Perplexity open-sources a 5x faster tokenizer for neural networks
Perplexity has open-sourced a rewritten version of the Unigram tokenizer. The algorithm runs 5 times faster than Hugging Face's standard tokenizers and cuts CPU load in production by 5-6x. For AI services, this matters: every millisecond saved on tokenization translates into real savings on servers. Companies can already download the code and integrate it at no extra cost.

Perplexity AI has released the open-source code for Unigram, a tokenizer for neural networks. In terms of performance, it's a genuine breakthrough: the new algorithm runs 5x faster than the traditional approach and puts almost no load on the CPU.
Why does a fast tokenizer matter?
A tokenizer gets called hundreds of millions of times a day on production servers. Any latency here adds up to serious financial losses.
