videos from text, Sora includes editing tools like Remix (element modification), Storyboard (scene assembly), Loop (looping), and Blend (video transitions). Style support is also available.
Closing our list of the top AI apps is Recraft, a tool for creating and editing images and graphic content. Launched in 2023, by 2025 it became popular among creative users. Recraft can create images based on text descriptions with specific styles and edit existing images by removing/replacing objects or changing backgrounds.
Main features:
Creation of various image types. Can generate both raster and vector graphics.
Customization. Users can select size, style, color palette, and fine-tune details like color, element placement, detail level, and add text.
