T3 Chat Cuts Rendering Work 75%

This is the kind of unglamorous engineering that determines whether a multi-model chat app actually feels fast. T3 Chat is optimizing the interaction loop itself, not just adding another model.

• –Composer input no longer needs to invalidate the entire conversation on every keystroke.
• –Streaming replies update only the changing content instead of repeatedly refreshing the whole thread.
• –Lighter thread switching should particularly help mobile devices and lower-powered laptops.
• –The percentages are self-reported implementation metrics, so real-world gains will vary with thread length, attachments, and model choice.
• –For a chat product built around multiple frontier models, reducing client-side overhead is as important as improving inference speed.
