Fast AI Option: Trade-offs Between Speed and Quality

Fast AI is DevSpeak's low-latency drafting mode. It is designed to give users faster feedback while they shape a request, then let them switch back to standard generation when they need a stronger final artifact.

What is Fast AI?

Fast AI watches the active translation input and triggers generation after a short idle delay. In the current implementation it prefers a lighter, faster model so the interface can return a draft quickly.

How to Enable Fast AI

Toggle the Fast AI control in the translation workspace. Once enabled, DevSpeak starts a short debounce window and then regenerates output while you type, instead of waiting for a manual submit every time.

Runtime Behavior

  • Fast AI is meant for live drafting, not large document translation.

  • The current client-side path uses a lighter model chain for responsiveness.
  • Fast-mode state is also persisted in translation history metadata so sessions can be restored consistently.

    • Impact on Output

    Fast AI reduces waiting time, but the trade-off is that draft output can be less comprehensive than a deliberate standard-generation pass. It is best used to shape the direction of a request, then followed by a final generation or refinement cycle.

    Best Practices

    When using Fast AI, consider the following best practices:

  • Use it for rapid prototyping: Fast AI is strongest when you are still shaping the request.
  • Treat the output as a draft: Review and refine before using it as final engineering guidance.
  • Disable it for heavyweight work: For larger prompts, attachments, or final architecture documents, standard generation is usually the better path.
