Zense AI gives you access to the latest models from every major AI provider.

You can let Chat decide, or take control and pick exactly the model you want.

Different models suit different tasks — reasoning-heavy homework vs quick factual lookups vs Chinese-language writing.

Switch models

1. In a chat, open the model selector (the model name near the message box).
2. Choose one of the Chat modes, or scroll to Other Models to pick a specific model.
3. Your choice applies to the messages you send next.

Which should I use?

Let Chat choose (recommended) — the default Chat mode auto-selects the best model for each message. Great for everyday use.

Pick a Chat mode for a specific need:

• Chat-Thinking — complex reasoning, multi-step problems, tricky maths.
• Chat-Fast — quick, lightweight questions.
• Chat-Chinese — Chinese-language reading and writing.

Choose a named model when you have a preference. Available families include:

• OpenAI — GPT-5, GPT-5 Mini/Nano, GPT-4.1, GPT-4o, o3 / o4 reasoning models
• Anthropic — Claude Sonnet 4.5, Claude Haiku 4.5, Claude 3.7 Sonnet
• Google — Gemini 2.5 Pro, Gemini 2.5 Flash
• xAI — Grok 4, Grok 4 Fast
• DeepSeek, Qwen, Mistral, Meta Llama and more

All models work directly in Zense AI with no VPN needed, even where global AI tools are normally blocked.

Note: Some agent tools (like image generation) and reasoning modes may use more credits — see Credits & plans.
