Deprecations & Changes

As the Leonardo AI API evolves with new models, features, and improvements, we occasionally retire older ones. Some changes are driven by updates we make to the Leonardo API, while others reflect changes made by third-party model providers whose models are available through our platform.

This page lists all deprecations in reverse chronological order, with the most recent announcements at the top.

May 1, 2026 — Seedance 1.0 Lite retiring May 13, 2026

Seedance 1.0 Lite will no longer be available via the Leonardo API after May 13, 2026.

Replacement: We recommend switching to Seedance 1.0 Pro Fast — it uses the same parameter shape as 1.0 Lite, so migration is a simple model ID swap, with better latency and overall efficiency. Seedance 2.0 is also available as a premium alternative.

Action required: Update your API requests to use seedance-1.0-pro-fast (or seedance-2.0) before May 13, 2026. See the Seedance 1.0 Pro guide or Seedance 2.0 guide for usage details.

April 20, 2026 — mode parameter retiring May 4, 2026

The mode parameter for GPT Image-1.5 and Ideogram 3.0 generations is being retired on May 4, 2026. Use the quality parameter instead. After May 4, any requests that include mode will fail.

What you need to do: Replace mode with quality in your API requests before May 4, 2026. The accepted values remain the same (FAST, QUALITY, ULTRA).

Migration example

Before (deprecated):

{
  "model": "gpt-image-1.5",
  "parameters": {
    "mode": "QUALITY",
    "prompt": "A serene mountain landscape at dawn"
  }
}

After (current):

{
  "model": "gpt-image-1.5",
  "parameters": {
    "quality": "QUALITY",
    "prompt": "A serene mountain landscape at dawn"
  }
}

No other request changes are needed. For full model documentation, see GPT Image-1.5 and Ideogram 3.0.
