gpt2tc is a small program using
the GPT-2
language model to complete and compress (English) texts. It has no
external dependency, requires no GPU and is quite fast. The smallest
model (117M parameters) is provided. Larger models can be downloaded
as well.
The compression ratios are much higher than conventional compressors at the expense of speed and of a much larger decompressor. See the documentation to get results on text files from well known compression data sets.
The textsynth service relies
on gpt2tc.
