It as many as 100,000 tokens — that’s around 75,000 words, or a few hundred pages of documents users can have Claude digest and analyze — up significantly from the previous version’s 9,000 token limit. In AI, tokens are the bits and pieces that your input prompt gets broken down into so that the model can more readily process them — hence Claude’s ability to “digest” user data.

This increased capacity will also translate into longer, more nuanced responses. Claude 2 will even be able to generate short stories “up to a few thousand tokens,” . Its coding capabilities have also improved, rising to a score of 71.2 percent on the Codex HumanEval benchmark, up from 56 percent.
