About
Contents FLFV 8 Step Merge 0821 The 4 step LoRA was trained using shift 6 and the 8 step was trained using shift 12. I made this merge to use as a video refiner only so I recommend using v1.1 on its own for a fresh generation. If you want to try using this for a full generation, use shift 6, 8 steps and 1.0 strength.

Using it via the API
Once AxForge deploys minimax-h3-experimental for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (minimax-h3-experimental below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/videos/generations \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"minimax-h3-experimental","prompt":"a drone shot over a forest"}'
