AI chat with Claude, GPT-6, Gemini and DeepSeek

Claude, GPT-6, Gemini, Grok and DeepSeek in one window: questions, writing, code, photos and documents. Every chat model is open even on the Free plan.

Which models are in the chat

Chat models: 48. You can switch between them in the middle of a conversation:

  • Claude by Anthropic: Opus 5.5, Opus 5, Fable 5.1, Opus 4.6, Sonnet 5.5, Sonnet 5, Sonnet 4.6 and Haiku 4.5.
  • GPT-6 by OpenAI: Astra, Sol, Luna and the new GPT-6.1 Sol, plus GPT-5.6 Luna, GPT-5.4 Mini and Nano, and GPT-5 Mini.
  • Gemini by Google: 3.1 Pro, 3.5 Flash and 3.8 Flash.
  • Grok 4.7, 4.6 and 4.3 by xAI.
  • DeepSeek V4 Flash, V4.1 Flash and V4 Pro, plus Qwen3.8 Max, GLM 5.3 Flash, Llama 3.3 70B and Perplexity Sonar.

What the chat can do

  • Files: up to 10 per message — photos, PDFs, documents and spreadsheets.
  • Almost every model understands photos. The exceptions are DeepSeek V4 Flash, DeepSeek V4 Pro and Llama 3.3 70B.
  • Web search: for questions about recent events the server turns it on by itself, and the Search button turns it on for every message. The sources show under the answer.
  • Thinking: for reasoning models you can set the thinking depth. Deeper means a more careful answer and a longer wait.
  • Discussion: three models answer the same question, and a fourth sums up.
  • Voice input works right in the message box, and you can ask for an image, a video or a game in the same conversation.

How the chat limit works

The limit follows the real cost of answers over the last 3 hours and the last 7 days, not the number of messages. Flagships use it faster: Claude Opus 5.5 at ×4 and GPT-6 Astra at ×10 compared with a regular model.

When the limit runs out, the site shows when it comes back, and DeepSeek V4 Flash and GLM 5.3 Flash keep answering within a daily allowance that resets at 00:00 Moscow time. Paid plans from 410 ₽ (≈ $4.80) give you a bigger limit.

How to start

  1. Log in with Telegram.
  2. Pick a model in the Model list above the input box.
