Inkling-Small-MXFP4-AutoRound

by Intel AI intel-ai/Inkling-Small-MXFP4-AutoRound

Inkling-Small-MXFP4-AutoRound is an open-weight model for image and text to text from Intel AI, released under Apache License 2.0. It has 266B parameters. At 16-bit it needs about 638.3 GB of GPU memory, which fits on 3x MI325X from $6.00 an hour; at 4-bit, 159.6 GB on 1x MI300X from $1.85, at the lowest prices in the SAVRN Index. It draws 41 downloads a month.

This model is an MXFP4 (W4A16, groupsize 32) model of thinkingmachines/Inkling-Small generated by intel/auto-round using RTN. Please follow the license of the original model. Note: Baseline corresponds to NVFP4 reference evaluated under identical settings.

Ethical Considerations and Limitations

The model can produce factually incorrect output, and should not be relied on to produce factually accurate information. Because of the limitations of the pretrained model and the finetuning datasets, it is possible that this model could generate lewd, biased or otherwise offensive outputs. Therefore, before deploying any applications of the model, developers should perform safety testing.

Caveats and Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. Here are a couple of useful links to learn more about Intel's AI software:

A lossless repack of stepfun-ai/Step-5-Preview-NVFP4 (revision bc246cc2848e17b37f377eda8fd825c5b3018d1f), 17.1 GB smaller. The NVFP4 block scales of the routed experts are stored in b12x's compressed scale format (CSF), the lossless format introduced with nvidia/Qwen3.8-Flash-Next-FP4-Local. Every FP4 weight byte and every other tensor is identical to StepFun's checkpoint, and every scale decodes to StepFun's exact bytes, so this checkpoint computes exactly what Step-5-Preview-NVFP4 computes.
