MiniMax H3 Image local image editing: 1-min edits but 25-min prompt encoding

A Reddit user reports a split experience running MiniMax H3 Image locally for image editing: the 4-step edit on a 16MP image takes only 1 minute, but with just one reference image the prompt encoding takes 25 minutes to generate 8k tokens — a major bottleneck.

Setup: default template qwen3.5 9b w4a8 + abliterate LoRA. They're asking for faster alternative models, or a way to plug in an OpenAI-compatible API (gemini, glm, gpt, nemotron, qwen, etc.) and uncensor the model.
