🚀 Đã tối ưu Top‑K cho LLM, nhanh gấp 4‑20× so với PyTorch CPU nhờ AVX2 SIMD. Benchmarks (K=50): vocab 32K → 0.043 ms vs 0.173 ms; 128K → 0.057 ms vs 0.777 ms; 256K → 0.079 ms vs 1.56 ms. Tích hợp vào llama.cpp, tăng tốc 63% (81→142 token/s) trên mô hình 120B MoE. Không cần GPU. #AI #LLM #MachineLearning #TopK #Performance #TốiƯu #TốcĐộ

1.okrągłe USB-A -> USB-A/C Intermarche tylko zasilanie, zestaw wszystkie końcówki w cenie około 20zł
2. płaskie 4 piny, #TOPK, #USB-A -> USB A/C dane, A..o TOPK, kable z wybraną końcówką
3. płaskie 5 pinów TOPK #USB-C -> USB-C dane, A..o TOPK, #kable z wybraną końcówką

A..o to znany portal i użytkownik.

Porównanie będzie uzupełniane w miarę 'sił i środków'.
