Summary

• Add a MiniMax Official Images preset for MiniMax-H3-Image and MiniMax-H3-Image-Highspeed on the MiniMax China endpoint. Canvas and Agent use the same adapter for text-to-image and prompt-based editing with up to 16 ordered PNG, JPEG, or WebP references.
• Save the provider result URL for download recovery. A timeout during submission leaves the outcome unknown and does not automatically send another billable request.

Linked issue

• Confirm the linked issue or mark as no issue.

Labels

• Apply the feature and provider labels.

Test plan

• Local, Python 3.12.15 and Node.js 26.11.1 on base 6c7f33dc plus the local changes.
  • python -m pytest tests/test_minimax_image.py -q → 3 passed. Covers generation and ordered editing requests for both models, result recovery, and timeout without resubmission.
  • node --test tests/providerPresets.test.ts → 8 passed.
  • npm run build and npm run check:i18n → passed.
• Left to CI: full regression suite.

Evidence that it works

The six canvas examples below show text-to-image generation and editing with one or two reference images. Each screenshot is followed by the original PNG.

Case	Model	Operation	Output	Result
Case 01 · NIGHT GHOST	MiniMax-H3-Image	Text-to-image	2048 × 2048	PNG adopted on canvas
Case 02 · NEURAL DRIFT	MiniMax-H3-Image	Text-to-image	2720 × 1536	PNG adopted on canvas
Case 03 · TITAN RISING	MiniMax-H3-Image	Text-to-image	1536 × 2720	PNG adopted on canvas
Case 04 · INSIDE THE TITAN	MiniMax-H3-Image-Highspeed	Text-to-image	2048 × 2048	PNG adopted on canvas
Case 05 · RED PROTOCOL	MiniMax-H3-Image	Edit with Case 01 as reference	2048 × 2048	PNG adopted on canvas
Case 06 · GHOST IN THE TITAN	MiniMax-H3-Image	Edit with Case 01 and Case 03 as references, in that order	2048 × 2048	PNG adopted on canvas

• Case 01 · Night Ghost generated image

• Case 02 · Neural Drift generated image

• Case 03 · Titan Rising generated image

• Case 04 · Inside the Titan generated image

• Case 06 · Ghost in the Titan generated image

• Case 05 · Red Protocol generated image

Provider verification

• Live MiniMax calls returned readable PNGs for text-to-image and reference-based editing. Automated tests used mocked HTTP responses to check request routing and download recovery.

Bilingual UI

• Updated and checked the preset in zh-CN and en-US.
