Opus 4.7's New Tokenizer Quietly Raises Real Costs by 40%

Simon Willison upgraded his Claude Token Counter tool to compare token counts across different Claude models. Claude Opus 4.7 uses a new tokenizer that can use 1.0-1.35x more tokens than previous models, with the system prompt using 1.46x tokens. Despite identical pricing per token ($5/M input, $25/M output), this effectively makes Opus 4.7 around 40% more expensive. The tool also handles image tokens, revealing that higher resolution images (up to 2,576 pixels) in Opus 4.7 can result in 3x token increases compared to 4.6, though standard resolution images show similar costs.
