# ChatGPT, Claude, Gemini, DeepSeek: AI assistant comparison

> AI Release · @ai_release1 · https://ai-release.org/guides/sravnenie-ii-assistentov_en.html

ChatGPT, Claude, Gemini, and DeepSeek are the most visible AI assistants in 2026. A September 2026 comparison of 15 Russian-language chatbots put them side by side for speed, accuracy, and slang understanding.

## TL;DR
- In September 2026, a top-15 list compared GPT, Claude, Gemini, DeepSeek, and other chatbots on Russian-language tasks.
- About 35 million Russians — one in four — already use neural networks, above the global average.
- OpenAI split GPT-6 into Sol and Luna; Sol is 50% cheaper and aimed at routine text work.
- YandexGPT failed a real-task test by looping for 37 minutes and burning 300,000 tokens.
- ClaudePanel, a local desktop panel from GitHub, can replace browser tabs for AI conversations.

## The September 2026 comparison

On 21 September 2026, a digest highlighted a top-15 ranking of neural-network chatbots for Russian users. The list included GPT, Claude, Gemini, DeepSeek, and others. The testers checked speed, accuracy, and understanding of slang.

The same report noted that every fourth Russian — about 35 million people — already uses neural networks. That is above the world average. These numbers set the context for choosing an assistant.

## ChatGPT: GPT-6 splits into Sol and Luna

In late September 2026, OpenAI divided GPT-6 into two working models: Sol and Luna. Sol is the cheaper version — prices are reduced by 50%. It is designed for routine tasks such as summarizing emails and generating texts.

The post does not give details about Luna, but the split shows a clear trend. Instead of one universal model, providers are offering specialized variants for different budgets and workloads.

## Claude and ClaudePanel

Claude was part of the 15-chatbot comparison, but the most concrete Claude news came from GitHub. A developer released ClaudePanel, a desktop panel that can replace browser tabs for talking to AI. It runs locally and does not require complex setup. The panel works as a separate window on top of other applications.

This is useful for people who switch between ChatGPT, Claude, and other assistants all day. A dedicated desktop window keeps the conversation closer than a browser tab.

## Gemini and DeepSeek: part of the top-15

Gemini and DeepSeek were both included in the September 2026 top-15 ranking. The test measured speed, accuracy, and slang understanding, but the posts do not reveal individual scores. What matters is that both models are now standard options for Russian-speaking users.

For a user, this means the choice is no longer between one or two names. The market has at least 15 serious chatbots, and Gemini and DeepSeek are among them.

## YandexGPT: a warning from a real test

Not all tests end well. In a real-task test, YandexGPT got stuck in an infinite loop for 37 minutes and burned 300,000 tokens without producing a result. The testers said they do not evaluate LLMs on pictures — they put a model on a real task and watch what happens.

This case is a reminder that speed and quality are not the only metrics. Stability and cost control matter too, especially when every token has a price.

## New directions: TypeSafe AI and Jev

While the big assistants focus on conversation, TypeSafe AI came out of stealth with Jev, which it calls the first "System One" model. Jev does not generate text at all. It only outputs typed decisions with probabilities.

This is a different philosophy from ChatGPT, Claude, Gemini, and DeepSeek. Instead of chatting, the model gives structured answers. It may not replace conversational assistants, but it shows where the field is heading.

## FAQ

**What is the best AI assistant in 2026?**  
The September 2026 comparison of 15 Russian-language chatbots tested GPT, Claude, Gemini, and DeepSeek, but no single winner was named in the posts. The best choice depends on your task.

**How is ChatGPT different from Claude?**  
ChatGPT's GPT-6 now has Sol, a cheaper variant for routine tasks, while Claude offers ClaudePanel, a local desktop panel for AI conversations. Both were part of the same Russian-language comparison.

**How to choose an AI assistant?**  
Look at speed, accuracy, and slang understanding — the three criteria from the September 2026 test. Also consider cost and stability, as YandexGPT's 37-minute loop and 300,000 wasted tokens show.

**What is ClaudePanel?**  
ClaudePanel is a desktop panel from GitHub that replaces browser tabs for AI chats. It runs locally, needs no complex setup, and works as a separate window above other apps.
