Firworks/Cassiopeia-70B-nvfp4
Cassiopeia-70B-nvfp4 is a machine learning model from Firworks. Use it for the machine learning task on the model card, and read the license before you ship it in a product. The card lists the license as unknown.

Cassiopeia-70B-nvfp4
Format: NVFP4 — weights & activations quantized to FP4 with dual scaling.
Base model: ddh0/Cassiopeia-70B
How it was made: One-shot calibration with LLM Compressor (NVFP4 recipe), long-seq calibration with HuggingFaceH4/ultrachat_200k.
Notes: Keep
lm_headin high precision; calibrate on long, domain-relevant sequences.
Check the original model card for information about this model.
If there are other models you're interested in seeing quantized to NVFP4 for use on the DGX Spark, or other modern Blackwell (or newer) cards let me know. I'm trying to make more NVFP4 models available to spread the adoption.
