notes
PRIMARY, verbatim from the PDF datasheet linked on https://www.cerebras.ai/cs3. Processor Performance row: 'FP16 125 petaFLOPS*'. Processor table: '125 petaFLOPS* FP16, 21 PB/s on-chip SRAM bandwidth (44 GB on-chip SRAM)'. CRITICAL FOOTNOTE directly under the System Specifications table: '* FLOPS shown as sparse'. So the vendor DOES publish both a precision label (FP16) and a sparsity statement (sparse). VERIFY-ONLY finding for accelerators/cerebras-wse-3.json: its flops[0].notes asserts 'Cerebras publishes no precision label and no sparsity statement for the WSE family' and sets dense:true. Both claims are contradicted by the vendor datasheet. The 125 PFLOPS figure is SPARSE FP16 per vendor.
