One subscription, many AI models: Claude, GPT, Gemini, Grok
Paying three labs for three histories is the expensive default. One plan, many models is the product shape that matches real work.
One subscription, many AI models is the opposite of juggling ChatGPT + Claude + Gemini tabs. On zy.ai you keep one history and switch engines for code, writing, and research — free models on Free; frontier models on Pro ($15/mo); capacity, Voice, and agents on Ultra ($45/mo).
What “many models” actually means
- Free models for volume and drafts
- Claude, GPT, Gemini, Grok (and peers as listed in the picker) on paid plans
- Mid-thread switches without re-pasting context
- Optional MCP tools on member accounts
Picker availability evolves; product truth is what you see after sign-in. Model instincts: Claude vs GPT vs Gemini.
Why one plan beats five logins
You pay twice for multi-lab stacks: money and memory. Every new login restarts context. One multi-model surface keeps policy, history, and files together.
