On 2 August 2010 this record was eclipsed by Shigeru Kondo who computed 5 trillion digits, although this was done using a server-class machine running dual Intel Xeon processors, equipped with 96 GB of RAM. In 2011 he won an O'Reilly Open Source Award. In 2014 he proposed the Better Portable Graphics (BPG) image format as a replacement for JPEG. In July 2019 he released QuickJS, a small and embeddable Javascript engine. In April 2021 his Artificial Neural Network based data compressor, NNCP, took first place out of hundreds in the Large Text Compression Benchmark. To write the compressor, Bellard wrote his own Artificial Neural Network library, LibNC ("C Library for Tensor Manipulation"), publicly available.
