v1.3.3

meigen 1.3.3

New models

• Grok Imagine Quality (grok-image) — xAI high-quality image model, 1K/2K, supports image-to-image (up to 3 reference images).
• Grok Video 1.5 (grok-video) — xAI, image-to-video only (firstFrame required), native audio, 4–15s, 480p/720p.

Seedance 2.0

• Surface the mini tier (now the cheapest default) alongside fast/pro.
• Native 4K on the pro tier (mini/fast cap at 720p).

Fixes

• list_models now merges per-tier resolutions so Seedance Pro's 4K is no longer hidden, plus a "Resolutions by tier" line.
• Reference-video continuation is correctly shown as supported via generate_video on Seedance 2.0 (was mislabeled "web only / MCP not supported").
• Fixed grok-video duration to 4–15s; added a client-side guard for its firstFrame requirement.
• Upload gateway default domain aligned to gen.meigen.ai (legacy gen.meigen.art/api still works).
