About the work
Complete work of the S-X quantization family: paper S-X8 v4.3 (7.50 bits per weight with FP16-level quality — perplexity within +0.2% of the unquantized model, 9× less perplexity loss than Q8_0, ~11–15% smaller files, and faster real-world decoding than Q8_0), specification of the .sx8v43 container, authorship declaration of the S-X quantization methodology, and sealed members in development (S-X6 v3, SX-FP4/NV_SX) and others. The decoder is portable by design: ALU-only, byte-aligned, no tensor-core dependency (validated on Blackwell SM120 and Maxwell GPUs).
