clef-NVFP4
NVFP4 W4A4, built with llm-compressor, for vLLM. A quantized build of Cloudflare's Clef (27B), made for "The Noise Floor of a Quantization Comparison" by Aleks Blagojevich and Trevor Sunderland (Level5). This isn't an official Cloudflare release.
These builds keep the joint schema head, the vision tower, the norms and the Gated DeltaNet gate projections in BF16. The recipes are in the repository.
