RIFE-4.25 is an open-weight video model from mlx-community, listed in the AxForge catalogue. AxForge can bring it up on EU-owned hardware for you on request — with the licence handled where one is required.
About
RIFE 4.25 (MLX) Apple MLX port of Practical-RIFE 4.25 — real-time video frame interpolation on Apple Silicon. MIT. First MLX/Apple-Silicon-native RIFE: torch-free inference, arbitrary-timestep interpolation, --multi Nx frame rate, --scale pyramid for 4K, audio-preserving video. Converted from the official RIFE 4.25 flownet.pkl (Google-Drive-only upstream) to fp32 safetensors. Usage Details - Architecture: IFNet (5 coarse-to-fine IFBlocks c=[192,128,96,64,32], LeakyReLU, ResConv+beta, Head encoder, ConvTranspose+PixelShuffle). - Precision: fp32 (~23 MB) — RIFE's coarse-to-fine flow is fp16-sensitive. - Parity vs PyTorch (CPU fp32): warp 2.2e-6 · interp 1.2e-7 · full IFNet 1.43e-3. License MIT (upstream Practical-RIFE, © hzwer). Weights are the official RIFE 4.25 release, converted to MLX.

How it works
Variants
Open weights ship in several sizes and precisions. One page, all the variants — pick the one that fits your GPU. VRAM figures are estimates from model size.

Using it via the API
Once AxForge deploys rife-4-25 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (rife-4-25 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":"rife-4-25","prompt":"a drone shot over a forest"}'
