Generation History

Generation History is a built-in editor window that tracks every AI request made within the Unity Editor. All requests — text generation, image generation, speech, and more — are automatically recorded and persisted to a local JSON file.

Opening the Window

Go to Tools > AI Dev Kit > Generation History in the Unity menu bar.

Features

Record List

All records are displayed in a sortable tree view with the following columns:

Column	Description
★	Mark a record as a favorite
Date	Timestamp of the request
Model	AI model used
Request	Endpoint/request type (e.g. Chat, Image, TTS)
Input	Prompt or input text
Output	Generated response or result
Cost	Estimated token cost
Sender	Agent or component that initiated the request

Toolbar

• File menu — Save a snapshot of the current history, load a previous snapshot, or clear all records.

• Search — Filter records by keyword.

• Favorites filter — Show only starred records.

• Archive filter — Show only archived records.

• Total cost — Displays the cumulative estimated cost of all visible records. Click to recalculate.

Snapshots

Snapshots are point-in-time backups of the full history file. A snapshot is automatically created before any destructive operation (e.g. "Clear All Records").

• Saved as ai_request_history_snapshot_<timestamp>.json inside the AIDevKit data folder.

• Can be listed and restored via File > Load Snapshot.

Context Menu

Right-clicking a record exposes:

• Copy Prompt — Copies the input prompt to the clipboard.

• Copy Response — Copies the generated output to the clipboard.

• Delete — Removes the selected record(s) from history.

Storage

Records are stored locally at:

<Application.persistentDataPath>/Glitch9/AIDevKit/ai_request_history.json

Legacy files (prompt_history.json) are automatically migrated to the new format on first load.
