The AI chat interface
built without limits.

Access the world's best free AI models — from Llama, Gemini, DeepSeek to GPT — in one beautiful, private, locally-stored chat app.

Explain how transformers work in machine learning, then show me a minimal Python example.
Transformers are sequence-to-sequence models built around self-attention — a mechanism that lets each token look at every other token in the sequence to decide what to focus on. Unlike RNNs, they process all tokens in parallel, which is why they scale so well.

Here's a minimal example using PyTorch...

A complete AI workspace,
right in your browser.

Every feature is built-in. No subscriptions, no plugins, no hidden paywalls.

🤖
Agent Mode
Autonomous multi-step task execution. Agents plan, research, write code, and deliver results — step by step, in real time.
🔍
Thinking Mode
Unlock deep reasoning on compatible models. Watch the model think through complex problems before giving you the answer.
📎
File Attachments
Upload images, documents, code files, and PDFs. Vision-capable models analyze and reason over your files directly.
🎨
Image Generation
Generate images using Gemini 2.5 Flash Image for free. No extra setup — just enable image mode and describe what you want.
💻
Artifact Panel
Code and HTML are rendered live in a split panel. Preview web pages, download files, and switch between code and preview instantly.
🔒
Privacy First
All conversations are stored only in your browser's localStorage. Nothing is sent to our servers — your chats are yours alone.
📌

About Frost AI Hub

Frost AI Hub is a free, all-in-one AI chat platform that gives you direct access to over 30 of the world's leading AI models — including Llama, Gemini, Qwen, GPT-OSS, GLM and many more — all from one clean, fast interface, with no signup and no subscription required. Instead of paying for separate subscriptions to multiple AI services, or being limited to a single provider's models, this connects to several different AI providers behind the scenes and lets you switch between them instantly, compare their answers, and always have a working model available even if one provider is temporarily down.

Under the hood, the platform works as a smart router: when you send a message, it is securely forwarded through our serverless backend to whichever AI provider hosts your selected model, using official, provider-issued API access — nothing is scraped, faked, or reverse-engineered. If your chosen model is ever unavailable, it automatically falls back to another working model so your conversation is never interrupted. On top of plain chat, the platform includes real web search for up-to-date answers, AI image generation, code execution, exportable chat history, and a memory system that can remember small facts about you across different conversations — all running client-side in your own browser.

Is it legit? Yes — this platform does not train on your data, does not sell your information, and does not require an account. All of your conversations are stored only in your own browser's local storage, never on our servers. The platform is built and maintained as an independent, privacy-first project, and is provided as-is, free of charge, for anyone who wants flexible access to modern AI without the cost or complexity of juggling multiple subscriptions.
