Engine Configuration: quality and reasoning depth

Engine Configuration is a single card on your project’s Settings page. It holds two controls that set the quality and the reasoning depth DIJJI uses on every piece of work in the project. Pick the balance you want once, and it applies everywhere.

This page is the detailed lookup for those two controls. For an overview of the app and where Settings lives, see Find your way around.

Where to find it

Open your project and select the Settings pill. The Engine Configuration card sits in the left column, below General and above the reset controls.

The card is project-wide. Whatever you set here applies to all of the project’s work — every task run, plus blueprint, documentation, and assurance work alike. It is not pipeline-specific: you can’t set a different quality or depth per stage from here.

Both controls autosave. There is no Save button — the moment you change a setting, it takes effect and is kept. New work uses your latest settings; work already running keeps whatever was in effect when it started.

Control 1 — quality and speed

The first control is a quality-and-speed tier. It offers two options:

  • Opus (default) — the higher-quality option.
  • Sonnet — a faster, lower-cost option.

Leave it on the default for the best quality, or switch to the faster option when speed and cost matter more than maximum quality.

Control 2 — Reasoning effort

The second control, Reasoning effort, sets how deeply DIJJI thinks through each step. It offers up to three tiers:

  • High (default) — the standard depth.
  • xHigh — an extra tier, available only when the quality control is on the Opus (default) option. It does not appear while the faster option is selected.
  • Max — the deepest reasoning, for harder work.

Higher effort costs more — deeper reasoning uses more credits per step. Raise it when a project’s work is genuinely hard, and keep it lower when the standard depth is enough. For how charges are calculated, see Credits and billing.

How the two controls interact

The faster option supports only High and Max — the xHigh tier belongs to the higher-quality option alone.

Because of that, switching the quality control to the faster option while xHigh is selected moves the depth down to Max for you, automatically, so you’re never left with a combination the faster option can’t run. If you switch back to the default quality option, you can raise the depth to xHigh again.
