Human typing habits like typos, shorthand, and filler words can unexpectedly increase the number of tokens processed by AI models, leading to higher costs. Even minor spelling errors or the inclusion of common conversational padding can result in more tokens than anticipated. This phenomenon is particularly noticeable when comparing different tokenizers, such as those used by OpenAI and Claude, which can yield varying token counts for the same text. The article highlights that while AI models might still understand the intent behind such inputs, the billing structure based on token patterns means these common human typing quirks become a direct cost.
