Dual Mode

Dual Mode runs two AI models at the same time from a single Generate click. Instead of trying one model, waiting, then trying another, you get both results at once — ready for comparison.

How It Works

Select a primary model from the dropdown
Enable Dual Mode using the toggle
Select a secondary model from the second dropdown
Click Generate — both models run in parallel using the same prompt and source media

Both results appear as selectable cards. Click one to preview, import it, and the other card auto-selects so you can decide on the second result immediately.

Compatibility Check

Before generation starts, modelBridge compares both models’ inputs and identifies shared fields. Fields that represent the same concept but use different names — like prompt vs multi_prompt — are matched automatically so you only configure once.

If the secondary model has a required field with no match in the primary model’s form, generation is blocked with a specific warning.

Cost Preview

The cost badge shows the combined estimated cost for both models. The display adapts to available pricing data:

Both in USD → $X.XX · 2 models with per-model breakdown
Mixed types → $X.XX + From $X.XX · 2 models
One or both unavailable → shown honestly

A confirmation dialog appears when the combined cost exceeds $5.00.

Same-Source-Clip Handling

Both models use the same source clip. When importing:

First result imports with Replace on Timeline — the source clip is replaced
Second result automatically falls back to Insert at Playhead — since the source clip no longer exists
No conflicts — you never have to think about which result replaced what

When to Use Dual Mode

Comparing quality — test two models on the same prompt to see which works better for your use case
Speed vs quality — run a fast model alongside a high-quality model to see if the difference matters
Comparing voices — generate the same script with two TTS models
Client presentations — produce two options without doubling your workflow

Limitations

Both models always use the same source clip
Cost history logs dual generations as two independent entries
Parameters unique to the secondary model use that model’s defaults
