Anthropic, the AI research company, has released a new version of its Claude language model, Opus 4.7. The author of the article measured the impact of the changes in the model's tokenizer and found that it has led to a 20-30% increase in the cost per session. The tokenizer is a critical component of language models, responsible for converting text into numerical representations that can be processed by the model. The changes in the tokenizer have resulted in a higher number of tokens being generated for the same input text, leading to increased computational costs and, consequently, higher pricing for users. This development is significant for developers and businesses relying on Anthropic's language models, as it may impact their budgets and project planning.
