Native model access
GPT-5.4 is built into Tabbit. Switch models, start a chat, or launch an agent without leaving your workflow.
Context-aware chat
Type @ to reference the current tab, a tab group, a screenshot, or a local file. GPT-5.4 sees what you see.
Agentic execution
Let GPT-5.4 navigate, fill forms, extract data, and run multi-step tasks in its own tab group while you keep working.
